What to do if Windows does not work. The Windows button does not work on the keyboard. Problems with access to the NTLDR file

We will correct errors in Windows 10. But about the same it will be necessary to do both in Windows XP, 7 and 8. In Windows 7 and later releases, developers have improved the recovery system after problems with the launch. In the old versions of the system, serious errors more often have to solve reinstalling.

Disconnect peripheral devices

Try to remember which changes you have recently been introduced into the system: whether new, devices were installed or switched. Perhaps the problem is in one of the hardware components. Try to turn off:

1. USB drives.
2. Cardriders.
3. Printers.
4. Scanners.
5. Cameras.
6. All other external devices.

If it does not help, disconnect the keyboard and mouse: you need to exclude all possible sources of malfunction.

Also, the cause can be internal components, such as RAM. In the desktop PC, you can check the performance of the RAM, connecting the planks alternately.

Check power

If the computer does not turn on at all, pay attention to the power cable and sockets. Do not forget about the power switch on the back of the desktop housing.

If everything works on this level, but the computer does not all turn on, then, most likely, the problem in the power supply that you can hardly fix it yourself: you have to replace or repair from a specialist.

A variant is possible when the computer turns on, but only for a short time. This is the same problem with the power supply.

Adjust the system to download the system

When starting, errors may appear: An Operating System Wasn't Found. Try DisconNecting Any Drives That Don't Contain An Operating System. Press Ctrl + Alt + Del to Restart or BOOT FAILURE. Reboot and Select Proper Boot Device or Insert Boot Media in Selected Boot Device.

In the BIOS or UEFI settings, it can be downloaded from an external device or other logical partition, and not from the system disk. You can restore the default parameters like this:

1. To restart a computer.
2. Immediately after restarting, press the system key, for example F2. This may be the other key: Typically, during the system boot, it can be found at the bottom of the screen with the logo of the manufacturer's laptop or motherboard.
3. In the settings, set the desired disc to the first place in the download.
4. Select "Save and Exit" (Save and Exit) to save changes.

If the described above did not help, you will have to restore the system loader. This will require a bootable flash drive or a recovery disk with a suitable system. How to make a loading flash drive or disk, read the Windows Lifehacker.

Run the system from a flash drive or disk by selecting the desired option in the download menu. In the Windows Setup menu that opens, select "System Restore".

In the Recovery menu, select "Troubleshooting" → "Advanced Parameters" → "Recovery when loading". After that, the system will try to automatically correct the bootloader. In most cases, it solves the problem.

You can do the same manually through the command line, but it is better to choose an automatic option so as not to aggravate the situation.

If this method does not help, it is likely that the problem lies in the hardware: a hard disk is damaged.

In the Recovery menu, select "Troubleshooting" → "Advanced Parameters" → "Command Line".

In the command prompt, you need to enter alternately commands: diskpart → List Volume (Be sure to memorize the name of the disk from Windows) → EXIT.

To check the disk on errors and damage, enter the CKDSK X: / R command (where x is the name of the disk with Windows). Check usually lasts long enough, have to wait.

Run Windows in safe mode

Because of the sudden disconnection of the computer while installing the operating system updates, cleaning viruses and unnecessary entries in the registry or the fault of the Utilities to speed up Windows can be damaged by system files. In this case, when loading the system, the "blue screen of death" will appear.

Try running Windows in secure mode without downloading drivers and programs in autorun. If in this mode, the computer works, you will have to delete drivers, perform system rollback and scan to viruses.

In the presence of recovery points, this problem is solved simply enough. You just need to roll back to the previous stable configuration.

Reinstall system files

The actions described above may not help. Then you will have to reset the Windows settings and reinstall the system saving the files. Unfortunately, all programs will need to be renovated.

In the recovery environment, select "Troubleshoot" → "Reset Settings" (RESET THIS PC) → "Save My Files" (Keep My Files) → "Reset" (Reset).

The system will roll back to initial settings.

