. Windows 7 has been released for several months. In combination with the gorgeousness of Vista, the stability and speed of XP, Windows 7 has gained a good reputation since the beta version. As a result, more and more windows xp users have changed to use win 7. However, after using the win7 system, many times we will find more and more system problems. If it will be used, the system will not operate efficiently. It's very high, and it doesn't even work. If you choose to reinstall the system, it will not only be troublesome, but it will also take a long time to 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", the damaged Windows system may have a miraculous effect. !
1, the last configuration
Windows2000 or higher version of the operating system, after each successful startup will automatically back up the system registry, once we find that the Windows system can not start properly this time, it is mostly on us The wrong operation of the system or the wrong installation of some software was performed, 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 the Windows system are accidentally damaged, then even if you use "last configuration", Windows system is difficult to guarantee that it will start normally. 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 only caused by improper software installed or improper settings of the software, then we can usually log out the current user by “ ” method to give first aid to the damaged Windows system, because the impact of the software on the system settings can only be limited to the currently logged in users, once the system can not run normally in the current user state, we can completely cancel the current user, And log in to the system with other users, so that Windows can generally resume normal operation.
Before logging out the current user and switching to other users 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 “Add” in the interface. Button to re-create 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. For this reason, before logging out the user, we need to open the system explorer window to find the current account. The corresponding user directory, 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 is backed up to the system partition. In a partition other than the directory.
After doing the above preparations, we can now execute the "start”/“logout aaaa ” command to log out the current login account and then log in again with the account just created. Windows system; after successfully logging into 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 running state. .
4, re-register DLL files
Windows system is sometimes subject to frequent damage, mainly because many applications often share calls to some DLL files, once some applications are automatically uninstalled after use, these applications The DLL files called by the program 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 case of the Windows system running abnormally caused by the loss of the system DLL file, we do not need to re-install the operating system, just need to re-register the DLL files that have been lost, the system can be restored to normal operation. It is. 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 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 I assume that 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's desktop. When you need to re-register all the DLL files in the system in the future, we only need to double-click the shortcut icon of the repair.bat file to automatically start all the DLLs. The file performs a re-registration operation. 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!
