HKCR where is located. Where is the Windows registry? How to open a Windows registry

Windows registry ( Windows Registry. - system registry) - This is a hierarchical (tree) database containing records that define parameters and settings for operating systems Microsoft Windows.. The registry as it looks like when viewing the registry editor is generated from the data sources of which are the registry files and equipment information collected during the download process. In the description of the registry files on english language Used term "Hive". In the documentation from Microsoft this term translates as "Bush".

The main files responsible for the formation of the registry

Registry files are created during the installation of the operating system and stored in the folder:

% Systemroot% \\ System32 \\ Config (usually C: \\ Windows \\ System32 \\ Config).

For Windows operating systems, these are files with names:

System.
Software.
sam
Security
Default.
Components.
BCD-TEMPLATE.

In operating systems Windows Vista., Windows 7, Windows8 ,, Registry files are located in the catalog \\ Windows \\ System32 \\ Config and have the same names, but in these operating systems added new section Registry for storage ( Boot Configuration Data.) With name BCD00000000.. The file with the data of this section has a name. bCD. And is B. hidden folder Boot active partition (partition from which system boot). Usually, with standard windows installationThe active section of a small size (from 100 to 500 megabytes, depending on the operating system), which is hidden from the user and contains only the service data for loading the system - boot records, download manager bootmgr., download configuration storage BCD., Localization files and memory test programs. Bust location bCD. It depends on how the system loader is configured when it is installed, and may be located on the same section where Windows directory.

The location of the registry files in any version of Windows can be viewed using the registry editor, in section:

HKEY_LOCAL_MACHINE \\ SYSTEM \\ CURRENTCONTROLSET \\ CONTROL \\ HIVELIST

This section stores information about all bushes, including user profiles, with reference to their location in file System Windows.

Registry structure

The Windows registry has a tree structure and consists of 5 major registry sections:

HKEY_LOCAL_MACHINE (HKLM) is the largest registry key. It is focused on all the basic settings of the operating system, as well as hardware and software Computer. The information contained in this section applies to all users registering in the system.

HKEY_ CLASSES_ ROOT (HKCR) - contains associations between applications and file types (by file extensions). In addition, this section contains information on registered file types and COM and ActiveX objects. Besides HKEY_ CLASSES_ ROOT. This information is also stored in the sections. HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER.. Section HKEY_LOCAL_MACHINE \\ SOFTWARE \\ CLASSES Contains default parameters that relate to all users local computer. The parameters contained in the section HKEY_CURRENT_USER \\ SOFTWARE \\ CLASSESOverride the default and relate only to the current user. Section HKEY_CLASSES_ROOT. Includes data from both sources.

HKEY_USERS (HKU) - contains environment settings for each of the loaded user profiles, as well as for the default profile. IN Hkey_users. There is an invested section \\ Default., as well as other subsections defined by the security identifier ( Security ID, SID) Each user.

HKEY_CURRENT User (HKCU) - builds the settings of the user for the user, on this moment registered in the system ( variable environment, desktop settings, network settings, applications and connected devices).

This section duplicates information in HKEY_USERS \\ User SIDwhere user SID - the user security identifier registered in the system at the current time (you can learn from the SID of the current user by typing command line wHOAMI / User.).

HKEY_CURRENT_ CONFIG (HKCC) - contains settings for the current hardware profile. The current hardware profile includes sets of changes made to standard configuration Devices specified in subsections Software. and System. root section HKEY Local_machine.. IN HKEY_CURRENT_CONFIG. Only changes are reflected. In addition, the information of this section is in HKEY_LOCAL_MACHINE \\ SYSTEM \\ CURRENTCONTROLSET \\ HARDWAREPROFILES \\ CURRENT.

The data in the registry is stored as parameters located in the registry keys. Each parameter is characterized by a name, data type and value.

The main types of data used in the registry

REG_DWORD - 32-bit number. This type of data is used by many device drivers and services. Registry editors can display this data in a binary, hexadecimal and decimal format.

REG_SZ - a text string in a format, convenient for human perception. The values \u200b\u200bof the descriptions of the components are usually assigned to this particular data type.

REG_EXPAND_SZ is an extensible data line. This string is a text containing a variable that can be replaced when calling from the application side, for example, is used to record environment variables.

REG_MULTI_SZ - multi-line field. Values \u200b\u200bthat actually represent lists of text strings in a format convenient for perception by man usually have this type of data. Rows are separated by NULL symbol.

