It is only recommended for friends with basic computer knowledge!

1. Open "my computer"-"Tools"-"Folder Options"-"View"-tick-"OK" before "show all files and folders"

2. Delete the content in the following folders:
C: \ Documents and Settings \ User Name \ cookies \ All files (keep index files)
C: \ Documents ents and Settings \ User Name \ Local Settings \ temp \ All files (user temporary files)

C: \ windows \ softwaredistribution \ Download all files

3. If you have upgraded the elasticsearch instance, delete the following files:
C: \ windows \ Hidden Files starting with $ u...

4. fragment the disk. Please exit all running programs during the sorting process.

5. after fragment, open "start"-"program"-"attachment"-"system tool"-"System Restore"-"Create a Restore Point" (it is best to pay back the site on the current date ). origin name)

6. open "my computer", right-click the system disk, and choose "properties"> "Disk Cleanup"> "other options". Then, click "clean" in the System Restore column and select "yes" -OK

7. After various software and hardware are installed properly, it is very rare for XP to update files. Delete the system backup file: At the beginning, Run sequence sfc.exe/purgecache near 3xxm. (The purpose of this command is to immediately clear the "Windows File Protection" File Cache and release the occupied space)

8. Delete the DLL file under \ windows \ system32 \ dllcache (minus 200 -- 300 MB). This is a backup DLL file. You can do this if you have copied the installation file.

9. XP will automatically back up the hardware driver. However, after the hardware driver is correctly installed, it is generally unlikely to change the hardware. Therefore, you can also consider deleting this backup, the file is located in the \ windows \ driver cache \ i386 directory and named driver. cab, you can simply delete it. Normally, this file is 74 MB.

10. delete unused input methods: For many netizens, not all input methods provided by Windows xpt are suitable for their own use, such as imjp8_1 Japanese input method and imkr6_1 Korean input method. If not, we can delete it. The input method is located in the \ windows \ IME \ folder, all occupying 88m space.

11. After the upgrade is completed, we found that Windows \ has many more directories like $ ntuninstallq311889 $. All these directories should be killed, 1x-3xm.

12. In addition, keeping the content in the \ windows \ Help directory is a kind of harm to me... All killed!

13. Disable System Restoration: if the system restoration function takes a long time, it will occupy a large amount of hard disk space. Therefore, it is necessary to manually set it to reduce the disk usage. Open the "System Properties" dialog box, select "System Restore", and select the "Disable System Restore on All Drives" check box to disable System Restore. You can also set restoration only for the disk or partition where the system is located. Select the partition where the system is located, click "Configure", cancel the "Disable System Restore for this drive" option in the pop-up dialog box, and set the disk space used for system restoration.

14. The sleep function occupies a lot of hard disk space. If it is used less, close it together. The method is to open "Control Panel" and double-click "power options ", in the displayed "power option properties" dialog box, select the "Sleep" tab and deselect the "enable sleep" check box.

15. Uninstall uncommon components: XP installs some system components for the operating system by default, and a large part of these components are not available to you at all, you can detach Windows Components in "Add/delete Windows Components. However, some of the components XP are hidden by default, and cannot be found in "Add/delete Windows Components". In this case, you can use NotePad to open \ windows \ INF \ sysoc. INF file, replace all the "hide" characters in the file with null with the search/replace function. In this way, the hidden attributes of all components are removed, and the "Add-delete program" program "(such as internat messenger service, fax service, and Windows Messenger) is run after the disk is exited, code table, which can free up to 50 MB of space.

16. Clear temporary system files: the temporary system files are generally stored in two locations: the temp folder in the Windows Installation Directory and the X: \ Documents and Settings \ "username" \ Local Settings \ Temp folder (Y: The partition where the system is located ). Files in both locations can be deleted directly.

17. Clear Temporary Internet Files: regularly delete a large number of Temporary Internet Files generated during Internet access, which saves a lot of hard disk space. Open IE, select "Internet Options" from the "Tools" menu, and select the "General" tab in the pop-up dialog box, in the "temporary files on the Internet" bar, click the "Delete Files" button. In the displayed "Delete Files" dialog box, select the "delete all offline content" check box and click the "OK" button.

