Emergency rescue damaged Windows system

Many times we will find more and more problems with our own system. If it is used, the system will not operate very efficiently, and it will not even function properly. If you choose to reinstall The system, not only does not bother to talk, but also takes a long wait time. 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 time you configured the operating system of Windows 2000 or later, the system registry will be automatically backed up after each successful startup. Once we find that the Windows system cannot be started normally this time, most of the time we made the wrong system. The operation or the wrong installation of some software has 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 can 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, log out the current user If the damaged part of the Windows system is only due to the installation of inappropriate software, or the software is not properly set up, then we can usually "delete the current user" method by 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 is not working properly under the current user status, we can completely log out the current user and re-create it with other users. Log in to the system so that Windows can resume normal operation. Before logging out of the current user and switching to other users to log in to the system, we need to open the system's control panel window, then double-click the "User Accounts" item, and then click the "Add" button in the subsequent interface. To re-create a new login account, set a suitable access password for the account, and set the corresponding account as super administrator. After logging in to the Windows system with another account, some important data stored in the current user directory may not be accessible. For this reason, before logging out the user, we need to open the system's resource manager window to find the current account. 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 some important data below the directory will be backed up to other than the system partition. In the partition directory. After doing the above preparations, we can now execute the “Start” "Start”/“Logout aaaa” command to log out the current login account, and then log in to the Windows system with the account just created; After successfully logging into the Windows system with the new account, we will 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-registering 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, the DLL files called by these applications It is often deleted as well, so 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 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 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, and the system will open automatically