REG_BINARY - binary data. Most hardware components use information that is stored as binary data. The registry editors displays this information in hexadecimal format.

REG_RESOURCE_LIST - List of hardware resources. Applies only to branches HKEY_LOCAL_MACHINE \\ HARDWARE..

You can also sometimes meet such registry data types:

REG_RESOURCE_ REQUIEMENTS_LIST. - List of necessary hardware resources. Applies only to branches HKEY_LOCAL_MACHINE \\ HARDWARE..

REG_FULL_RESOURCE_ DESCRIPTOR - descriptor (descriptor) of the hardware resource. Applies only to branches HKEY_LOCAL_MACHINE \\ HARDWARE..

REG_QWORD - 64-digit number.

REG_DWORD_ LITTLE_ENDIAN - 32-bit number in "Pointed" format (Little-Endian), equivalent REG_DWORD..

REG_DWORD_BIG_ ENDIAN - 32-bit number in the format of "stupid" (Big-Endian).

REG_QWORD_LITTLE_ ENDIAN - 64-bit number in "Pointed" format. Equivalent REG_QWORD..

REG_NONE - The parameter does not have a specific data type.

Interaction of the registry with the operating system

When the computer starts, the hardware recognizer ( hardware Recognizer.) Places the list of devices detected by them in the registry. Usually the recognition of hardware is carried out by the program. NtDetect.com. and operating system core Ntoskrnl.exe.

When starting the system of the system, the system retrieves information about the downloadable device drivers and the order of their download. In addition, the program Ntoskrnl.exe. Transfers information about yourself to the registry (eg version number).

In the process of loading the system, the device drivers exchange with the registry of loading parameters and configuration data. Device driver reports used by him system resources, including hardware interrupts ( IRQ.) and memory access channels ( DMA) So that the system can include this data in the registry. By the way, the registry allows you to create several hardware profiles. Hardware profile ( hardware Profile) is a set of instructions with which you can specify operating system, What devices drivers should be downloaded when you start the computer. By default, the system creates a standard hardware profile, which contains information about all hardware detected on the computer.

When the user logins, the user profiles are loaded into the system ( user Profiles). All information relating to a specific username and rights associated with it is kept in the registry. The user profile defines the individual system settings (display resolution, parameters network connections, Connected devices and much more). Information about user profiles is also kept in the registry.

When installing applications. Each time you start the installation program, the new configuration data is added to the registry. Starting your work, all installation programs should read information from the registry to determine whether the components they need in the system are present. In addition, the system registry allows applications to share configuration information, which provides them more possibilities For interaction. The application must actively and correctly use the registry, as well as be able to correctly remove without affecting the components that can be used by other programs (libraries, software modules etc.). This information is also kept in the registry.

When administering the system. When the user makes changes to the system configuration using system administration tools (for example, using Control panels or equipped MMC.), All changes are immediately reflected in the system registry. In fact, administration means are the most convenient and secure means of modifying the registry. By the way, the registry editor can be attributed to administration tools. regedit.exe), because all changes to the system can be made directly by the editing registry.

■ In the process of loading and operating the operating system, a constant reference to the registry data is performed for reading and write. The registry files are constantly changing, since not only the system, but also individual applications can use the registry to store your own data, parameters and settings. In other words, the registry appeal is one of the most common operations. Even if the user does not work at a computer, referring to the registry is still performed by system services, drivers and applications.

In inexperienced PC users, the Windows registry is associated with something completely incomprehensible and very complex. After reading the decryption of this concept in the textbook, the panic is even more enhanced. After all, it is clearly indicated that the slightest failure in the registry leads to violations of the system. Therefore, to know, at least in general features, what is the Windows registry And where he is, should each user. Today, I will help you deal with this important element.

So, I will start directly from the registry determination. Roughly speaking, it is a huge database in which all parameters and operating system settings are grouped. Information is systematized and grouped by certain parameters. After requesting the user, a specific component is activated.

IN registry A hierarchical structure is strictly observed. Those. There are main, and subordinate elements. You can see the database using the built-in program, which is called the registry editor. She is present by default in all versions of Wiindows. To get to it, you need to click the Start button and select Point in the dropped menu:

After that, a window will open, which will ask you to enter the name of the item you want to open. You should enter the word "regedit" in this field and click on the OK button.

Where is the Windows registry?

