Deleting is safe. You can't delete it indiscriminately. That will make the system unstable. Try the following methods, but be patient for a long time.

1, system restore is disabled, it will be restored after encapsulation, and it will not affect;

2. Transfer paging file (virtual memory), which can be transferred to disk D or disabled, but it will be restored after encapsulation. Ghost8.0 can directly block this big guy;

3. Transfer the temporary folder. D: \ temp is recommended;

4. Disabling hibernation can save as much space as memory;

5. Transfer the temporary folder (cache) of IE to D: \ temp; The storage location of OE is changed to d: \ my documents \ OE;

6. Relocate my document and recommend D:\ My document.

7. Optionally uninstall unnecessary windows components. Enter "%systemroot%/inf/sysoc.inf" to open this file, click "Replace" under the Edit menu in Notepad, then enter "Hide" (without quotation marks) in "Find what", then click the "Replace All" button on the right, then save the file and close it. Reopen Add and Remove Programs in Control Panel, and then click Add and Remove Windows Components. Now you can directly uninstall many components that were not allowed to be uninstalled before. Please use it with caution;

8. Close the memory dump. In the System Properties dialog box, under the Advanced tab, click the Start and Resume button, and then select None from the Write Debugging Information drop-down menu. And you can search all *. Dmp files and delete them. At the same time, enter "drwtsn32" during the running process, and press Enter to open the tool of Dr. Watson, in which the selections of "Dump all thread contexts", "Append to existing log file" and "Create fault dump file" are cancelled.

9. Delete large Chinese fonts. Generally, it is enough to keep the Song style (including the one in 18030), bold and imitation Song style.

10, delete system file backup, which is dllcache. At runtime, enter "CMD" and press Enter to open a command prompt window, and then enter "sfc /purgecache" and press Enter, which will delete all the backup files in the aforementioned c:\windows\system32\dllcache folder, and then continue to enter "sfc/cache = 0" and press Enter. A windows file protection box may appear.

1 1. windows file protection is prohibited. Look up from the registry

HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ Current Version \ Winlogon, change the key value of "SFCDisable" to "FFFFFF9D", and reset it to "0" if you need to re-enable this function.

12. Delete the help file. Delete the "Help" folder in the Windows directory directly, but it's best to keep a few: agt0407.hlp digital format, or you may need to pack the started source CD, anyway, it's only a few k, so keep it.

13, redundant input method. This cannot be completely deleted, or you will be prompted to insert the source CD after packaging! In addition to Chinese input methods, Windows XP also has Japanese and Korean input methods, which is of course useless to us. We can also selectively delete the contents of other folders except "CHSIME" and "SHARED" under the "c:\windows\ime" folder. The result is as shown in the figure:

Especially imjp8_ 1 and imkr6_ 1 need to keep folders and some dll files. If they are not very big, try to keep them. After deleting ime, it can be reduced from more than 80 m to 2.36m m..

C:\windows\ime saves a file list.

│ mscandui.dll

│ SOFTKBD.DLL

│ SPGRMR.dll

│ SPTIP.dll

├—CHSIME

│ └—APPLETS

│ PINTLCSA.DLL

PADRS404.DLL

padrs4 1 1.dll

padrs4 12.dll

padrs804.dll

14. You can choose to delete the Service Pack backup file. Service Pack is a big patch file for Windows. After installing the Service Pack, the hard disk will take up some space to save the backed-up system files. You can delete the "ServicePackFiles" folder under windows.

15, reduce the time to start the scroll bar. Every time you start Windows XP, the blue scroll bar has to go many times. In fact, we can also reduce its scrolling time here to speed up the startup. Open the registry editor, find HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ prefetch parameter, find the EnablePrefetcher key on the right, and change its default value of 3 to 1, so that the scrolling time of the scroll bar will be reduced. Then go to the C:\WINDOWS\Prefetch directory and delete the contents.

16. Delete all $ ntuninstallq * * * * (* * * * is a number) files under windows;

17. You can choose to delete all files except Driver.cab and sp 1.cab in the "Driver Cache/i386" folder. Never delete these two, or the packaged system will be in trouble.

18, delete c:\windows\cursors\, this folder contains all mouse pointers;

19. delete c:\ windows \ srchast. This folder stores the search assistant of Windows XP, that is, dogs or other characters that appear when you search files. You can delete this folder directly, so you will use the classic search method of Windows 2000 mode; It is recommended to delete!

20. you can choose to delete c: \ windows \ downloaded installations \. This folder stores installation files of some programs (mainly programs installed by using Windows Installer technology), so that if this program needs to be repaired or other operations in the future, it can be done directly through the installation files saved here. However, emptying this folder usually does not have much impact on the use of the system, and it is recommended to delete it.

2 1. You can also delete c:\windows\media\ to save the system sound of windows. Do not delete unless absolutely necessary; 22. you can choose to delete c:\windows\system32\usmt\. This folder contains files for installing the transfer wizard and related files.

23. You can choose to delete c:\program files\msn and c:\program files\netmeeting\, which are MSN Explorer.

And Netmeeting executable files. It is not recommended, because the pre-installed system may use the dll file of msn4.6 when creating a new user. Although it will not affect the system, because 6. 1 has been installed or someone does not use msn, it may prompt that the lack of files is uncomfortable.

24. delete c: \ windows \ system32 \ oobe-it is suitable for enterprise version, retail version or OEM version, and it is best not to touch it.

25. you can also delete the c:\ windows \ ms Agent that saves the proxy file. Like the Office assistant in Microsoft Office application, the agent here is a dynamic cartoon image, and we usually don't need these things. Pay attention to save all agt0407.dll-like dll files in intl directory.

26. optionally clean the desktop in C:\WINDOWS\Web\Wallpaper, and you can replace it yourself. If you want to go deeper, delete the screen saver, C:\WINDOWS\system32\*.scr.
