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

2. If the system is frequently patched and upgraded in windoes updade, the following files will be deleted: C:-windows- hidden files starting with "$u ..." (when Windows patches these files, they can be safely deleted). Note: Other disks may also have such files, so do the same.

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

4. Delete unused input methods: Not all input methods that come with Windows XP systems are suitable for your own use, such as IMJP8 _/KOOC-0/Japanese input method and IMKR6 _/KOOC-0/Korean input method. If they are not used, we can delete them. The input method is located in the folder C c-windows-ime-,occupying 88M space.

5. Turn off system restore: If the system restore function is used for a long time, it will take up a lot of hard disk space. 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.

6. 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 Power Options, select the Hibernation tab in the pop-up Power Options Properties dialog box, and uncheck the Enable Hibernation checkbox.

7. Uninstall unnecessary programs and try to put some unnecessary programs on other disks, such as D E, etc.

8. Transfer the virtual memory to another hard disk. Methods: Control Panel → System → Performance → Advanced → Virtual Memory → Change. Please note that the Settings will take effect; Or right-click "My Computer" on the desktop and select "Properties"->; "advanced-performance settings"-> "advanced-virtual memory", adjusted to about 1.5 times of actual memory. And clean it regularly. (For example, if your memory is 1G, you can set it to1024 *1.5 =15360m).

10, 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.

1 1. Close Dr.Watson: To close Dr.Watson, open the Registry Editor, find the branch of "HKEY _ Local _ Machine-Software-Microsoft -Windows NT- Current Version -AEDEBUG", double-click the name of the Auto key under it, and change its "Numerical Data" to 0. Still in the "start"->; Enter "drwtsn32" command in "Run", or "Start"->; "program"->; "attachment"->; "system tools"->; "system information"->; "tools"->; "Dr. Watson", call out Dr. Watson in the system, and only keep the option of "Dump all thread contexts", otherwise the hard disk will be read for a long time and occupy a lot of space once the program goes wrong.

12, close the remote desktop: "My Computer"->; "properties"->; "Remote" and "Allow users to connect to this computer remotely" in "Remote Desktop" are ticked.

13. Cancel XP's support for ZIP files: Windows XP turns on support for zip files by default, which takes up some system resources. You can choose Start, type "regsvr32/u ZIPfldr.dll" in the Run dialog box, and press enter to confirm that XP can cancel the support for zip decompression, thus saving system resources.

14. Turn off error reporting: When the application fails, a window will pop up to send an error report. In fact, this error report is almost meaningless to ordinary users. Close is a wise choice: click Start, type "gpedit.msc" in Run, run the Group Policy Editor, and expand "Computer Configuration → Management Template → System → Error".

15, XP will automatically back up the hardware driver, but it is 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 C-Windows-Driver Cache-I386 directory, named driver.cab. You can just delete it directly. Generally, these files are tens of meters.

16. 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 startup speed of the system, 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.

17, 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-infsysoc.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.

The following cleaning methods can be cleaned with the help of cleaning software such as "Optimization Master", "Super Rabbit" and "360 Security Guard" (manual handling is too troublesome).

1. 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 C:- Documents and Settings "User Name"-Local Settings-Temp folder. Files in both locations can be deleted directly.

2. Clear temporary files on the Internet: Deleting a large number of temporary files on the Internet during regular surfing will save a lot of hard disk space. 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.

3. 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 longer 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.
