2. Delete the contents of the following folder:
All files under xDocuments and Settings user name Cookies (keep index files)
X documents and all files (user Temporary files) under setting the user name and local setting temp.
X documents and all files (page files) under the setting user name set temporary internet files locally.

3. If the system has been upgraded by windoes updade, please delete the following files:
Hidden files starting with $u ... under xwindows
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 clears the cache for 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 windowssystem32dllcache (minus 200——300mb), which is a spare 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 windowsdriver cachei386 directory and named driver.cab You can delete it directly. Usually this 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. The input method is located in the windowsime folder, occupying 88M space.
After upgrading 1 1., many directories similar to $ ntuninstallq311889 $ were found in windows. Kill them all, 1x-3xM.
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 then 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 in the pop-up dialog box, cancel turning off the system restore option of this drive, and then you can set the disk space for system restore.
13. Hibernation will take up a lot of hard disk space. If you use less, you might as well turn off * *. The closing method is: open the control panel, double-click the power option, select the hibernation tab in the pop-up power option properties dialog box, and uncheck the hibernation check box.
14, 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 Windows components when they are added or removed. However, some components in XP are hidden by default and cannot be found in adding or deleting Windows components. At this time, you can do this: open the file windowsinfsysoc.inf with notepad, and replace all hidden characters in the file with spaces with the find and replace function. In this way, the hidden properties of all components are deleted. 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. , you can free up nearly 50MB of space.
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 xDocuments and Settings user name local SettingsTemp folder (Y is 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 option in the Tools menu, select the General tab in the pop-up dialog box, click the Delete File button in the Internet Temporary File bar, select the Delete All Offline Content checkbox in the pop-up dialog box, and click OK.
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. Close Dr.Watson: To close Dr.Watson, you can open the Registry Editor, find the branch of HKEY _ local _ MachineSoftwareMicrosoft Windows ntCurrentVersionaeDebug, double-click the name of the Auto key value under it, change its numerical data to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. At start-run, or start-program-accessories-system tools-system information-tools-Dr. Watson enters drwtsn32 command, and Dr. Watson is called out in the system. Only the option of dumping all thread contexts is reserved, otherwise, once the program goes wrong, the hard disk will be read for a long time and occupy a lot of space. If this has happened before, please look for the user.dmp file, which can save tens of MB of space after deletion.
19. Close the remote desktop: My Computer-Properties-Remote, and "Allow users to connect to this computer remotely" in the remote desktop is ticked.
20. Turn off the error report: When there is an error in the application, 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. Select the advanced tab in the system properties dialog box, click the error report button, select the option to disable the error report form in the pop-up error report dialog box, and finally click OK. In addition, we can turn off error reporting from the group policy: type gpedit.msc from running, run the group policy editor, expand the functions of computer configuration → management template → system → error reporting, double-click error reporting in the setting bar on the right, and select the disable radio box in the pop-up properties dialog box to disable error reporting.
2 1. Turn off unused devices: Windows XP always tries to install drivers for all devices of the computer and manage them, which will not only slow down the system startup, but also cause a lot of system resources. In view of this situation, you can disable devices that are not commonly used, such as PCMCIA cards, modems, infrared devices, printer ports (LPT 1) or serial ports (COM 1), by double-clicking the device to be disabled and selecting 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.
22. Regularly clean the system restore point: Turn on disk cleaning, select other options-Clean the system restore point, and click Clean.
23, uninstall unnecessary programs
24, 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 document folders to other partitions: right-click my document icon on the desktop and select Properties-Move;
C transfer all IE temporary folders to other partitions: open IE browser and select Tools-Internet Options-General-Settings-Move Folders;
