2. Delete the contents of the following folder:
All files under c: \ documents and settings \ user name \ cookies \ (keep index files)
C: all files under \ documents and settings \ user name \ local settings \ temp \ (user temporary files).
C:\ Documents and Settings \ user name \ local Settings \ temporary internet files \
All documents under c: \ documents and settings \ user name \ local settings \ history \ (history)
All files under c: \ documents and settings \ user name \ recent \ (shortcuts to recently browsed files)

C:\WINDOWS\ServicePackFiles (backup files after upgrading sp 1 or sp2)
Compressed files under C:\WINDOWS\Driver Cache\i386 (backup files of drivers)
All files under c: \ 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 C:\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. Delete unused input methods: For many netizens, not all the 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 we don't need them. Input method is located in \windows\ime\ folder, occupying 88M space.
10. After upgrading, I found that windows\ has many directories similar to $ ntuninstallq311889 $. Kill them all, 1x-3xM.
1 1. Besides, putting things in the \windows\help directory is also a kind of harm to me, hehe. . . Kill them all!
12. 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. First, 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, then you can set the disk space for system restore.
13, 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.
14. Uninstall unused components: XP will install some system components into the operating system by default, and a large part of these components can't be used at all. 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. You can do this at this time: open the file \ Windows \ INF \ *. INF, and use the find/replace function to replace all the "hidden" characters in the file with spaces. 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 unnecessary components (remember to save them as * * *). Inf instead of the default * *. Txt), such as Internat messenger service, fax service, Windows messenger, code table, etc.
15. Clear the temporary files of the system: the temporary files of the system are generally stored in two locations: a temp folder under the Windows installation directory; The other is the folder C:\Documents and Settings "User Name" \Local Settings\Temp (y: the partition where the system is located). Files in both locations can be deleted directly.
16. Erase temporary Internet files: A large number of temporary Internet files generated when surfing the Internet regularly will save a lot of hard disk space after being deleted. Open IE browser, select Internet Options from the Tools menu, select the General tab in the pop-up dialog box, click the Delete File button in the Temporary Internet Files column, select the Delete All Offline Content check box in the pop-up Delete File dialog box, and click the OK button.
17. Clear the pre-read files: Although the pre-read setting of Windows XP can improve the system speed, after a period of use, the number of files in the pre-read folder will become quite large, resulting in a long system search time. Moreover, some applications will produce dead-chain files, which will increase the search burden of the system. So these pre-read files should be deleted regularly. The expected files are stored in the Prefetch folder of the Windows XP system folder, and all files under this folder can be deleted.
18. Compress NTFS drives, files or folders: If your hard disk uses NTFS file system and space is really tight, you can also consider enabling NTFS compression. Right-click the drive you want to compress-Properties-General-Compress Disk to Save Disk Space, then click OK, and select the required option in Confirm Property Change. This can save about 20% hard disk space. When compressing drive C, it is best to use safe mode for compression, which is more effective.
19. Doctor Guan Hua * * *. Watson: Turn off * * *. Watson, you can open the registry editor, find the branch of "HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ current version \ AEDebug", double-click the Auto key name under it, change its "numerical data" to 0, and finally press. Still in the "start"->; Enter "drwtsn32" command in "Run", or "Start"->; Program-> attachment->; "system tools"->; "system information"->; "tools"->; "Dr. Watson", bring up Dr. Hua. Watson is in the system, and only keeps the option of "dumping all thread contexts", otherwise, once the program goes wrong, the hard disk will be read for a long time, occupying a lot of space. If this has happened before, please look for * * *. Dmp file, after deletion, can save tens of MB of space.
20. Close the Remote Desktop: "My Computer"-> "properties"->; "Remote" and "Allow users to connect to this computer remotely" in "Remote Desktop" are ticked.
2 1. Cancel XP's support for ZIP: Windows XP turns on support for zip files by default, which takes up some system resources. You can choose "Start → Run" and type "regsvr32 /u ***". Dll ",and press Enter to confirm that XP can cancel the support for ZIP decompression, thus saving system resources.