And so before us registry In his best. As you can see, it consists of five main points. The name of each of them begins with HKEY, then it costs the "_" icon, and the name of the section is directly. The left field of the opened window is designed to remove more complete information about the selected element.

HKEY_CLASSES_ROOT contains information on the expansion of each type of file registered in the system, and information about embedded SOM servers.

HKEY_CURRENT_USER includes all the information associated with the work of a specific user, which is currently working with a computer.

HKEY_LOCAL_MACHINE Keeps the largest amount of information. This contains the data of the driver, software and their settings.

HKEY_USERS includes information that is relevant for all users having access to the operating system.

HKEY_CURRENT_CONFIG contains data about all the equipment that functions at the time of launching a computer. Here you can detect a list of all drivers and choose that of them that is needed at a particular time system.

These five items are root folders. In each of them there are still subordinate folders in which all important data contains. To view the contents, you just need to click on the "+" icon near the folder name. A branch will open, which in turn can also consist of several subparagraphs. To make the drop-down lists again, you need to click on the square with "-".

Registry sections Store the data required for the stable operation of the computer. It saves information about user profiles, installed equipment and software, properties. This data is regularly read by the system during the start, directly operation and shutdown.

The registry constantly enters new volumes of information. After all, the system is constantly updated with new equipment and programs. In addition, not every user can boast that unnecessary programs With the help of special removal and disinstral masters. Many simply send the selected folder to the basket. But this method only visually eliminates the program. And all the information still remains in the system. It is not surprising that with time the registry can grow to large sizes. In such conditions, the amount increases system errors, uninterrupted work on the computer becomes impossible. To solve this problem, you need to clear the registry from extra. Those. It should be found unnecessary files And remove them. This procedure can be carried out in manual modeand with the help of special programs.

Generally, registry - This is a well-ordered database in which all information needed for stable operation of the system is systematized and is ordered. It should not interfere in its structure without much knowledge. But be afraid that some registry point will be damaged by the lacaround, too. After all, now you know where this important element is located, and you will not make changes to it without fail.

Good luck to everyone in the knowledge of exciting and useful science of competent computer management! Until.

Today, we will try to figure out what the main Windows registry is, for which it is necessary. We will also try to answer the question of where the Windows XP and Windows 7 registry is located.

Register of Windows: what it is for what

First of all, you need to assimilate that the registry is not a folder. The registry is a whole file that meets all parameters of the usual file. You can find this file in the Windows folder. If you want to view the Windows registry, you need to do the following. Open the Start menu. Then the "Run ..." option. Introduce the inscription "REGEDIT" in the string.

Directly, the registry itself is in two files. They are called "user.dat" and "System.dat". There is also a "policy.pol" file, which contains all the rules of the system. This file data has a priority in front of any registry settings. It, as a rule, is used in a multiplayer environment and it is not installed by default. All these files can be found in windows folderwhere the entire computer system is located. It is categorically not recommended to change the contents of the folder, it can lead to logical errors capable of incoring your computer. One moment should be taken into account. If there are several user accounts on the computer, the system creates several "user.dat" files.

Here is a list of Windows registry files:

C: \\ Windows \\ System32 \\ Config:
Software-HKEY_CURRENT_CONFIG
System - HKEY_LOCAL_MACHINE, HKEY_CLASSES_ROOT
DEFAULT - HKEY_USERS.
C: \\ Documents and Settings \\% User%
NTUSER.DAT - HKEY_CURRENT_USER.

Registry Windows 7: Where is

Where is the Windows XP registry

The Windows XP registry is in the Windows / System32 / Config directory.

What does the registry answer? The registry contains all the information for the correct operation of all hardware devices, programs, user accounts and properties of your personal computer. All changes very different settings Displayed in the system registry. The registry has a hierarchical structure. The program "Regedit" is a conductor over the entire registry system. Without this utility it would be impossible to work effectively with the registry, although sometimes it is necessary. Each main branch is the root folderwhich contains the required system, keys. Each key, respectively, may contain other keys called parameters or connections. They contain all the actual information about the changes in the operational system. Programmers allocate three types of plugs - these are string, binary and DWORD keys. The registry has six main branches, between which all the information is distributed, which is contained on the computer.

Experts on computers and software categorically do not recommend changing or deleting anything from the Windows registry. If you think that the problem of hanging lies in the registry, then it is better to contact a specialist who will accurately help you correct system errors.

Windows Registry (Eng. Windows Registry), or a system registry - a hierarchically constructed parameter database and settings in most Microsoft Windows operating systems.

