core prompt without reloading: Many times we will find more and more system problems, if it will be used, the system operation efficiency will not be very high, and even can not run normally. 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 don't... many times we will find that our system problems are getting more and more. If we use it, the system will not run very efficiently. Even if it doesn't work properly, 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 to start or run an error, we may wish to use the following six measures to quickly and effectively "first aid", the damaged Windows system, may be able to harvest the miraculous effect!
1, the last configuration
Windows2000 or higher version of the operating system, each time after successful startup will automatically back up the system registry, once we find that the Windows system can not start normally this time, then most of us last time The system has been wrongly operated or some software has been installed incorrectly, thus destroying 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 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 “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. For the corresponding user directory, for example, if the current login system account is aaaa, then the system default account directory should be “C:\\Windows\\Documents and Settings\\aaaa”, and some important data below the directory is backed up to In 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 log in to Windows with the account just created. 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, when the Windows system is not working properly due to the loss of the system DLL file, we do not need to reinstall the operating system at all. We only need to re-register the DLL files that have been lost, so that the system can be restored. 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 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 repair.bat file. Icon, the system will automatically start re-registering all 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 copy the original registry information directly Go to the corresponding directory of the system, this can quickly achieve the purpose of recovering damaged system files. 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 can be:
If the local computer only has one operating system installed, then we may wish to use the Windows 98 boot CD to boot the system to the DOS command line state; if more than two operations are installed on the local computer System, then you only need to switch the system to another system that can run normally; then in the DOS command line state, use the CD command to switch the current directory to the "%windir%\\Repair" subdirectory state. And execute the following string command in sequence:
copysam%windir%\\system32\\config
copysystem%windir%\\system32\\config
copysoftware%windir%\\system32\\config
copydefault%windir%\\system32 \\config
copysecurity%windir%\\system32\\config
Once in the process of executing the string command above, When the pop-up prompt asks whether to overwrite the previous file, we can directly answer the answer. After the system registry information is replaced by all the original registry files, we restart the system again, I believe the system will be able to run normally.
6, system restore function
If we install Windows XP system in our computer, then in addition to the above method to rescue the damaged system, but also with the Windows XP system-specific "system restore function" ;, to restore the operating state of the Windows system to normal, the following is the specific implementation steps of the method:
Click “ Start & rdquo; /& ldquo; Programs & rdquo; /& ldquo; Attachments & rdquo; /& ldquo; System Tools ” /& ldquo; System Restore & rdquo; command, in the system restore settings wizard interface that pops up, will "restore my computer to an earlier time" project selected, and then click "Next" Button; in the system restore point list window that pops up later, we generally select a restore point that is closer to the current time to restore the system. Once the target restore point is selected, continue to click the “Next” button. The Windows system can be automatically restored to its previous normal working state. It is worth mentioning that before using this function, we must create a suitable system restore point in time when the Windows system is running normally, so that it can be used in future recovery of the system!