Sometimes users encounter a problem when Windows Media Player does not work, the global search for solving the problem begins. Soviets are many, but really workers are only a few pieces.

Today I will show you 3 light ways that will make MEDIA Player work in normal mode, as was originally. And as a bonus, at the end of the article, you can watch a video lesson in which the practical example shows the fulfillment of all necessary actions.

Introduction

If you are reading, then you have no longer running the standard Windows Media Player, which you have always used, and maybe you are just a curious user who wants life armed with knowledge just in case.

Therefore, before proceeding with solving the problem, I will tell you a little about the reasons for which people face this problem. After all, the majority begins to shout that they say that the virus picked up, but of course it happens, but very rare. Basically, it fails in the operating system and the media player flies the data libraries or launch keys in the registry. The situation is not very pleasant, but easily solved.

Dear readers, the main thing is not necessary to hurry, do everything in order. Do not immediately jump on the last option, because problems are different and only applying all the available steps you can restore the work of your Windows Media Playera. Let's go to the case.

Restarting media components

The easiest way to solve a problem with a non-working player is so for the reboot it, for this you need to perform a number of simple actions.

Go to the "Start" menu and select the section "Control Panel"

Now we are looking for a section "Programs and Components / Delete or Change Programs", come in:

Go to the "Enable or Disable Windows Components" section

We are waiting for a few seconds. Downloading and see a small window in which you need to find the line "Components for working with multimedia" our task to remove a tick from this row and apply the settings. Be careful, you will be prompted to restart the computer, it must be done.

After you have applied new settings and rebooted the computer, simply return to this menu once again and put the checkbox that was removed, then we try to run Windows Media Player. If the problem remains, then do not despair, just go to the next method and everything will definitely.

Re-registration of system libraries

The process is quite complex from the technical side, but in practice it is very easily fulfilled and thousands of users are used after a minute use their player in normal mode, I wish you good luck. Our task is to restore in the system libraries, for this we simply press the "Start" menu and directly in the search bar we will prescribe the command: regsvr32 jscript.dll

Next, enter two more commands:

• rEGSVR32 VBScript.dll
• regsvr32 wmp.dll

It turned out three teams that you in turn applied, the main thing is not to miss not alone, just prescribed, applied and the same with the next and with the next one. And when we finished trying to turn on your not working Windows Media Player.

As a result? Is the problem solved? I think that after that, almost all users are happy with the player without problems, but if you are still tormented, because you have some kind of special problem, then it's time to move to "heavy artillery".

Automatic recovery of Media Playera

At this stage, everything is incredibly simple, our task to go to the official Microsoft support site and find a free utility there, which should automatically test a series of problematic cases associated with the Windows Media player and immediately eliminate them.

Agree it is very cool and incredibly easy, the main thing is to help. And for this we proceed to action.

And now load the same program to your computer:

After you downloaded the utility, simply launch it and follow the clear instructions:

For those who still doubt their strength or is experiencing that it will make a mistake. Then I have already provided it and prepared for you a detailed video with practical examples, where I myself do every step in your eyes. It remains only to look and repeat on your computer. Happy viewing.

Watch video: Windows Media Player does not work, there is a solution!

After studying the entire material, please unsubscribe in the comments, did you help my recommendations in solving the problem? Does the player now earned or not? Maybe you have applied some kind of method, do not zhil, we have about a thousand people every day on this site, share your knowledge and many will be grateful to you.

Failures and refusal to work the Windows media player are not at all uncommon. To understand why Media Player does not work, you need to deal with the causes of the program failure. The most common causes of failure become:

• The Windows operating system fails;
• Viruses.

It does not matter, it is important which reason it will cause it most often to delete keys in the registry and Windows library. This may happen both by the fault of the user who installed the wrong or malware and the fault of the operational system of Windows.

As a result, we get a refusal to start and work the media player, which can be corrected in 3 ways. Immediately I want to note that these Windows Media Player restore solutions are the same for various Windows Editors: Windows XP, Windows 7, Windows 8-8.1 and Windows 10.

