First, make the system disk cleaner (you can guarantee the running speed of your computer in a certain program)

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 document-properties-target folder on the desktop, set the location of the target folder, change it to D: my document or D: my document (you decide which one you like), and then move it at will.

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

6. Right-click Internet Explorer-Properties-General-Temporary Internet File-Settings-Move Folder-Select D: Temporary Internet File (if not, you can create it 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:)

Note: I have adjusted the virtual memory, temp and tmp, but I changed it back when installing some software. If you change it, you must remember the original path. )

Second, lose weight for XP (if your hard disk is enough, you don't have to lose weight, because if you want to use one of the functions, there is no way.

1. Delete system file backup.

Sfc.exe/ Puji Cache

2. Delete the driver backup

Driver.cab file (73mb) in the directory of winodwsdriver cachei386.

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 not used under winodwsime! (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 wait to cry.

Third, delete the annoying msn, winodws messenger.

Go to C:winodwsinf 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"->; "Dr. Watson", call out 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).

Unload useless dynamic links.

Fifth, deleting the resource manager often 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 _ machine software Microsoft Windows CurrentVersionXplorer Always Sun LoadDLL = dword:1,and this function will be turned off. Restart the computer.

Sixth, small hard disk users are blessed, and friends with burners can do the gho version of XP.

First of all, when xp is newly installed, it is about 1.5G, and the default hibernation and virtual memory files account for 3 10m. If these two files are closed, it can be reduced to1.2g; Delete C: two compressed packages 80m in c:winodwsdllcab (which only play the role of not playing the system disk at a time) and reduce them to1.1g; I also deleted the 30m Japanese Japanese dictionary (I hate XXXXX), and deleted the unnecessary font in C: Winodwsfon (about 50m) as1g; Delete all the contents of c:winodwssystem32dllcab, which is a copy of dll 320m. You can safely delete it, so it is reduced to 680m m. There are other 250 million forgotten (a little much, Microsoft will be very unhappy when it knows), and interested friends can find it themselves. I heard that the minimum can be reduced to below 400 mm.

Be careful not to delete it wrong. This article is for reference only, please bear the consequences yourself.

Seventh, the software that completely slimmed down WINXP came out! ! You can uninstall any bundled component. Including IE. OUTLOOK, even Movie Maker, MSN and so on.

Here it is: XPlite

There are many download addresses, and here are two:

...MP； searchstr=XPlite

XPlite and 2000lite Professional are very powerful customization tools for Windows XP and Windows 2000 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, Windows script host 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.

It is recommended to make a backup before use! ! ! (it's no use turning)

VIII. The transferee shall be deleted separately.

First, delete all original documents;

Second, delete the original desktop background;

Third, delete the original screensaver (only one is reserved);

Fourth, delete all original games;

Fifth, delete the * * * enjoyment file.

I deleted the above contents in safe mode as an administrator, and some of them still have key values in the registry. You can search and delete them. (Don't delete it wrong)

Nine, delete other useless files, it is recommended to use supercleaner.

X. file compression in X.NTFS partition

Windows XP provides file compression properties for NTFS partition files, which can effectively save disk space.

In the NTFS partition, select the file or folder to be compressed, right-click, select Properties from the shortcut menu, click Advanced on the General tab of the Properties dialog box, and select the "Compress content to save disk space" check box in the "Compression or encryption properties" column of the new dialog box. After confirmation, you will find that the disk space occupied by the file is greatly reduced.

If it's win 7

First open the administrator user and delete other users! ~ ~ This should be no problem! ~~

1. Delete hibernation file.

"Run as administrator, all programs → attachments → command prompt", right-click and select "Run as administrator".

After entering the command prompt, manually enter "powercfg -h off", and Jupiter people will know what this is for. ...

