When you turn off your phone, sometimes an annoying dialog box will pop up to remind you that a program is still running, whether to end the task or not. In fact, with a little modification, you can let Windows automatically end these programs that are still running. Open HKEY _ Current _ User \ Control Panel \ Desktop directory in the registry, and change the key value of AugoEndTasks to 1.

2。 Internet time synchronization

If you use time synchronization ~ then your computer will check with the online time server at regular intervals, wasting some memory. It is recommended to turn it off, because the time deviation will be almost good when your computer starts to adjust the time. Start of closing mode → control panel → date and time language and regional options → date and time → Internet time closing synchronization ~

3。 Turn off the fast user switching function.

A striking function of WIN XP is called "fast switching", which allows many users to use computers at the same time, but this function also consumes a certain amount of memory. If your memory is installed with 64M WIN XP, this function will be automatically disabled ~ It will be a bit too much for users of 128M, so it is suggested to close ~ Method Control Panel → User Account → Change the login or logout mode of users and remove the use of fast user switching ~

4。 Speed up menu display.

Open the Registry Editor, find HKEY _ Current _ User \ Control Panel \ Desktop, and change the MenuShowDelay item (400) below it to 0, and your menu will be unexpectedly fast.

5。 Delete system backup

XP system will automatically record some key information of hardware configuration and registry. Actually, we don't need this at all. When the system crashes, we can completely restore the system by backing up a large number of GHOST in advance. Delete system file backup, start → run → enter sfc.exe/purgecache and press enter (save 300MB+ ~).

Ditto is the driver of XP system backup. Delete the Driver.cab file (73mb) in the windows\drivercache\i386 directory.

We can usually delete *. Dll files automatically backed up by the system. He can delete the file (minus 200-300mb) under \WINDOWS\system32\dllcache (this is a spare DLL file, so long as the installation file is copied, it is completely possible. In this case, you have nothing to say

6。 Delete WINDOWS XP help files

XP system comes with very detailed help files to help you better understand various new functions and configurations of XP system, so that you can do better (if you don't know WINDOWS yet, please don't delete the help files).

7。 System variable setting

Transfer my documents and IE temporary folder to another disk (partition). 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.

Transfer virtual memory to another disk. (Just put these things and the temporarily downloaded files in a small partition, which is also convenient for sorting out the hard disk.)

Install the application software on other disks (this is also good for reinstalling the system and can save a lot of things).

8。 Delete redundant input methods and redundant language types.

Delete the input method that is not used under \windows\ime! (Japanese, Korean, traditional Chinese input method, 84.5MB) (which is which? Find out for yourself! Sometimes you have to use your brain. Do some exercise! )

Delete unnecessary input methods

Right-click the input method icon in the lower right corner of the desktop to delete unnecessary input methods. Everyone knows this, but look at the empty hard disk.

Time has not decreased. Why? It turns out that Windows didn't delete the files related to the input method, but we had to delete them.

Delete it manually by yourself. The following is a list of files related to the input method included with Windows:

Full spell: Winpy.ime, Winpy.mb, Winpy.hlp, Winpy.cnt

Double spelling: Winsp.ime, Winsp.mb, Winsp.hlp, Winsp.cnt

Micro spelling: Pintllime.dll, Pintlgab.imd, Pintlgai.imd, Pintllgb. IMD，Pintlgd.imd，Pintlgie.imd，Pintlgnt.cnt，Pintlgnt.hlp，Pintlgnt.i96，Pintlgnt.ime，Pintlgrb.imd，Pintlgri.imd，Pintlgs.imd，Pintlgsi.imd，Pintlgsx.imd，Pintlgu.imd，Pintlguc.imd， Pintlphr.exe .

Intelligent ABC:Winabc.cwd, Abcsda.dll, Abcwin.exe, Winabc.ime, Winabc.ovl, tmmr.rem, user.rem, Winabc.hlp, Winabc.cnt

Zheng code: Winzm.ime, Winzm.mb, Winzm.hlp, Winzm.cnt

Internal code input methods: Wingb.mb, Wingb.hlp, Wingb.cnt

Table codes: Winbx.mb, Winbx.ime, Winbx.hlp, Winbx.cnt

9。 Turn off redundant system reporting

If your system crashes and you find your hard disk loud, it's because windowsXP is writing a dump file, which is useless to us. Can you still send this error to Microsoft? ~ it's completely unnecessary. What if I turn it off? ~ Click on my computer → Properties → Advanced → Startup and fault recovery → Settings → If the system fails, only choose automatic restart, not debugging information.