I think the screenshots of all available Windows in the screenshots of all available Windows is not worth it, since only an interface change in the process.

3 ways to restore the performance of Windows Media Player

Since, the reasons are different, then not each of the decisions presented can correct the performance of the media player. Therefore, each of the ways consistently checking - earned or not Media Player.

Agree it is very cool and incredibly easy, the main thing is to help. And for this we proceed to action.

And now load the same program to your computer:

After you downloaded the utility, simply launch it and follow the clear instructions:

Unfortunately, the inability of Windows is loaded - this is a problem that arises without messages about the error or any other obvious way to solve it. You may have a black screen immediately after starting, or the computer will independently restart instead or even after displaying the desktop on the screen.
Most often this is due to incorrect device drivers, errors in the system registry, destroying files and malicious programs.
What to do if Windows does not start? Before you there is no Explorer to delete files, no Internet to find some solution, no device manager, where you can disable and enable components, and there is also no solitaire to kill time while you are waiting for the end of the anti-speed program. You have only this book and the sound of your breath, distributing in silence. Fortunately, Microsoft removed the limited recovery console that was used in Windows 2000 and XP. It is replaced by a fully automatic set of tools, which will be discussed further, as well as a full-featured command line.
Launch restoration
When the tool assembling to restore Windows 7 start, Microsoft used Apple Computer Corporation: everything is simple, but so that it does not start working in the real world.
Starting the recovery is set by default Windows 7 in a separate disc section, but depending on the level of breakage you either can get there or not. Read the "Usage F8" section.
If F8 does not work, you will have to find the Windows 7 installation disk, which you may have already had to forget.
Insert the installation disk into the drive and turn on the computer. If the "Set Now" window appears, then click on the Restore Computer below. If the tip jumped up on the screen, select the Use Recovery Tools feature, select the operating system from the list and click Next.
Another option here is called the computer recovery using the system image and applies only if you used the Creating System Image tool. Be careful with this tool; You will definitely lose all the information if you choose this option.
Good news - you can fall apart in the chair and follow the pointer, about twenty minutes. Bad news - you do not have another choice.
You may be familiar with the interactive menu of five useful regenerating tools used in Windows Vista; Do not worry, they are present in Windows 7, but you need to wait. A few minutes of Windows will try to solve the problem without your help, but only in order to provide an option to start installing Windows again. Click the Cancel button to continue to look at the running black strip; Later you will be offered the best system restoration tools.
If the Windows automated tool helped solve the problem, consider yourself lucky. Otherwise, the message "Start recovery cannot restore this computer automatically" with a proposal to send a message about the problem in Microsoft; But since the Windows system does not work and connect to the network is inactive, then such a message will not go anywhere. Click Cancel to display the long-awaited page with system recovery tools. This is how these tools work:
Launch restoration
Pressing this button will return you a step back; If you have already gone so far, then this option is useless.
System Restore
This button returns Windows Back to multiple recovery points. It turns out to be useful if the last driver installation prevented Windows to start the system. Depending on how long the system of restoring the system has long happened, it can either happen anything or can return very far back. It is worth trying, but do not be surprised if it leads to a breakdown of a newly installed application or driver. Note the section "Back to the Past - use the recovery points and shadow copies".
Restoring the image image
This operation can be used to clean the hard disk and restore the backup made using the Create System Image Image tool in the control panel.
Windows diagnostics
This button will allow you to check the system memory for errors. In contrast to all other, this tool does not change anything on the hard disk, so it can be used at any time.
Command line
From all of all of the Tools listed on this page, this is exactly the one that will save your time. Use this tool to open a command-line window that allows you to copy, delete or rename files that may interfere with Windows loading. These actions are also possible in secure mode with command line support.
Use F8.
Immediately after launching a computer, but before the Windows logo appears, press F8 to start the Advanced download options menu.
