1. Delete the system file backup sfc.exe/Purge cache (rarely used by ordinary users).
2 delete the Driver.cab file (73mb) in the windows\driver cache\i386 directory.
3. Cancel the system restore (generally speaking, the system restore function is good, and it is recommended to use everything except the one installed by xp. If there is not enough hard disk space one day, you can delete some earlier restore points through the system cleaning process)
4. Delete the help file (minus more than 40 mb) (the file size of the Chinese localization package is 92 megabytes, so comrades who just started using xp had better not delete it).
5. Delete the files 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. In this case, you have nothing to say
6. Transfer my documents and IE's temporary folder to other disks (partitions). At the same time, it is good for the speed of the system and the hard disk. If you use a dual system, it is best to put the IE temporary files of the two systems in the same folder, which will speed up and save space. )
7. Transfer the virtual memory to another disk. It's best to put these things and the files downloaded temporarily in a small partition, which is also convenient for sorting out the hard disk. )
8. Install the application software on other disks (this is also good for reinstalling the system and can save a lot of things).
9. If you install xp with ntfs, the site itself will be saved.
10. Uninstall uncommon components: use Notepad to modify %windows%\inf\sysoc.inf, use the find/replace function, enter, hide in the find box, and replace all with blanks. In this way, all the "hiding" is removed. After saving the disk, run "Add-Remove Program", and you will see many more options in "Add/Remove Windows Components". Delete games, code watches and other unused things.
Then introduce how to cclean.
I. Junk files generated by system operation
In most cases, the garbage generated by system operation is to improve the usability of the system. In some cases, these designs of Windows do bring a lot of convenience to users, even though they are really useless junk files. These include:
Junk in 1, "Start"-"Recently Visited Documents": This is because Windows is smart enough to put a link to the files recently used by the system here. I believe it will be of great help to me.
Clear method: Right-click Start, select the (Properties) command, then click Customize, select the Advanced tab, click the Clear List button, and clear the "List Recently Opened Documents" check box. Empty the My Recent Documents folder. This operation will not delete related documents from your computer.
2. Temporary files generated when installing programs and editing files: Many installation programs are self-extracting, and then the installation starts when the C disk is released. In addition, the design problem of Windows Installer is the root cause of many junk files. In the process of software running, some temporary exchange files are usually generated. Some software comes with redundant font libraries and help files, and some are hidden in temporary folders such as "c:\windows\temp" and corresponding places in user folders, even Windows\system32. Even if the software is uninstalled, it will leave some residue. Dll dynamic link library file or leave your own figure in the registry.
Cleaning method: Because there are many locations of files, in addition to cleaning specific known junk folders, we click the Start menu, select "Files or Folders" under the "Search" command, and enter the file suffix to be deleted. Chk as a temporary file with a suffix of *. tmp，*。 _mp and temporary backup with suffix *. bak，*。 Old, *. Syd, etc After searching, delete all these files.
For convenience, we can create a batch file, which is very convenient to remove all garbage after execution:
Open Notepad and enter the following:
@ Turn off echo
rmdir /s /q %temp%
del tree–y C:\ windows \ temp \ *。 *
deltree -y C:\RECYCLED\**
Deltree-y c: \ documents and settings \ (current user name) \Local Settings\Temp
DEL /F /Q /S C:\*。 Terminal Monitor Program (abbreviation of terminal monitor program)
DEL /F /Q /S C:\*。 _mp
DEL /F /Q /S C:\*。 Dizziness
DEL /F /Q /S C:\*。 Sum of the Year's Digits.
DEL /F /Q /S C:\*。 old
DEL /F /Q /S C:\*。 chk
DEL /F /Q /S C:\*。 bak
Change the suffix of the text file to ". Bat ". In the future, as long as you double-click to run this bat batch file, it will clean up the garbage on drive C, which can be added to the group policy to automatically shut it down. Enter gpedit.msc in Start-Run to open the group policy, enter Computer Configuration -Windows Settings-Script (startup/shutdown), double-click shutdown in the right pane, then click Add, and enter the path of this bat file in the script name. In this way, every time the computer is turned off, the system will automatically clean up the junk files (the shutdown time may be a little longer).
3. Temporary files, Cookies and history of 3.IE browser: Temporary files are helpful to speed up web browsing, and history is convenient for users to find previously visited web pages. Cookies are essential for website logo users. Although these are not essential for the operation of IE, they are really convenient for users to surf the Internet.
Cleaning method: There are corresponding deletion methods in IE's menu "Tools-Internet Options-General". We'd better limit the size of temporary files according to our own network speed and disk conditions. For Cookies, it is recommended to keep them if they are not public computers.
2. Legacy operation after software uninstallation:
1, uninstall some software normally, and sometimes right-click will leave some unnecessary items, such as some antivirus and shortcuts of drawing software.
Cleaning method: these legacy items are generally stored in the registry [HKEY _ class _ root \ * \ Shellex \ context menu handler], [HKEY _ class _ root \ directory \ shell], [HKEY _ class _ root \ directory \ Shellex \ Context Menu Handlers] and [HKEY _ class _ root]. Find software-related key values in the registry, find and delete them.
2. Right-click-Create a new submenu We often only use new folders, new word documents, etc. Many softwares will add content to it.
Cleaning method: delete the "ShellNew" item under [HKEY _ Class _ Root]. * *] (".* *" is the file extension of the item to be deleted), and then exit Registry Editor and restart the computer.
3. Right-click a file, and there may be many unnecessary items in the "Open Method" submenu.
Cleaning method: the corresponding location of the registry is:
[HKEY _ current _ user \ software \ Microsoft \ Windows \ current version \ resource manager \ fileexts] and [HKEY _ class _ root \ system file association], just delete unnecessary key values or items in the "OpenWithList" subitem.
Three. Advanced skills
1, menu startup item: Many softwares will add startup items to the registry, which is the chief culprit for the slow running of many novice computers.
Cleaning method: In addition to the "Program-Start" item in the start menu, run (and RunOnce) in [HKEY _ local _ machine \ software \ Microsoft \ Windows \ current version] and [HKEY _ current _ user \ software \ Microsoft \ Windows \ current version \ run (. We can also run "msconfig" to clear the startup items.
2. Useless shortcuts are little-known rubbish in Windows. We changed the folder where a certain software is located, but its shortcut still points to the original location, or the software has been uninstalled or the file has been deleted, but there are still corresponding shortcuts in the corresponding shortcut operation, and there are records of historical shortcuts of software such as media playback and word processing. Over time, it will drag down the system operation.
Finally, it is suggested that:
Install the latest version of Super Rabbit, and system optimization can easily remove garbage.
Ps: Transfer all temp to other disks: My Computer-> Properties-> Advanced-> Environment Variables.
You should change the user variable temp tmp to another disk, such as d: \ temp. The addresses of the two variables should be consistent, and the address of the batch file corresponding to deleting garbage mentioned above should also be changed.