22. Turn off the error report: When the application fails, a window will pop up to send the error report. In fact, such an error report is almost meaningless to ordinary users, so it is a wise choice to close it. In the System Properties dialog box, select the Advanced tab, click the Error Reporting button, select the Disable Error Reporting option in the Error Reporting dialog box that pops up, and finally click OK. In addition, we can turn off error reporting from Group Policy: type "* * *". From Run, run the Group Policy Editor, expand Computer Configuration → Management Template → System → Error Reporting Function, double-click Error Reporting in the setting bar on the right, and select the Disable radio box as Error Reporting in the pop-up Properties dialog box.
23. Turn off unused devices: Windows XP always tries to install drivers for all devices of the computer and manage them as much as possible, which will not only slow down the system startup, but also cause a lot of system resources to be occupied. In view of this situation, in the device manager, you can disable uncommon devices, such as PCMCIA cards, modems, infrared devices, printer ports (LPT 1) or serial ports (COM 1). Double-click the device you want to disable and select Do not use this device (disable) in the General tab of its properties dialog box. Settings will take effect when you restart, and then enable these devices from Device Manager when you need to use them.
24. Regularly clean the system restore point: turn on disk cleaning, select other options-> Clean the system restore point, and click Clean.
25, uninstall unnecessary programs, I don't need to say this.
26, other optimization:
A. Install the application software on other hard disks (don't install it under the system disk, which is also good for reinstalling the system);
B. Transfer all My Documents folders to other partitions: right-click the My Documents icon on the desktop and select Properties-> "moving";
Transfer all IE temporary folders to other partitions: open IE browser and select "Tools"->; "internet options"->; "general"->; "settings"->; "Move folder";
Transfer the virtual memory to another hard disk;
E point all * * *. The sys file goes to one place: Control Panel → System → Performance → Advanced → Virtual Memory → Change, and pay attention to the key points for the "Settings" to take effect;
Right-click the "My Computer" icon on the desktop and select "Properties"-> "advanced-performance settings"->; Advanced-Virtual Memory, set to 330-720. And clean it regularly.
Virtual memory setting skills
Under normal circumstances, windows XP uses the remaining space of drive C as virtual memory by default. Therefore, the larger the remaining space of drive C, the better it will run on the system. Virtual memory changes dynamically with your use, so disk fragmentation is easy to occur on disk C, which affects the running speed of the system. Therefore, it is best to set the virtual memory in other partitions, such as drive D. Check the virtual memory settings as follows:
Right-click My Computer, left-click Properties, click the Advanced tab, click the Settings button in Performance, then select the Advanced tab, and click the Change button below to open the virtual memory settings window. Generally, the default virtual memory is a range of values from small to large, that is, the range of virtual memory changes. The specific value depends on the size of your physical memory, which is generally 0.5 to 2 times that of 65438+ physical memory. If the memory is 256M, you should set 256* 1.5=384M, or just 5 12M. The setting method is as follows:
Assuming that the memory is 256M and the virtual memory is placed on drive D, clear the default first, keep drive C selected, select "No paging file (n)" and press the "Set" button, and the virtual memory next to drive C will disappear. Then select drive D, select User-defined Size, and add 50 in the Initial Size and Maximum Value boxes below. You will see the words "5 12-5 12" next to disk D, indicating that it is set up, and then confirm it all the way. Finally, the system must be restarted to complete the setup.
Note: there can only be one virtual memory, only on one disk!
***.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 ***.cab. Just delete it directly. Usually this file is 74M.
28. 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 the IMJP8_ 1 Japanese input method and the IMKR6_ 1 Korean input method. We can delete them if we don't need them. Input method is located in \windows\ime\ folder, occupying 88M space.
29. delete the dll file under \windows\system32\dllcache (minus 200——300mb), which is a spare dll file. As long as you copy the installation file, you can do this completely.
30. Uninstall unused components: XP installs some system components for the operating system by default, and a large part of these components are unavailable to you. 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. You can do this at this time: open the file \ Windows \ INF \ *. INF, and use the find/replace function to replace all the "hidden" characters in the file with spaces.