(The file is a hidden system file under the root directory of drive C, and the size of the hidden hiberfil.sys file is exactly the same as its own physical memory. The method of safely deleting the hibernation file is as follows: First, all programs-attachments-administrators open the command prompt, enter (paste directly), powercfg -h off, and press enter, that is, delete directly. The second is to run disk cleanup. If there are hibernation files, check and clear them. )

2. Turn off system protection

Right-click Computer Properties-Advanced Management Settings-System Protection

3. Transfer virtual memory

Right-click Computer Properties-Advanced Management Settings-Advanced-Performance-Settings-Advanced-Change.

4. Transfer "Users' Files"

Double-click the Administrator folder on the desktop, and it is suggested to transfer four system folders.

Desktop, Favorites, My Desktop, My Documents.

Right-click the project property to transfer-location x: \ users \ administrator.

Weight loss strategy (deleting files without deleting functions simplifies the optimization system and simplifies the optimization performance)

Don't waste saliva, just put the valid address in.

1.c: \ Windows \ Web \ Wall * * * (Windows wallpaper) recommended for transfer.

2.c:\ Windows \ System32 \ DriverStore \ File Repository。

Search input ATI *. INF (14.6m) NV *INF (94.9m) (A card users delete N, N card users delete A,-|||)

Search and enter mdm*. Inf (2 1.6M) Delete things that are no longer used.

Search input prn*. Inf (78 1M) prn starts all printer drivers, which I believe most people don't need.

Even if you have a printer, you will buy one with a drive. Delete it!

Note: prnms001.INF/prnoc001.INF/prnms002.inf is not a printer driver, so it is recommended to keep it!

3.c: \ boot (13.3m), Windows startup interfaces in different languages can be deleted except zh-CN.

4. c: \ perflogs \ system \ diagnostics (9.39m) This is the test record file deleted after the system test.

10.C:\ProgramData

Some programs will put some files in when they are installed to see if they need to be deleted.

The installation files exe and msi can be deleted, but some of them are needed when the software is running, and cannot be deleted casually.

1 1.c:\ program file \ Microsoft game

The system comes with its own games, and those that don't play can be deleted. The method of deleting the game is as follows:

Start-Control Panel-Programs-Turn Windows functions on or off, find the game, click the plus sign to expand it, remove the check mark in front of the game to be deleted, and then click OK. At the same time, the functions that can be turned off include tablet optional components /Windows DFS service/printing service /Windows fax and scanning.

Modify the registry

Speed up the startup of Windows 7 system.

1) Run regedit to enter the registry.

2) Open to: HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ prefetch parameters.

3) In the "EnablePrefetcher" primary key on the right, change its default value from 3 to 0.

4) Restart the computer

Modify the registry to speed up the shutdown of Windows 7 system.

1) Run regedit to enter the registry.

2) HKEY _ Current _ User Control \ Panel Desktop ",just set the key value of" AutoEndTasks "to 1.

3) Then change "HungAppTimeout" to "4000 (or below)" (default is 5000), and the key value is also under "HKEY _ Current _ User Control Panel Desktop"; The last step is to find it again.

"HKEY _ local _ machine system current control control", also put WaitToKillServiceTi.

Meout is set to "4000";

Remove menu delay

Removing the delay when the menu pops up can speed up the speed of window7 to some extent. The key value position to be modified is in the

"HKEY _ Current _ User Control Panel Desktop". Modify the "MenuShowDelay" key below it, and set the.

bitscn_com

The default value of 400 is changed to 0. Press F5 to refresh the registry and restart.

Reduce the waiting time before closing applications and processes.

Similar to the waiting time before shutting down services, Windows Vista also has a waiting time before forcibly shutting down applications or processes.

Since the closing time, the Windows system will be forced to stop only after the time limit is exceeded.

Therefore, shortening the default application shutdown or waiting time can also speed up the shutdown of Windows 7.

The setting method is similar to the above, and the following branch is found in the registry: HKEY _ Current _ User \ Control Panel \ Desktop.

Double-click "WaitToKillAppTimeout" in the right panel and change its value from the default value of 20000 (also in milliseconds) to a smaller value of 5000 or 1000.

In this way, if Windows waits for 5 seconds or 1 second after issuing the shutdown instruction and still does not receive the shutdown signal of an application or process, it will pop up a corresponding warning signal and ask the user whether to stop forcibly.

