Recover damaged Windows xp system files

If Windows XP system files are damaged by viruses or other causes, we can recover the damaged files from the Windows XP installation disk.

Specific Method: Search for damaged files on the Windows XP installation disk. Note that the last character of the file name is replaced by the bottom line "_". For example: if you want to search for “notepad.exe, you need to use "Notepad. ex _ "to search.

After searching, open the command line mode and enter "cmd" in "run"), and then enter "full path of the EXPAND source file to the full path of the target file ". For example:

 
 

  
  
EXPAND D:\SETUP\NOTEPAD.EX_ C:\Windows\NOTEPAD.EXE 
 
 

. Note that if the path contains spaces, you must enclose the path in double quotation marks.

The search is of course the best, but sometimes we cannot find the files we need in the Windows XP drive. One reason for this is that the file to be searched is in the "CAB" file. Because Windows XP regards "CAB" as a folder, for Windows XP, you only need to drag the "CAB" file right and copy it to the corresponding directory.

If you are using another Windows platform, search for the "CAB" file containing the target file name. Then, in command line mode, enter "full path of the CAB file in the target location of EXTRACT/L", for example:

 
 

  
  
EXTRACT /L C:\Windows D:\I386\Driver.cab Notepad.exe 
 
 

. As before, if there is space in the path, you need to use double quotation marks to include the path.

Reject "group similar Taskbar"

Although the "Group similar taskbar button" setting in Windows XP can keep your taskbar clean, it is inconvenient for you to open multiple Windows of the same type ,. If you often use communication software such as QQ to chat with people online, if more than two friends talk to you at the same time, you will immediately feel the inconvenience caused by default settings such as xp d every time you want to switch the conversation object, you need to first click the group, and then select the friend you want to talk to in the pop-up menu, in addition, each friend shows the same icon in the group.

When there are many talking objects, you may need to click one by one to see who answered the question just now. You have to start from the group after selecting the wrong one, very troublesome. Obviously, it is better to open several windows in the original way. In each small window in the taskbar, you can click once to start chatting. Change Method: Click Start> Control Panel> appearance and topic> taskbar and Start Menu. In the displayed window, remove the hooks before the "Group similar taskbar button" option.

Unmount useless dynamic links through the Registry

Resource Manager often leaves useless dynamic links in the memory. to eliminate this problem, you can open the Registry Editor and set the key value:

 
 

  
  
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\EXPlorer\ 
 
 

AlwaysUnloadDLL = DWORD: 1 sets it to 0, and this function will be disabled. Note: To make the settings take effect, restart the computer.

When Windows XP is used for a period of time, the files in the pre-read folder will become very large and there will be dead chain files in it, which will slow down the system time. Suggestion: delete these files regularly. Windows \ prefetch)

Windows XP diet

The following methods are relatively safe and effective, and can reduce the space by at least MB. Note: It is not recommended for beginners.

Delete the Driver backup: the Driver. cab file in the Windows \ Driver cache \ i386 directory is 73 MB. However, we must insert a Windows installation CD every time we install new hardware.

Delete system file backup is generally not used): run the command line sfc/purgecache

Delete the backup dll file: If you have copied the installation file or installed a CD, you can do this. Windows \ system32 \ dllcache file minus 200 -- 300 mb ).