The registry contains information and settings for hardware, software, user profiles, presets. Most changes in the control panel, file associations, system policies, the list of installed are fixed in the registry.

The Windows registry was introduced to streamline the information stored before in a multitude of INI files, ensuring a single mechanism (API) of the recording-reading of settings and get rid of the problems of short names, the lack of delimitation of access rights and slow access to INI files stored on the file system FAT16, having serious performance problems when searching for files in directors with large numbers. Over time (finally - with the appearance of a file nTFS systems) The problems solved by the registry disappeared, but the registry remained due to backward compatibility, and is present in all windows versions, Including the latter. Since now there are no realistic prerequisites for using such a mechanism, Microsoft Windows is the only operating system from the currently used today, which uses the operating system registry mechanism. In general, the registry is rudiment.

Windows registry in the current form.

The registry as Windows uses and how it sees its user in the process of using the registry work programs, is formed from various data. So that it seems that the user sees, editing the registry, the following happens.

Initially, in the installation process (installation) and windows settingsThe disk forms files in which part of the data relative to the system configuration is stored.

Then, in the process of each system loading, as well as during each input and output of each user, a certain virtual entity is formed, called the "Registry" - the Registry \\ object. Data for the formation of the "Registry" is partially taken from those of the most files (Software, System ...), partly from the information collected by NtDetect when loading (HKLM \\ Hardware \\ Desription).

That is, a portion of the registry data is stored in files, and part of the data is formed in the process. windows downloads.

To edit, view and exploring the registry standard means Windows (regedit.exe and regedt32.exe programs) are available for the registry branches. After editing the registry and / or make changes to it, these changes are immediately recorded in files.

However, there are third-party programs that allow you to work directly with files.

Registry optimization programs, tweaks, as well as installers and programs uninstallastors operate through special function of working with the registry.

Where are the Windows registry files?

The registry files are in the Windows Folder \\ System32 \\ Config \\ still there is a custom registry key - in the UserProfile% \\ Ntuser.dat file.Backup copies of the registry files are located in the Windows \\ System32 \\ Config \\ Regback folder.

What are the main sections (bushes) of the registry?

Section HKEY_CLASSES_ROOT.

This is the main Windows registry key, it contains file associations that link file types with programs that can open and edit them and register classes for Component objects Object Model (COM is a component model of objects). The latter provides the ability to change the incredible number of the rules of the system behavior - it is not necessary to do this without a pricing cause.

Section HKEY_CURRENT_USER

He keeps the settings of the current active user. In the branch stored user folders, various personal settings and control panel parameters. This information interact directly with the user profile. This branch consists of several subsections that contain ways. sound Filesused to voicing system events; Various data that can be changed in the control panel, for example, ordering icons; Information on the current keyboard layout, user application settings, etc.

Section HKEY_LOCAL_MACHINE

Here the configuration parameters are stored, which relate to this computer (parameters are set simultaneously for all users). For example, here contains information about the configuration of the computer, installed drivers and programs, name of ports, file system parameters, etc.

Section HKEY_USERS

This branch contains information about the profiles of all users. this computer (username, desktop settings, etc.). Also, this section stores default settings for the desktop, the "Start" menu, etc. They are needed in cases where new user enters the system for the first time. At this point, the default settings are copied to its profile, and all further changes made by the user will continue in this branch.

Section HKEY_CURRENT_CONFIG

The key is responsible for the Plug & Play devices and contains information about the current configuration of the computer with variables of devices, such as flash cards, printers, faxes, external drives etc. Also, this section contains information about the current equipment profile, which is used by the computer when starting the system.

HKEY_DYN_DATA.

This section is available only in the OS registry. windows family 9x / me. Contains dynamically changing computer data (processor load, paging file size, etc.)

How to edit the registry?

All just B. search for Windows. We gain regedit. And launch the registry editor on behalf of the administrator. Before performing any operations in the registry must be made backup! If something goes wrong, you can return to the operating version of the registry.

Optimization of the registry.

There are disputes about whether to optimize the Windows registry. I would say so for more weak computers Optimization is more useful than for powerful. But there is another nuance sometimes not cleared registry parameters can cause malfunctions and conflicts of software and hardware, so I recommend cleaning the registry from unnecessary data.

In addition, the registry with time is fragmented, this happens including due to cleaning. Therefore, those who do the cleaning of the registry constantly I also recommend sometimes to do the registry defragment.