Save hard disk space -Win 7 weight loss strategy

After the release of win7RTM, many friends installed windows7 system, but windows7 system is not as slim as winxp. The newly installed windows7 system takes up more than 10G of hard disk space without installing any software. The author has studied Microsoft's system and found that there are many unnecessary files in the system disk, and deleting them in time has no effect on the use of the system. Next, I will teach you to lose weight on win7.

First, win7 loses weight, deleting the hibernation file hiberfil.sys

I believe many people still don't know what computer hibernation is after using the computer for so long. In fact, computers have two ways to save electricity: hibernation and sleep. The frequently used function is the sleep function. When the computer is not used for a period of time, it enters the sleep function, that is, when the computer enters the low power consumption state after a certain period of time and the working posture is stored in the memory, 1-2 seconds can be restored to the original working state. This function is very practical and most commonly used. However, hibernation is to write the working state, that is, all memory information, to the hard disk. Take 4G memory as an example, that is, write 4G files to the hard disk first, and then turn it off. Boot recovery requires reading 4G files into memory and restoring the original working interface. Reading and writing 4G files takes a lot of time, no less than normal startup, so the hibernation function is not practical now. Heberfield SYS file is used to save the memory state during sleep. It will take up the space equivalent to the memory capacity of drive C (taking 4G memory as an example, this file is 4G), so it can be completely deleted without affecting everyone's use.

Delete method: Run CMD with administrator privileges and play the following command: POWERCFG -H OFF will automatically delete files.

(PS: how to run as an administrator: right-click all programs-> accessories-> command prompt and select "run as an administrator")

Second, the correct setting of win7 virtual memory to lose weight

Memory plays a great role in the computer. All running programs in the computer need memory. If the executed program is large or many, it will lead to memory exhaustion. In order to solve this problem, WINDOWS uses virtual memory technology, that is, a part of the hard disk space is used as memory, which is called virtual memory, and the virtual memory exists on the hard disk in the form of page files. Virtual memory is only a supplement to the lack of physical memory, so don't deify it. The reading and writing performance of virtual memory (that is, the reading and writing speed of hard disk) is only a few tenths of that of physical memory, and high-frequency reading and writing operations are very harmful to hard disk! Hard disk bad track is easy to happen! Don't use it if you can, and use it less if you can! The principle is enough+leave a small margin.

In Win7 system environment, the memory is generally 5 12MB. According to the actual memory usage, the virtual memory can be set to 5 12-768MB (the sum of memory+virtual memory is generally 256MB higher than normal usage). 1GB memory, according to the actual usage of memory, you can set the virtual memory as 128-5 12MB (the sum of memory+virtual memory is generally 256-5 12MB higher than the normal usage). If the memory is more than 2G, you can generally disable virtual memory (if there are software restrictions, you can set a small amount of virtual memory, such as 128MB). Some people who do use a lot of memory, such as playing large 3D games, making large pictures, 3D modeling, etc. , and received a warning that the system memory is insufficient, and virtual memory needs to be increased appropriately.

Generally, you can disable the virtual memory first, restart the computer to enter safe mode (don't run many programs at this time), then defragment it, and reset the virtual memory after completion, so that the page file can be read and written faster without fragmentation. Or use PE/ emergency disk to boot into the system, delete the page file, tidy up the disk, and restart. Take WIN7 as an example, right-click "computer", properties, advanced system settings, performance > settings ..., advanced, virtual memory > change ..., automatically manage cancellation, customize size, set, confirm, exit and restart.

Third, win7 slimming compressed C:\Windows\winsxs folder

This folder is the system installation folder and is not used most of the time. After compression, you can save more than 1GB of disk space. Methods: First, get the read and write permission of the WINSXS folder (by default, the administrator only has the read permission of this folder), then select WINSXS, click the right mouse button, and compress the contents in General-> Advanced ...-> to save disk space. The compression process takes 10-30 minutes, depending on the performance of the hard disk.

Through the above three steps, your Win7 pure system should only account for about 6G.
