It is always important to ensure the safety of your laptop or tablet. Microsoft began seriously referring security after a rather rough bug in Windows XP. Only in Windows 8 and Windows 10 Microsoft included a tool to detect and correct errors on your devices.

Using Windows 8 and Windows 10, you automatically get free antivirus defense. Moreover, you do not need to independently manage your updates or download them from the website. They operate autonomously and efficiently, ensuring the safety of your device as much as possible. Microsoft calls its set of antivirus windows Defender.

Here's how to scan viruses in Windows 10 using Windows Defender., Safety program built into each new laptop, tablet and desktop with the latest Microsoft 2-B-1 operating system.

It may be a refund or laptop to its original state.

Or rollback to the previously created point of recovery.

In addition, there are options for creating images and recovery disks, for full or partial conversion of the system status.

Utility MWFIX

Runing the MWFIX utility, the user will access the mass of built-in tools for elimination of various mistakes arising in the system.

Fixwin program

Fixwin 10 represents set of toolsaimed at solving the majority of failures and problems that occur in the work of the tenth version of Windows.

Functional and opportunity

You can download WinFix on the official developer website: http://www.thewindowsclub.com/fixwin-for-windows-10

All tools and utilities included in the program are divided into several sections, each of which is responsible for a separate category Labor:

Here in each of them is more than a dozen typical cases or their whole group by selecting the most appropriate option, you should click on button "Fixยป , that is, "fix" and the program will automatically do everything.

Considering the fact that the program is not Russified further will be presented in detail all sections separately with the translation of error categories.

Section File Explorer

This section is dedicated directly conductorWindows and is responsible for problems with labels, display of elements, etc.

Internet & Connectivity

Most of the items of this section concern note S.Internet Explorer.which is now practically not used. Thus, other items that do not concern IE will be presented below.

Section Windows 10.

This is one of the most demanded sections that contains a lot of useful functions.

System Tools.

This toolkit comes to help in those difficult moments when the main system tools And the assistants for one or another reason are not available in the traditional ways.

Troubleshooters.

This section makes it possible to produce scan computer For violations of a certain type. It may be faults, both hardware and software.

Additional Fixes.

Obviously, here you can find everything that is not included in the previous sections either does not have a strict classification.
This is the least demanded section among others.

Common mistakes

In the course of the work or launch of WIN10 OS, all sorts of problems are not uncommon. Of course, to correct the situation, one after another is updated and patches. You can still determine the whole list the most common Situations:

  • errors with updates;
  • drivers;
  • hardware failures;
  • registry malfunctions;
  • problems with launch.

Of course, this is not a complete list. Most problems are identified by their own code, which allows them to quickly identify and take the necessary actions.

Errors when loading the system

Windows 10 users sometimes when loading a computer can face blue or black screen. This is system failurecaused by any error. Often the code, name, or the number of the breakage is given in the same window, which allows the user to receive more information about the specific situation regarding the causes of its occurrence and ways to eliminate. Since the reason can be wounded both in hardware and software problems, ways to solve the problem In each case, there may be different.

MEMORY MANAGEMENT error

It occurs after installing a new software or hardwareor or in the very installation process. In general, the causes of error such as Memory Management may be caused by a number of problems in firmware, equipment, drivers or by software.

Error with code 10016

In the journal windows events 10 After the system starts, it may occur with the code 10016. This is a system event that indicates the impossibility of running Specific application by a specific service. To eliminate it, you will need manual editing system registryIt is not recommended to make inexperienced users.

NetWlv64 error

NetWlv64.sys may be present in the operating system as a driver third-party device either one of the important system files.

Errors like this type occur when equipment malfunctions Or the file itself and they are issued when trying to start a computer, program, or a separate function. Reinstalling and updating drivers should save the user from this problem.

ActiveX / COM error

A fairly widespread error that is associated with problems in the registry. Most often arises at the first time of the new operating system, while its registry is not yet stable. Eliminated easily with programsCCleanerUsing the scan function and repairing the registry.

Code 31.

The main source of this error is any damage or conflict in Drivers. Among the additional reasons are subject to registry damage, and other system files under the influence of malicious elements. As a rule, Code 31 is eliminated by restoring the system.

Error with code 80073712

This error is related to the update center and occurs, as a rule, during the installation of new components.

This is pure system errorwhich arises due to disorders of workability Update repository. Eliminated using the PowerShell system utility.