To optimize the Windows registry, you can use programs, WinopTimizer, Reg Organizer., Auslogics boostspeed.

If you have any questions watch the video above.

The registry is the most important component of the Windows family operating systems. It is quite complicated to understand the usual user. What is the Windows registry? The registry is a centralized database that stores all the settings of the operating system and applications running in it. The registry contains information about all hardware devices, information about file name extensions, all system components and operating in the system applications, network parameters, security information, etc.

Thus, if on the computer under windows control There is a software or hardware component affecting its work, then all information about this component is stored in the Windows registry. The scheme below shows a simplified model demonstrating system components And their interaction with the registry.

Consider in more detail how windows components 7 interact with the system registry:

Windows SETUP program - when you first start collects system information and creates a registry based on the data obtained. When installing drivers or applications, the installer program reads information from the registry and add its configuration data there. The presence of the registry allows the entire program to access the centralized database and interact with each other. In addition, the information stored in the registry allows you to correctly remove the application, while not affecting such important components as, for example, the DLL library.
Wednesday windows restoration (Winre) - a set of means designed to diagnose the damaged system and restore it after serious errors. Winre actively works with the registry, and one of the tasks performed is the restoration of the damaged registry.
Windows Download Manager ( Windows Boot. Manager) - the download manager gets access to the BCD database (Boot Configuration Data), which is stored in the registry. After reading the configuration data, the download manager transmits the Windows loader control to the WinLoad.exe file, which, first of all, reads the necessary data from the registry, and then loads the kernel of the operating system (% System32% \\ Ntoskrnl.exe) and the level of hardware abstractions ( % System% \\ Hall.dll), as well as all initial boot drivers and dll kernel mode. That is why in the absence or damage of files the registry, the operating system simply will not boot.
PNP Manager - Responsible for Detection Device for two parameters: Supplier ID, VID and Device ID, DID). When the PNP dispatcher defines a unique combination of VID and DID, it requests information about the bus on which the device is detected and whether the driver is checked for this device. In case the driver is not installed, the PNP subsystem must find a suitable INF file to install the driver and start it.
Power Manager (Power Manager) - closely interacts with PNP Manager, applications, supports a variety of power management schemes and managed by group policies, and all this information is stored in the registry.
Device drivers are exchanged with the registry of download parameters and configuration data. The driver must report on the system resources used by them. Application applications and drivers can read this information from the registry, providing users with convenient tools for installation and configuration.
Administrative funds - administrative windows, Including utilities from the control panel and programs from the administration group is the most convenient and secure means of modifying the registry.
Custom Profiles (User Profiles) - all information related to a specific account The user and the rights associated with it is stored in the registry. Group politicians Also stored in the registry.
Hardware Profiles - is a set of instructions with which you can specify the operating system, the drivers of which devices must be loaded when the computer starts.
File systems - starting with Windows Vista both file systems and the registry are based on transactions. In practice, this means that if the set of operations on files and the registry is marked as a transaction, then in case of failure, at least one of these operations, the entire transaction can "roll back" to its original position.
Subsystem windows security 7 - Security subsystem with all of her functionality, including accounting of accounts (User Account Control, UAC), is also implemented on the registry base and is used to protect it. The principle of operation of the UAC is to limit the privileges provided by the launched applications, the privilege level of a regular user. In other words, even if the user running the application and has administrative rights, the applications running such privileges do not have, unless the user explicitly starts them on behalf of the administrator. Thus, with an elevated privilege level, only applications that the user trusts are launched.
Windows network components - include drivers network adapters, settings for network protocols and services, as well as parameters network security and network protection from attacks. All this is also kept in the registry. For example, database Windows Firewall (Windows Firewall) Located in the registry. Many third-party firewalls also create their keys in the registry, and, therefore, a successful attack on the registry opens the way to the invasion of the outside.

The file system on the hard disk has a lot of things in common with the logical registry structure. The registry contains keys (keys) and parameters (values) that match the directories and files on the hard disk. Registry keys may contain invested keys (subdirectories). Registry parameters (as well as files) stored data. Keys on the very upper level Hierarchy, called root keys (root keys). The key naming scheme and registry parameters are similar to the path in the file system. Typical path to the investment key of the registry HKEY_LOCAL_MACHINE \\ SYSTEM \\ CURRENTROLSET.The Windows 7 registry contains five root keys: HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_USERS, HKEY_CURRENT_CONFIG.

