1. Enter: Control Panel-System-Advanced-Environment Variables.

2. Click TEMP-Edit in the user variable to change the long content list to D:TEMP (if necessary, you can change it to another disk, but not the location of the system).

3. ditto, change TMP to D:TEMP. Because these things are the main internal factors that make your system disk expand rapidly, their properties are hidden and some friends can't find them. )

4. In System Variable, change TEMP and TMP to the above values.

5. Right-click My Documents-Properties-Target Folder on the desktop, set the location of the target folder, change it to D:MyDocuments or D: My Documents (you decide which one you like), and then move it at will.

This is very important. In fact, when our computer crashes, there is generally nothing important in the system disk, but all the useful things are in MyDocuments, so move it to a new place and don't worry about anything. Also, quite a few friends will not back up the contents of MyDocuments in DOS mode (because the folder name is very long, it will be more troublesome if it is in Chinese).

6. Right-click InternetExplorer-Properties-General-Temporary Internet Files-Settings-Move Folders-Select D:TemporaryInternetFiles (if not, you can create them first, of course, you can also use D:TEMP or something else, you have the final say)-OK.

7. System-Advanced-Performance-Settings-Advanced-Virtual Memory-Change-Select D or other non-system partitions-Customize the size-Enter the size m-set; Select C or the partition where the system is located-no paging file-Settings-OK to transfer the virtual memory to other hard disks.

Well, the world (system disk) is quiet!

Second, lose weight for XP

1. Delete system file backup.

sfc.exe/purgecache

2. Delete the driver backup

Driver.cab file (73MB) in the windowsdrivercachei386 directory.

3. Cancel the system restore (but remember to keep the system restore of the system disk. Turn it off if you don't want to use it. I'll keep it anyway:)

4. Delete the help file (minus 40 MB)

5. Delete the 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.

6. Install the tool software on the system disk, and install the application software on other hard disks. Special reminder: your FOXMAIL, QQ and other things must not be installed in the system disk. Once the system is finished, you are finished:) (This is also good for reinstalling the system.

7. Delete the input method that is not used under windowsime! (Japanese, Korean, Simplified Chinese Input Method, 84.5MB)

8. If you think you have the ability to handle some emergencies, then install xp with ntfs, which will save the hard disk itself. Don't pretend to be a hero, or you'll cry.

Third, delete the nasty msn and windowsmessenger.

Go to C:windowsinf and open sysoc.inf

Look up msmsgs = msgrocm.dll, okentry, msmsgs.inf, hide, 7, delete hide.

Change to msmsgs = msgrocm.dll, ocentry, msmsgs.inf,, 7, and then save.

Go to Control Panel-Add Delete Program, and you will have the option to delete it.

Fourth, let Dr Watson, an incompetent doctor in China, be laid off.

The doctor looks at the computer and only tells you what the symptoms may be (I don't think he knows what the symptoms are), but he won't tell you what the disease is. The most important thing is that he will never meet you. What's the use of such a doctor? It's better to let him be laid off than to let me be laid off! )

In the "start"->; Enter "drwtsn32" command in "Run", or "Start"->; "program"->; "attachment"->; "system tools"->; "system information"->; "tools"->; "DrWatson", call up Dr.Watson in the system, and only keep the option of "dump 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 find the user.dmp file, which can save tens of MB of space after deletion).

Verb (abbreviation for verb) unloads useless dynamic links.

Deleting a resource manager usually leaves useless dynamic links in memory. In order to eliminate this phenomenon, you can open the registry editor and set the key value: HKEY _ local _ MachisoftWaremicrosoft Windows CurrentVersionXploreralwaySunloadDLL = dword:1,and this function will be turned off. Restart the computer.

6. The software that completely slimmed down WINXP came out! You can uninstall any bundled component. Including IE, OUTLOOK, even MovieMaker, MSN and so on.

Here it is: XPlite

XPliteand2000liteProfessional is a very powerful customization tool for WindowsXP and Windows2000 operating system modules. After the program runs, the system file protection function of Windows will be cancelled first, and then the software configuration in the current operating system will be automatically scanned. Then you are allowed to uninstall modules that cannot be deleted in the operating system at will, such as mobile phone wizard function, task planning function, WindowsSCriptHost module, core font module, help and support center module, voice function module, ODBC database driver module, search assistant module, Windows tutorial, driver cache module, fax module, chat room module, network conference and telephone dialing module. The program * * * contains 9 categories and dozens of setting functions. Through this program, you can completely customize your own unique WindowsXP or 2000, and you can also make the simplest operating system with only core modules through optimization and selection, so that WindowsXP and 2000 can be completely slimmed down.

7. Give the system a "transplant operation"

All the above methods teach you to either clear the relevant files in the system disk or modify the system settings. Perhaps for some people who don't know much about computers, these operations are too complicated and abstruse for him, or they dare not try, for fear that the system will end directly, and finally they will lose their wives and lose their soldiers. In addition, some people's systems are also very important and cannot be deleted or modified casually. Since it can't be modified or deleted, it doesn't mean that the system is bloated and aging day by day. In fact, we can also do a "transplant operation" to the system, remove all seemingly annoying registry information and record files in the system and put them on non-system disks. In addition, all the application software is installed on the non-system disk, so your C disk has only one system, which is completely liberated. The method is also very simple, just download a virtual pocket operating system.

The pocket operating system PrayayaV3 is actually a "green mini windows" and a virtual windows system. It can install a large number of applications on any non-windows system partition including USB flash drives, mobile hard disks, external hard disks, mp3, mp4, cards and other mobile devices. This system is very small, only 10 m in size, and will not take up too much disk space. To realize the "system transplant" I mentioned above, you only need to install the V3 system on the non-system disk of your computer, and then put all the software in this pocket system, especially those who have written many registry files, such as office series software, and chat communication software like MSN and Skype, because their chat records are saved under my documents on the system disk by default, and browsers can also be installed, because their favorites and cookie records are saved. Suppose we install the V3 pocket operating system on the non-system disk D, and then install all the software I mentioned above into this system, so that the registry files will not be written on your system disk, but under the V3system of disk D, including favorites, cookie, history, chat records, VoIP records and emails, which will not be saved on disk C, and will not be disturbed in future updates and upgrades. This is equivalent to sharing the pressure of the system, let it go, completely liberated and concentrate on being your own behind-the-scenes commander. Don't worry that the system will be bloated and aging day by day.

Eight. Use the system cleaning tool

Master of optimization, Super Magic Rabbit is a widely used system optimization cleaning tool. There are many similar tools on the Internet. I believe that many people are skilled in using it, but they all treat the symptoms rather than the root cause, so I won't introduce them in detail here.

In fact, forming the good habit of using and cherishing your own computer is the panacea to keep the system young forever. I hope you can gain something from reading my words above. Don't always reinstall the system, one-click recovery. Maybe you also smashed the mouse and keyboard, and finally the machine crashed and the system crashed.