18. Clear pre-read files: although the pre-read settings of Windows XP can improve the system speed, after a period of time, the number of files in the pre-read folder will become quite large, as a result, the system search takes longer time. In addition, some applications generate dead-link files, increasing the burden of system search. Therefore, these pre-read files should be deleted regularly. Expected files are stored in the prefetch folder of the Windows XP system folder. All files in this folder can be deleted.

19. NTFS drive, file, or folder compression: If your hard disk uses an NTFS file system, the space is tight. You can also enable the NTFS compression function. Right-click the drive to be compressed-"properties"-"general"-"compress the disk to save disk space", and then click "OK ", select the required option in "confirm property change. This saves about 20% of the hard disk space. When compressing a C disk, it is best to compress it in safe mode, which is better.

20. Disable dr. WATSON: To disable dr. watson can open the Registry Editor, find the "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ AeDebug" branch, double-click the Auto Key under it, and change its "value data" to 0, finally, press F5 to refresh and make the settings take effect. In this way, the operation is canceled. Enter the "drwtsn32" command in "start"-> "run, or "start"-> "program"-> "accessories"-> "System Tools"-> "system information"-> "Tools"-> "Dr Watson ", call dr. Hua from the system. watson, only retain the "dump all thread context" option. Otherwise, the hard disk will read for a long time and occupy a large amount of space in case of a program error. In this case, find the user. dmp file, which can save dozens of MB after deletion.

21. Disable Remote Desktop: remove the "allow remote connection to this computer" check box in "My Computer"> "properties"> "remote" and "allow remote connection to this computer" in "Remote Desktop.

22. Cancel XP zip support: Windows XP opens ZIP file support by default, which occupies certain system resources. You can choose "Start> Run ", in the "run" dialog box, type "regsvr32/u zipfldr. DLL ", press enter to confirm and cancel XP's support for zip decompression, thus saving system resources.

23. Close the Error Report: When an application fails, the window for sending the error report will pop up. In fact, such an error report is of almost no significance to common users, closing it is a wise choice. In the "System Properties" dialog box, select the "advanced" tab and click the "Error Report" button. In the displayed "Error Report" dialog box, select the "Disable Error Report" option, click OK. In addition, you can also disable the error report from the Group Policy: Type "gpedit" in "run. MSC ", run" Group Policy Editor ", expand" Computer Configuration> Manage template> system> Error Report function ", double-click" report error "in the settings column on the right ", in the pop-up "properties" dialog box, select "disabled" to disable "report error.

24. disable unnecessary devices: Windows XP Always tries its best to install and manage drivers for all devices on the computer, which not only slows down the system startup speed, at the same time, it also causes a large amount of system resources to be occupied. In this case, you can disable the uncommon devices such as the PCMCIA card, modem, infrared device, printer port (LPT1), or serial port (COM1) in the Device Manager, double-click the device you want to disable. In the Properties dialog box, select "do not use this device (disable)" on the "General" tab )". The settings take effect after you restart them. enable these devices from the Device Manager when you need them.

25. regularly clear the System Restore Point: Open disk cleanup, select other options-> clear the System Restore Point, and click cleanup.

26. Uninstall unnecessary programs.

27. Other optimizations: A installs the application software on other hard disks (do not install it on the system disk, which is also good for reinstalling the system ); b. Move the "My Documents" folder to another partition. Right-click the "My Documents" icon on the desktop and select "properties"-> "move "; c. Convert all temporary ie folders to other partitions: Open IE browser, select "Tools"-> "Internet Options"-> "general"-> "Settings"-> "Mobile folder"; D. Convert the virtual memory to another hard disk; e put pagefile. the sys file points to one place: Control Panel → system → performance → advanced → virtual memory → change. Note that "setting" takes effect; F on the desktop, right-click my computer and choose Properties> Advanced Performance Settings> advanced virtual memory ", to 330-720. And timed cleaning.

2. the startup of various services is also a major factor that affects the boot speed, and resources are occupied during operation. The following is an optimization of the "service" (suitable for networked home computers ): control Panel-> performance maintenance-> management tools-> services