Often, users are forced to believe that the system files of the operating system (OS) are damaged, the reason in the characteristic failures when performing elementary operations and slow operation of the computer. It happens that loading an external IT product leads to a destructive change in the OS configuration. In these cases, it helps to check the integrity of system files in Windows 10.

Usually, two are provided software products SFC.exe and Dism.exe, and, in addition, the REPAIR-WindowsImage command for Windows PowerShell. The first check the integrity of the components of the system and automatically restore their identified defects. The second does this using DISM.

Experts are confident that it is more expedient to use them alternately, since the lists of the scanned files from these software differ from each other.

In continuation, consider several instructions for the use of the software presented. The actions described are safe, however it is necessary to remember that the recovery of system files is complex in nature, and even the changes that are entered by the user. In particular, the installation of external resources and other OS transformations will be canceled.

Investigation of the system integrity and correcting its elements using SFC

The SFC / SCANNOW OS integrity scan command is popular among experienced users. It automatically examines and eliminates the defects of the components of the OS.

The operation of SFC is carried out on behalf of the administrator, through the command line, which opens the right click on the "Start" menu. Next, the SFC / SCANNOW is entered and "Enter" is pressed.

These actions begin to check the OS, as a result of which the identified damage is corrected. In the absence of errors, the user sees the message "Protection windows resources did not find integrity disorders. " Another aspect of this study is unreasonable damage. They will be devoted to a part of the continuation of this article.

The SFC / ScanFile \u003d "Path_Fail" command allows you to check for errors in a specific system component.

The disadvantage of the software is that it does not eliminate defects of OS elements used during scanning. The problem is solved by the launch of SFC via the command line in the OS recovery environment. This method is quite effective, and implies the execution of several simple operations.

Integrity Investigation using SFC in OS Recovery Environment

It does not take much time, and does not imply special skills. The launch in the OS recovery environment is performed in several ways:

  1. You need to enter the "Parameters" and alternately select "Update and Security", "Restore", "Special Download Options" and "Restart Now". A simpler method: in the bottom right part of the input interface in the OS, the "On" label is pressed, after which, holding the "SHIFT", you must click "reboot".
  2. Another option is to load from a pre-prepared OS recovery disk.
  3. Another alternative is an electronic medium with an OS distribution. In the installation program, after selecting the language, the "Restoration of the system" is selected in the left lower part.


At the end, you must enter the "Troubleshooting", select "Advanced Parameters" and press the "Command Line" (the use of the first of the previously presented methods implies the system administrator password). Next, the following is sequentially:

  • diskpart.
  • list Volume


Following the start of the specified commands, the user sees the volume list. It is recommended to remember their designations corresponding to the disk "reserved by the system" and partition from the OS, since sometimes they differ from those that are in the conductor.

sFC / SCANNOW / OFFBOOTDIR \u003d F: \\ / offwindir \u003d C: \\ Windows (where f - the previously specified disk "Reserved by the system", and C: \\ Windows is the path to the OS folder).


The actions described initiate a deep study of the system integrity during which the SFC command corrects all damaged components, without exception. Study may take a long time. The underlining indicator, Merzay, shows that the system continues to work. After completion, the command line is closed, and the OS is rebooted in standard mode.

Scanning and Restoring System Using Dism.exe

It happens that the SFC command does not cope with some defects system components. It-product Dism.exe allows you to finish the started recovery. It scans and serves the system, correcting even the most problematic components.

Dism.exe is used even when SFC does not reveal the defects of the integrity of the OS, and the reason to suspect that they are preserved.

First of all, the command line starts with the right click of the mouse on the "Start" menu on behalf of the administrator. Then other commands are launched:

  • dISM / Online / CleanUp-image / Checkhealth. It is used to form information about the state of the OS, the presence of damage to its components. It does not initiate the study, scans earlier values \u200b\u200bof fixed parameters.


  • dISM / ONLINE / CLEANUP-Image / SCANHEALTH. Explores and checks the integrity of the repository of system components. It takes a lot of time, with difficulty overcoming a level of 20%.


  • dISM / ONLINE / CLEANUP-Image / RESTOREHEALTH. Explores and automatically restores OS. It works slowly, sometimes interrupting.


In circumstances, when the recovery of the system elements is not implemented, Install.wim (ESD) is used with Windows 10 ISO as the source of the corrected components. For this purpose, another option is applied:

dISM / Online / CleanUp-image / RestoreHealth / Source: WIM: Path_Fail_Wim: 1 / Limitaccess

In some cases, ".wim is replaced by N.Sd."