10。 Delete * * * Enjoy the document:

By default, when I open my computer in Windows XP, I will see some folders above the hard disk icon. These are "* * * Shared Folders", and there are folders for everyone to enjoy files. These folders are particularly annoying and unnecessary. We can make these folders disappear in my computer: open the registry editor and delete HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Explorer \ My Computer \ Namespace \ {59031a47-3f72-4a7-89c5-5595fe6b30ee} under the Delegate folder, these annoying folders will be deleted the next time I open my computer.

1 1。 Shorten the waiting time of program response

Open registry editor

Find HKEY _ local _ machine \ system \ current control set \ control, and set WaitToKillServiceTimeout to: 1000 or less (original setting: 20000).

Find the HKEY _ Current _ User \ Control Panel \ Desktop key, and change the WaitToKillAppTimeout in the right window to 1000 (original setting: 20000), that is, just wait for 1 second when closing the program. Change the HungAppTimeout value to: 200 (original setting value: 5000), which means waiting for 0.5 seconds when the program makes an error.

12。 System acceleration

Manually identify the secondary cache of cpu to improve the performance of cpu;

Found "[HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ second-level data cache]"; Modify its decimal system:

AMD duron: 64 (kb);

Celerona/Celerona 2:128;

PII/PIII E(EB)/P4/AMD K6-3/AMD Thunderbird/Cyrix III: 256;

AMD K6-2/PII/PIII Katmai /AMD Athlon: 512;

PII Xeon /PIII Xeon:1024;

Modify the disk cache to speed up xp. Disk cache plays a vital role in xp operation, but the default I/O page file is conservative.

Go to [HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ iopagelocklimit];

Modify its hexadecimal value according to your memory:

64M: 1000；

128m:4000；

256m: 10000；

More than 5 12M: 40000.

Pre-reading setting improves the speed, and xp adopts the new technology of pre-reading setting to improve the system speed.

Go to [HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ prefetch parameters \ enable prefetcher];

Set the value to 0, 1, 2,3. 0- Disable, 1- Read ahead the application, 2- Start reading ahead, 3- Read ahead both ("3", recommended). Of course, if you want to be quick, you can choose 0.

13。 Let the system automatically shut down the program that stops responding.

Open the HKEY _ Current _ User \ Control Panel \ Desktop key in the registry and set the AutoEndTasks value to 1. (Original setting value: 0)

MsConfig. Most friends should be familiar with MsConfig, which is a built-in Windows installation tool.

Click the Start menu, select Run, and then type msconfig in the input box and press enter. What we need to do is tamper with the label. Click it. This tab shows all programs that were running when Windows started. There are no life-and-death programs for Windows, so you can delete unnecessary programs at will. After removing some checkmarks, Windows will start faster and there will be more idle system resources.

14。 System stability optimization setting.

Turn off the debugger, Dr. Watson; ;

Dr.Watson is a self-contained system maintenance tool, which will be displayed when the program fails to load or crashes. Run drwtsn32 to delete everything except "Dump all thread contexts". Otherwise, once a program goes wrong, the hard disk will ring for a long time and take up a lot of space. If you have encountered this situation before, please find the user.dmp file to delete, which may save tens of MB of space.

15。 System repair and maintenance

Turn off System Restore. DOS operating system has not been attached to WIN since WIN2000, but it is a system restoration method. Of course, this method is very simple and suitable for users who don't know much about DOS, but it does waste a lot of disk space and memory space. The way to turn off system restore is to right-click "My Computer" on the desktop and select "Properties" to find "System Restore". If you can use DOS to repair the system, you can save a lot of space.

Turn off hibernation support: Because hibernation takes up a lot of hard disk space, it is best to turn it off. Console->; Power options-> Hibernate (don't tick) Turning off hibernation can save some hard disk space and memory.