To go to the Windows 7 registry, Press the key combination win + R. (Follow the "Run" window), then enter and press ENTER.

The registry editor window appears.

All root key names begin with a row HKEY_,what points to software developers to the fact that this is a descriptor that can be used by the program.

Descriptor (handle) is a value used for a unique description of the resource to which the program can access.

The description of the root keys is shown in the table below.

The name of the root key	Description
HKEY_LOCAL_MACHINE	Contains global information about hardware and operating system, including: Type Type, system Memory, Device drivers and control data used when starting the system. The information contained in this key operates in relation to all users registered in the system. At the top level of the registry hierarchy for this key there are three pseudonyms: HKEY_CLASSES_ROOT, HKEY_CURRENT_CONFIG and HKEY_DYN_DATA.
HKEY_CLASSES_ROOT.	Contains associations between applications and file types (by expanding the file name). In addition, this key stores OLE information associated with cOM objectsas well as data on associations of files and classes.
HKEY_CURRENT_CONFIG.	Contains configuration data for the current hardware profile. Hardware Profiles are sets of changes made to the standard configuration of services and devices set by the data of keys. Software. and System. core keys HKEY_LOCAL_MACHINE.In the key HKEY_CURRENT_CONFIG. Only changes are displayed.
HKEY_CURRENT_USER.	Contains the user's profile at the moment registered in the system, including environment variables, setting up the desktop, network settings, printers and applications. This keys are a link to the HKEY_USERS \\ user_sid key, where the user_sid is the security identifier (Security ID) of the user registered in the system currently.
Hkey_users.	Contains all currently loaded user profiles, including HKEY_CURRENT_USER, as well as custom profile Default (.Default). Users receiving remote access To the server, do not have profiles contained under this key - their profiles are loaded into registries on their own computers.

The registry data is maintained in the form of parameters located under the registry keys. Each parameter is characterized by the name, data type and actually value. Three parts of the registry parameter are always located in the order shown in the figure below:

The table below lists the main types of data specified and used in Windows 7.

The name of the root key	Description
REG_BINARY.	Binary data. Most hardware components use information that is stored as binary data. The registry editors displays this information in hexadecimal.
REG_DWORD.	The data is presented as a value, the length of which is 4 bytes. This type of data is used by many device drivers and services. Registry editors can display such data in a binary, hexadecimal and decimal format.
REG_EXPAND_SZ.	The expandable line of the data is a text containing a variable that can be replaced when calling from the application side.
REG_MULTI_SZ.	Multi-line field. Values \u200b\u200bthat actually represent lists of text strings typically have this type of data.
Reg_sz.	The text string in the format, convenient for perception by a person. This type Assigns to the values \u200b\u200bof component descriptions.
REG_DWORD_	A 32-bit number represents the equivalent of reg_dword. The youngest byte is stored in memory first among.
REG_DWORD_	A 32-bit number represents the equivalent of reg_dword. The oldest byte is kept in memory first among.
REG_LINK.	Symbolic link Unicode. This data type is intended for internal use. Data type REG_LINK allows one registry element to reference another key or parameter.
Reg_none	Does not have a specific type of data.
REG_QWORD.	64-bit
REG_QWORD_ Little_Endian.	The 64-bit number is equivalent to reg_qword. The youngest byte is stored in memory first among.
REG_QWORD_ Big_endian.	The 64-bit number is equivalent to reg_qword. The oldest byte is kept in memory first among.
REG_RESOURCE_LIST.	List of hardware resources applied to branches HKEY_LOCAL_MACHINE \\ HARDWARE.
REG_FULL_RESOURCE_	The descriptor (descriptor) of the hardware resource is used in the branch HKEY_LOCAL_MACHINE \\ HARDWARE.
REG__Resource_	The list of necessary hardware resources is used in the branch HKEY_LOCAL_MACHINE \\ HARDWARE.

The registry is divided into components that developers called the hives (Hives), by analogy with the cellular beehive cell. Beehive is a discrete structure of keys, invested keys and parameters, originating in the top of the registry hierarchy. The difference between the hives from other key groups is, they are permanent registry components. Hives are not created dynamically when the system starts and are not deleted when it stops.

The audit data registry data defining system-wide configuration parameters are stored in files that are located in the% SystemDrive% \\ Boot \\ BCD and% Systemroot% \\ System32 \\ Config directories. The area of \u200b\u200bthe registry specifying the user configuration information is stored in% Systemroot% \\ users \\ username.
