Really can't, just in safe mode:

1. Open my computer-Tools-Folder Options-View-Check the "Show all files and folders" option-OK.

2. Delete the contents of the following folder:

All files under x: \ documents and settings \ user name \ cookies \ (keep index files)

All files under x: \ documents and settings \ user name \ local settings \ temp \ (user temporary files)

X: All files (page files) under \ Documents and Settings \ User Name \ Local Settings Temporary internet Files.

All files under x: \ documents and settings \ user name \ local settings \ history \ (history)

X: all files under \ documents and settings \ user name \ recent \ (shortcuts to recently browsed files)

X: all files under \ Windows \ temp \ (temporary files)

X:\WINDOWS\ServicePackFiles (backup files after upgrading sp 1 or sp2)

Compressed file under x:\WINDOWS\Driver Cache\i386 (backup file of driver)

All files under x: \ Windows \ Software Distribution \ Download.

3. If the system has been upgraded by windoes updade, please delete the following files:

Hidden files starting with $u ... in x:\windows\

4. Then defragment the disk, and please quit all running programs during defragmentation.

5. After defragmentation, open Start-Programs-Accessories-System Tools-System Restore-Create a restore point (it is best to use the current date as the name of the restore point).

6. Open my computer-right-click the system disk-Properties-Disk Cleanup-Other options-click Cleanup in the System Restore bar-select Yes-OK.

7. After all kinds of software and hardware are installed properly, XP rarely needs to update files. Delete the system backup file: Start → Run → sfc.exe/Purge Cache nearly 3xxM. (This command is used to immediately clear the Windows File Protection file cache and release the space it occupies. )

8. Delete the dll file under \windows\system32\dllcache (minus 200——300mb). This is a backup dll file. As long as you copy the installation file, you can do it completely.

9.XP will automatically back up the hardware driver, but it is generally unlikely to change the hardware after the hardware driver is installed correctly, so you can also consider deleting this backup. The file is located in the \windows\driver cache\i386 directory and named driver.cab You can delete it directly, usually the file is 74M.

10, delete unused input methods: For many netizens, not all input methods included in the Windows XPt system are suitable for their own use, such as IMJP8_ 1 Japanese input method and IMKR6_ 1 Korean input method. We can delete them if it is not necessary. Input method is located in \windows\ime\ folder, occupying 88M space.

1 1. After upgrading, I found that windows\ has many directories similar to $ ntuninstallq311889 $. Kill them all, 1x-3xM.

12. Besides, putting things in the \windows\help directory is also a kind of harm to me, hehe. . . Kill them all!

13. Turn off system restore: The system restore function takes up a lot of hard disk space for a long time. Therefore, manual setting is needed to reduce the hard disk occupation. Open the System Properties dialog box, select the System Restore option, and select the Turn off System Restore on all drives check box to turn off System Restore. You can also set to restore only the disk or partition where the system is located. Select the partition where the system is located, click the "Configure" button, and cancel the "Turn off system restore of this drive" option in the pop-up dialog box to set the disk space for system restore.

14, the hibernation function will take up a lot of hard disk space. If you use less, you might as well turn off * * *. To turn it off, open the Control Panel, double-click Power Options, select the Hibernation tab in the pop-up Power Options Properties dialog box, and uncheck the Enable Hibernation checkbox.

15, uninstall unused components: XP installs some system components for the operating system by default, and a large part of these components are impossible for you to use. You can uninstall them in Add/Remove Windows Components. However, some components in XP are hidden by default and cannot be found in Add/Remove Windows Components. At this time, you can open the file \windows\inf\sysoc.inf with Notepad, and replace all the "hidden" characters in the file with spaces with the find/replace function. In this way, the hidden properties of all components are removed. After saving, run the Add-Remove program, and you will see many options that you didn't see before. Delete those components you don't need (remember to save them as sysoc.inf instead of the default sysoc.txt), such as Internat messenger service, fax service, Windows messenger, code table, etc. , can release nearly 50MB of space.