While using these commands, all operations running are saved in a log, which is contained in Windows \\ Logs \\ CBS \\ CBS.log and Windows \\ Logs \\ DISM \\ DISM.log. The DISM tool starts in the OS recovery environment as well as this happens when SFC is running.

it software It is also implemented in Windows PowerShell on behalf of the administrator, using the set of Repair-WindowsImage commands. For example:

  • REPAIR-WindowsImage -online -scanhealth. Looking for defects of system elements,
  • REPAIR-WindowsImage -Online -restoreHealth. Explores and eliminates faults.

Apparently, the restoration of the integrity of the OS is a completely executing task, the solution of which allows you to get rid of a variety of problems with the system. In rare cases, when the tools described do not help, you should use other algorithms located in open access. In particular, you should try to roll back the system until the same point windows restoration 10.

Some users face that SFC detects defects of system elements immediately after the update with the new assembly of the OS. Under these conditions, the error correction is possible only with a new "clean" setting of the system image. Sometimes damage is detected from individual versions software For video cards. At the specified case, the erroneous is the OpenCl.dll file. Perhaps in these circumstances should not be taken at all any actions.

Conclusion

The described methods for studying the integrity of the OS is simple and effective. The stages of their implementation are understandable to most of the user's audience, including those who do not have special programming skills. However, to secure the material, it will be useful videos in open access to the World Internet.

Whenever something goes wrong with a computer or laptop, there are a number of tools for troubleshooting that you can perform to try to eliminate the problem. In Windows 10/8/7 there are several built-in commands that can be used to check and restore damaged system files that eventually cause problems when changing. One of the ways to troubleshoot problems associated with Windows is to check the system and restore system files. It can help in all types of problems such as a slow system, blue screen Death, sudden power failures and system failures.

Consider how to run the system file verification tool in Windows using cMD command line and PowerShell., such teams as sFC / SCANNOW. and tools DISM. I want to notice that for updating Anniversary Update. Windows 10 will better use methods from PowerShell.

Check and restore system files via CMD

The system file verification tool scans your computer for any damage or changes in system files that could otherwise interfere normal work Your PC. From there, he replaces the file with the correct version to ensure uninterrupted operation. Using the command line, you can try to scan and restore the Late System Files operating systemslike Windows 10/8/7 / Vista. We will examine two teams sFC / SCANNOW and DISM Using CMD.

1.

  • Run the command prompt (CMD) on behalf of the administrator. Click "Search" and write simply "CMD" or "Command Line", then on it right-click and launch on behalf of the admin.
  • Set the command sFC / SCANNOW.and wait for the end of the process.


Note:After scanning your system, one of three results will be issued:

  • System file errors will not be.
  • There will be errors of system files and Windows will restore them automatically.
  • Windows has detected errors, but cannot restore some of them.

If you feature option 3, that the error is detected and the system cannot recover, then do the procedure. I advise you to disable encryption and, if at the time of the check they are available. Nothing succeeded? Moving below.


2. (DISM)

If the above does not work in safe mode, there is one last method Check damage in system files and fix them. Use the Deployment Image and Service Management (DISM) tool. The command works S. windows systems 8/8.1 / 10. Open back and use the following command:

The process can take a long time with the percentage of the percentage scale. Having finished working, restart the computer and run back sFC / SCANNOW, To make sure that there is no error or the error disappeared.


Check and restore system files throughPowerShell.

We will use Windows PowerShell to show how to use service and management service DISM. For scanning and correcting damaged system files in Windows 10. This method will be more efficient to update Anniversary Windows 10 than the command line.

1. Using the SYSTEM FILE CHECKER (SFC) tool

  • Launch PowerShell. On behalf of the administrator. Click "Search" and type Windows PowerShell, after right-click and select on behalf of the admin.

  • Set the command in the PowerShell window sFC / SCANNOW.If scan detects any problems, Windows will try to fix them. If Windows cannot fix them, he will warn you that further research and actions are needed. Move below if errors are detected.


2. Using the Deployment Image and Service Management tool (DISM)

DISM scan detects corrupted system files and Windows will try to fix them, and will give you a progress report at the end. If Windows cannot find the files needed to restore damaged system files, you will also be provided with information about what to do next, with reference to the Microsoft website and troubleshooting options. Set the command below to the PowerShell window.

DISM / ONLINE / CLEANUP-Image / RESTOREHEALTH

If DISM fixed it or did not reveal the errors, then restart the laptop, computer and run to check back sFC / SCANNOW.