16。 Optimized program operation

Programs run according to their own priority order, all programs occupy processor resources, and processors have priority order. In a general computer, there are 365,438+0 priorities, and the kernel of the system occupies the highest level, thus ensuring the stability of the system, while ordinary applications are generally at a lower level. There are also priorities in general applications. All are equal in front of the processor, but there are still some subtle differences. The foreground program (currently in use) has higher priority than the background program. You can adjust the priority of the application by yourself, open the task manager, click the "Process" tab, select a process of the application, right-click to pop up the shortcut menu, and select "Set Priority". There are six levels here: real time, high, high and standard, standard, sub-standard and low. You can force your program to be scheduled to a higher or lower level (naturally freeing up resources for other programs). If you don't know the specific process of an application, you can do this: click the "Application" tab, right-click a task, and select "Go to Process" to go to the process of the application, so that you can find the process of the application.

17。 Reject grouping similar taskbar

Although the setting of "similar taskbar button grouping" in Windows XP can make your taskbar open fewer windows and keep it clean, it is very inconvenient for some jobs that need to open multiple similar windows. If you often use QQ and other communication software to chat with people online, if there are more than two friends chatting with you at the same time, you will immediately feel the inconvenience caused by XP default settings. D D Every time you want to switch conversation objects, you should first click on the group, and then select the friends you want to talk to in the pop-up menu. Each friend displays the same icon in the group. When there are a lot of conversation objects, you may want to click one by one to see who replied just now and wait. Obviously, it is better to open several windows and click on each small window in the taskbar to start chatting. Change method: Click Start → Control Panel → Appearance and Theme → Taskbar and Start Menu, and remove the check in front of the option "Grouping similar taskbar buttons" in the pop-up window.

18。 Modify the login background mode of Windows XP

You may get tired of the monotonous login mode for a long time. We can change it to your favorite pattern through the registration form. The steps are as follows: Open the Registry Editor and find the subbranch of HKEY _ user. Default \ Control Panel \ Desktop, double-click wallpaper, enter the path of your selected picture, for example: C: \ Documents and Settings \ My Documents \ MyPIC.bmp, click OK, then find Tilewallpaper, double-click it, enter the key value "1", and restart the system to see the effect.

19。 Let Win XP support large hard disks above 137 GB.

If you want to use a large hard disk above 137 GB, you must use 48-bit LBA mode. Firstly, your motherboard BIOS must support 48-bit LBA, and secondly, the home edition and professional edition of Win XP must install SP 1 patch. Then open the registry and find the "EnableBigLba" option in the following path "HKEY _ Local _ Machine System Current Control Set Service atapi Parameter" and change its value from "0" to "1". If the item does not exist, you can build your own DWORD Value item, set it in the same way, and then restart it.

20。 Solve the task bar fake death

"control panel"->; "regional and language options"->; "language"->; For more information, please select the preferred language bar in the pop-up setting window, turn off the display of the language bar on the desktop, and check the third check box "Show other language bar icons in the notification area". If handwriting recognition and speech recognition are not needed, you can also check the last item "Turn off advanced text service".

2 1。 Keep the desktop settings unchanged every time you start.

We can protect our desktop settings by modifying the registry. No matter what changes are made, the desktop will be restored after restarting. The steps are as follows: open the registry editor, find the sub-branch of HKEY _ current _ user \ software \ Microsoft \ Windows \ current version \ policy \ resource manager, find NoSaveSettings under it, and change its key value to "0", or delete it directly, and restart the system to make the settings take effect.

22。 Change Windows XP serial number

After installing Windows XP, for some reason, you may want to change the serial number on the installed Windows XP. What should I do? Use the activation wizard to meet your requirements.

Note: Before starting, it is recommended that you make a system backup before modifying. GHOST is recommended to avoid unnecessary troubles caused by misoperation.

Click Start → Run, enter regedit, open the Registry Editor, navigate to HKEY _ Local _ Machine \ Software \ Microsoft \ Windows NT \ Current Version \ WPEvents, right-click the OOBETimer on the right, then select Modify, at least one byte, and confirm to save.

Click Start → Run, enter% systemroot% \ system32 \ oobe \ msoobe.exe/a, Select to activate by phone, then click Next, click Modify Serial Number, enter a new serial number, and then select Update. If you return to the previous screen, choose to activate and restart later and repeat the previous steps until the modification is successful. Click OK to install SP 1.

If you can't restart after installing SP 1, press F8 when starting, select Use Last Known Good Configuration, and then repeat the above process. This method is applicable to Windows XP Professional.

23。 Disable script error reporting

When IE encounters a script error in a page, it will report an error. Unless you are debugging your own program, even if you know the details of the error, there is no way to correct it. So for most users, reporting script errors is an ugly function. The methods to prevent the browser from reporting script errors are as follows:

Select Internet Options from IE's Tools menu. Select the Advanced tab. Scroll down the list and find the browse area. Locate "Scriptless Debugging" and select the previous check box.

24。 Solution of Forgetting Login Password

Windows XP is very strict in auditing users' security. As we all know, the mechanism of Security Account Manager (SAM) is used for the security management of user accounts in Windows XP. The security account manager manages accounts through security identities, which are created at the same time as the accounts are created. Once the account is deleted, the security logo is also deleted. The security identification is unique, even if it is the same user name, the security identification created each time is completely different. Therefore, once the account is deleted, its security identity no longer exists, that is, if the account is rebuilt with the same user name, it will be given a different security identity and will not retain its original rights.

The specific performance of the security account manager is the% systemroot% \ system32 \ config \ Sam file. SAM file is the user account database of Windows NT/2000/XP, and all users' login names, passwords and other related information will be saved in this file. Knowing this, our solution came into being: before the system starts, insert the startup disk, enter C:\WINNT\System3\Config\, rename the SAM file with ren command, or delete the SAM file with del command and restart the computer. After renaming or deleting the SAM file, I tried to log in with Administrator, and the password was empty, which succeeded.

25。 Compressed folder

This is a very good optimization. Windows XP has built-in. ZIP file, so we can browse the zip file as a folder. But the system needs to use some resources to realize this function, so disabling this function can improve the system performance. The implementation method is simple, just cancel the registration of zipfldr.dll, click Start-Run, and enter: regsvr32/u zipfldr.dll. Then get into the car.

26。 Turn off unnecessary services.

Click Start → Settings → Control Panel. Double-click Administrative Tools → Services, and you will see a list of services, some of which have been started and some of which have not. Right-click the service you want to configure, and then click Properties. Select "Automatic", "Manual" or "Disabled" on the General tab, where "Automatic" means that WindowsXP automatically starts the service every time the system starts; "Manual" means that WindowsXP will not automatically start the service, but manually start the service when you need it; Disabled means that starting the service is not allowed. In the actual configuration, you can turn off the service by selecting Manual or Disable. Manual function is recommended, so that some temporary services can be started at any time. Some services are necessary for WindowsXP and cannot be shut down, otherwise the system will crash. As for the functions of various services, we can view them by double-clicking the service or hovering the mouse over the service name. The description of the specific service is easy to understand, and you can choose whether you want it or not. The modification method is: select the disabled service, right-click Properties > Stop, and set the Start Type to Manual or Disabled.

27。 Automatic landing

Click Start → Run, enter "rundll32netplwiz.dll, users rundll" (without quotation marks), then cancel "Users must enter user name and password to use this computer" in the user account, click OK, and then enter the user name and password you want to log in in the pop-up dialog box.

28。 Quick Shutdown or Restart Shortcut (Timeable)

Click the right mouse button on the desktop, select a new shortcut, and enter the location in the pop-up wizard: C: Windows System32Shutdown. Exe -s -t 10 (where -s can be changed to -r, which means restart, and -t 10 means delay 10 second, which can be changed according to your own needs). After creating this shortcut, specify an icon for it according to the above method. This fast shutdown or restart technology will display a beautiful dialog box to prompt shutdown (restart). You can add "-c" after it, I want to shut down! "",so this sentence will be displayed in the dialog box. Of course, you can write the text at will, but be careful not to exceed 127 characters.

29。 It is also recommended to use GHOST to back up the system ~

The suggestion is that XPlite slim down WINDOWSXP and delete those WINDOWS group files that you think are useless and can't be deleted ~

Originally, WINDOWSXP needed about 2gb, but if you optimize it by the optimization method we introduced, you will find that Wow WINDOWS only saves about 1.2G ~ haha ~