If F8 does not help, then, perhaps, your computer does not recognize the installation of Windows, and the restore tool will be required to restore the Windows installation disk described earlier. If these tools do not work or you do not have an original disk, then it is best to disconnect the hard drive from the computer and connect it to another computer using a special USB tool. And then it will be possible to determine the problem, or - in the worst case, try to restore at least part of its data, as described in the section "Restoring the system after breakage".
From the menu that appears after pressing F8, you can select the following functions:
Computer recovery
If you select this option, you immediately go to the system restore parameters.
If the computer recovery option does not appear, it means that your hard drive does not contain the hidden section "System Restore" with a volume of 100 MB. If this section is not, then the Windows 7 installation disk is required to gain access to the tools.
Safe mode
In this mode, Windows works in a semi-functional state that allows you to troubleshoot or delete programs or devices drivers. If network drivers are not responsible for the Windows breakdown, use the Safety Mode with the download of network drivers instead of just a safe mode.
Safe Mode with Network Driver Download
It is practically the same as a secure mode, except that Windows downloads network drivers. This is very important if you need access to the Internet or transfer files from other computers to other computers to other computers to other computers.
Safe Mode with Command Line Support
Instead of downloading Windows and desktop you will see the command line window. It will be similar to the one that is available from the system restore parameters.
Download Option Safe Mode with command-line support is a good choice if you suspect that Windows starts prevents the recent driver installation. When the command line window appears, enter Devmgmt.msc and press ENTER to start the device manager. Then, in the Device Manager window, find the driver, right-click and disable it. Close Device Manager and restart Windows.
To exit the command line and restart Windows, enter the EXIT word and press ENTER. If, after entering the word Exit, the command line window closes, but Windows remains to work, press Ctri + Alt + Del, and then on a small arrow located next to the red button at the bottom of the screen. To resolve file errors on the hard disk, refer to the "Disk error search" section.
Logging logging
This option launches Windows in the usual way, except that each boot step is recorded in the NTBTlog.txt file, which is located in the \\ Windows folder. If Windows does not start, start it by selecting the download logging, at least once. Then restart the computer, press the F8 button again and select one of the secure mode options previously listed. When you enter Windows again, read the record using a notepad; It is likely that the last entry in the protocol contains information about the source of the problem.
Low resolution video mode
This option launches Windows in the usual way, but in VGA mode. It helps to detect non-working drivers or incorrect video equipment settings, running Windows in the most compatible display mode.
Loading the last successful configuration
This option launches Windows with that configuration of drivers and settings of the system registry with which the system has been successfully loaded earlier. Use this option if a problem that does not allow Windows to start work has led to recent changes in the system registry or hardware installation. Check out the section "Back to the Past - use recovery points and shadow copies".
Directory Recovery Recovery Mode
If your computer is a network domain controller, which, strictly speaking, is impossible in Windows 7, this option disables Active Directory. In other words, in Windows 7, you will not be able to use this method.
Debug mode
In this mode, usually not intended for end users, information about correcting the problem is sent to the serial port for writing it with another computer. But in general, is there a serial port on your computer?
Disable automatic reboot when system fails
Unlike the remaining eight options, this simply changes the settings so that you can determine the cause of the Windows invasion. If the failure occurs during Windows loading, then by default, the computer restarts so quickly that it is impossible to read an error message on this notorious blue screen. Disconnect the automatic reboot when the system fails if you want to read the message, and then restart the computer manually.
Disable forced signing drivers
By default, the 64-bit edition of Windows 7 will not allow the installation of any drivers on which the electronic signature was not supplied.
You can disable the forced signing of the drivers so that the computer can install drivers that do not have signatures, but in practice it never works. Instead, you should open the command prompt window and enter the following:
bcdedit.exe - set LoadOptions ddisable_integrity_checks
Press the ENTER button, close the command prompt window and restart Windows to get the desired result. If it does not work, then you may have to give up support for certain devices until the manufacturer does for them signed and "native" driver.
The name of this option speaks for itself - use it to continue the usual boot of Windows, as if you never pressed F8. With these tools you will get everything you need to run Windows again.
