How to urgently recover damaged Windows system

A lot of times we will find more and more problems of our own system, if you will use it, then the system will not run very efficiently, and even can not run normally, if you choose to re Installing the system is not only troublesome, but it also takes a long wait. In fact, when the Windows system encounters a failure that cannot be started or runs incorrectly, we may wish to use the following six measures to quickly and effectively "First Aid" damaged Windows system, maybe it will gain miraculous effects!

1, the last configuration

Windows2000 or later operating system, the system registry will be automatically backed up after each successful startup, once we find that the Windows system can not start normally this time, Most of that was the last time we made a wrong operation on the system or made a wrong installation of some software, which destroyed the relevant settings of the system registry. At this point, we can try to restart the computer system with the last successful startup configuration: just press the F8 function key in time to restart the system, call up the system boot menu, and then select “ last time correct The configuration of the project, in this case, the Windows system may be able to start normal.

2, repair system files

If some of the core files of Windows system are accidentally damaged, then even if you use “last configuration, Windows system is difficult to guarantee Startup is normal. If the Windows system only has a small number of system files damaged, then we may wish to use the built-in SFC scan repair command of Windows system to try to repair the damaged system files. Once the repair is successful, the Windows system starts again. Will return to normal. When repairing damaged system files, just click the “Start” and then “Run” dialog box. In the pop-up system run dialog box, enter the string command “sfc/scannow” and click the Enter key. After that, the command program will search and scan the system files at every corner of the system. Once the system file is found to be incorrect or the system file is damaged, it will automatically pop up a prompt interface, asking us to insert the Windows system. A CD-ROM is used to extract normal system files to replace abnormal system files, thereby achieving the purpose of repairing system files. If the system repair operation is successful, I believe that when we restart the computer system, we will not see any abnormality.

3. Logout of the current user

If the damaged part of the Windows system is caused by improper software installed or improper settings of the software, then we can usually First aid to the damaged Windows system by "delete the current user" method, because the impact of the software on the system settings can only be limited to the currently logged in users, once the system is not working properly in the current user state, we It is completely possible to log out of the current user and log in to the system as another user, so that Windows can generally resume normal operation.

Before logging out the current user and switching to another user to log in to the system, we need to open the control panel window of the system, then double-click the “User Account” item, and then click “&ldquo” in the interface. Add the ” button to recreate a new login account, set a suitable access password for the account, and set the corresponding account as super administrator.

Because you use another account to log in to the Windows system, some important data saved in the current user directory may not be accessible. Therefore, before logging out the user, we need to open the system explorer window. Find the user directory corresponding to the current account. For example, if the current login system account is aaaa, then the system default account directory should be “C:\\Windows\\DocumentsandSettings\\aaaa”, and all important data below the directory should be backed up. Go to a partition directory other than the system partition.

After doing the above preparations, we can now execute the "start”/“logout aaaa” command to log out the current login account and then re-create it. The account is logged in to the Windows system. After successfully logging in to the Windows system with the new account, we restore the important data backed up to the new user directory corresponding to the current account, so that the damaged Windows system can restore the previous normal operation. The state is gone.

4, re-registering DLL files

Windows systems are sometimes subject to frequent damage, mainly because many applications often share calls to some DLL files, once some applications are automatically used After uninstalling, the DLL files called by these applications are often deleted, so that when the Windows system or other applications in the system call the shared DLL files again, the error will naturally occur. .

In the first aid, when the Windows system is not working properly due to the loss of the system DLL file, the IT knowledge base believes that we do not need to reinstall the operating system at all, just need to carry out the DLL files that have been lost. Re-registering will bring the system back to normal operation. Considering that we don't know which DLL file is damaged or lost, we can use the following method to re-register all the DLL files of the system, instead of needing to be alone or Several DLL files are registered:

First open a file editing program like Notepad, and then enter the following command line code in the corresponding program interface:

@echooff

for%1in(%windir%\\system32\\*.dll)doregsvr32.exe/s%1

Save the above command line code as a batch file with the extension BAT, for example here Suppose the code content is saved as a repair.bat file; secondly, create a shortcut icon for the repair.bat file, and drag and drop the shortcut icon directly to the system desktop, and then need to re-register all the DLL files in the system in the future. When we just need to double-click the shortcut icon of the repair.bat file, the system will automatically start re-registering all the DLL files. Once all the DLL files have been re-registered, we may try to run the Windows system again. I believe the system will be very normal at this time!

5, restore the original file

If the failure of the Windows system is not normal due to the system registry was accidentally destroyed, then we can use the regular copy command to the original system The registry information is directly copied to the corresponding directory of the system, so that the purpose of recovering damaged system files can be quickly realized. Since the Windows system is successfully installed for the first time, the original registry information will be automatically saved to the Repair subdirectory under the system installation directory, so we only need to copy the registry information under the Repair subdirectory directly to the system configuration. The directory is fine:

If the local computer only has one operating system installed, then we may wish to use the Windows98 boot CD to boot the system to the DOS command line state; if there are two installed on the local computer For the above operating system, you only need to switch the system to another system that can run normally. Next, in the DOS command line state, switch the current directory to the "%windir%\\Repair" subdirectory status via the CD command. Next, and then execute the following string command in order:
