1. Delete attachments imposed by Windows:

1) Use Notepad to modify \winnt\inf\sysoc.inf, use the find/replace function, enter, hide (English comma followed by hide) in the find box, and set the "Replace with" box to be empty. And choose to replace all, so that all hiding is removed,

2) Save and exit,

3) Run Add and Remove again, and you will see several options in Add and Remove Windows components; This can delete many useless attachments.

2. Close 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 meters of space. This is the scene of the wrong program, which is useless to us. Then open the registry, find the branch of HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ Current Version \ AE Debug, double-click the name of Auto key below it, change its "numerical data" to 0, and finally press F5 to refresh the setting to take effect, thus completely canceling its operation.

In addition, the memory.dmp that appears when the screen is blue can also be deleted. You can dump BSOD when you close it in My Computer/Properties.

3. Close System Restore: Right-click My Computer on the desktop, select Properties, and find System Restore. If you don't often install some software (are you better than me), you can also remove it, which can save a lot of space.

4. 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)

(blues note: I think hibernation is still very useful. )

5. 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 Windows XP automatically starts the service every time the system starts; "Manual" means that Windows XP 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 Windows XP and cannot be shut down, otherwise the system will crash. As for various services

We can view the function of 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.

6. Accelerate XP switching.

1) shortens the waiting time.

Open the Registry Editor and find HKEY _ Local _ Machine \ System \ Current Control Set \ Control.

Set WaitToKillServiceTimeout to: 1000 or less. (Original setting value: 20000)

Locate HKEY _ Current _ User \ Control Panel \ Desktop key and set it.

WaitToKillAppTimeout is changed to 1000 (original setting: 20000), that is, only wait 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.

2) Let the system automatically close 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)

3)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.

7. XP prefetcher

Windows XP comes with a service called Prefetcher, which initializes the management program when Windows starts, and the specified program can be loaded quickly in future use. By default, the prefetcher is on, but its performance can be further improved. Open Registry Editor and locate:

HKEY _ Local _ The current control settings of the machine system control the memory of the session manager.

ManagementPrefetchParameters, which has a key named EnablePrefetcher, and its value is 3 in most cases. The recommended setting value is 5. On my computer, it works best when it is set to 5. You can try different values at will until you find the one that suits you best.

You can also disable the prefetcher by setting the value to 0. However, unless it is for testing purposes, most people are not stupid enough to set it to 0.

8, compressed folder

This is a very good optimization. Windows XP has built-in support for. ZIP file, 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.

9. Don't load DLL files.

After the browser is used, some DLL files will be cached in memory for a long time, and a considerable part of memory will be occupied by unused DLL files. To prevent this, locate the following location in the registry:

HKEY _ Local _ Machine Software Microsoft Windows Security Edition Browser

Next, create a two-byte value named AlwaysUnloadDLL with the value of 1.

If you want to delete this optimization, just set the key value to 0 (or simply delete the key). Note: This optimization will take effect after Windows restarts.

10, completely turn off the file protection function of Windows XP. Use this trick with caution.

Find HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ current version \ Winlogon from the registry, and change the key value of "SFCDisable" to "FFFFFF9D". If you need to re-enable this feature, just reset it to "0".

1 1. Manually specify the process sequence to be viewed.

Press the Control+Alt+Delete key at the same time, and then click the "process" tab, and you will see a dialog box as shown in the above figure, where you can see all the processes currently running. If you want to allocate more process time for a program, such as 3D Studio Max, just right-click the process and move the mouse pointer down to "Set Priority >; (Set Priority) ",and then select the priority you want the program to have. When I receive an email, I will set 3DMAX as "standard", but when I leave the computer, I will upgrade its priority to the highest "real-time", so that the computer can process 3D actions more intently and quickly.

12. Turn off error reporting

Console-> System-> Advanced-> Lower right corner-> Error Report-> Close.

13. Speed up the display of windows: We can change the pop-up of windows from the taskbar by modifying the registry to minimize the action of returning to the taskbar. The steps are as follows: Open the Registry Editor and find the current HKEY user.

Control panel \ Desktop \ windowmetrics subbranch, and find the MinAniMate key value in the right window, with the type of REG_SZ. By default, the value of this key value is 1, which means that the animation displayed in the window is open. If it is changed to 0, animation is prohibited. Then, select the Logout command from the Start menu to activate the changes you just made.

14, remove the "update" option: For most users, the Windows Update function of Windows XP seems to have little effect, so we can remove it. The operating steps are as follows: Open the Registry Editor and find.

HKEY _ Current User \ Software \ Microsoft \ Windows \ Current Version \ Policy \

Explorer subbranch, select the "New" command under the "Edit" menu to create a new value of type REG_DWORD named NoCommonGroups. Double-click the newly created NoCommonGroups subitem, enter the key value "1" in the Edit String text box, and then click OK to restart the system.

15. Modify the login background mode of Windows XP: the monotonous login mode for a long time may make you bored. We can change it to your favorite pattern through the registration form. The steps are as follows: Open the Registry Editor and find the HKEY user. The Default \ ControlPanel \ Desktop subbranch, and double-click the wallpaper. Enter the path of the image you selected, such as: c: \ documents and settings \ my documents \ mypic.bmp, click "OK", then find the Tilewallpaper, double-click and enter the key value "1", and restart the system to see the effect.

16. Modify the background color when logging in: If you still want to modify the background color when logging in, you can follow the following steps: Open the registry editor and find the subbranch of HKEY _ User \ \. Default \ ControlPanel \ Colors, and double-click the background item name under the subitem branch to open the Edit String dialog box. Enter key values representing colors in the "Numerical Data" text box (for example, the RGB value of black is 000, the RGB value of white is 255 255 255, and the system default value is 5811kloc-0/65), and click "OK" to restart the system.

17. Set startup information or add warning information: If you want to display some personalized information defined by yourself when starting Windows XP, you can follow the following steps: Open the Registry Editor and find the subkey branch of HKEY _ Local _ Machine _ Software \ Microsoft \ Windows NT \ current version Winlogon. Double-click the key name of the LegalNoticeCaption below it, open the edit string window, enter the title of the information dialog box in the numerical data text box, such as "Hello, welcome to use this machine", then double-click the LegalNoticeText, and enter the warning information you want to display in the subsequent edit string window, such as "Please don't modify the settings at this level at will. , click OK, and then restart to see the modified effect.

18. Keep the desktop settings unchanged every time we 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 and find HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Police.

\Explorer subbranch, find the NoSaveSettings under it, with the type of REG_SZ, and change its key value to "0", or delete the key item directly, and restart the system to make the settings take effect.

19. Customize the button color at will: Although Windows XP itself has various window display schemes, users want to define the color of a certain part, such as changing the button color from black to blue or red, and then need to modify the registry. The steps are as follows: Open the Registry Editor and find the subbranch of HKEY _ Current _ User \ Control Panel \ color. Double-click Bottontext below it, change its key value to the value of the color you want in the opened dialog box, such as red 255 0 0, click OK, and restart the system to see the effect. At this time, the text color on the button will turn red, and you can also modify the parameters such as the width, height and background of the button.

20, modify the right mouse button menu

We know that the right mouse button menu can be modified through the registry in 98, but it can also be modified in WinXP. The method is as follows: Take adding "Browse here with DOS window" to the right mouse button menu as an example.

1) Open the registry editor, find HKEY _ class _ root \ directory \ shell, then select it, click the right mouse button, and create a new primary key, named DOS, then select a new primary key, double-click the default string value on the right, enter "Browse here with DOS window" in the pop-up dialog box, and then select a new primary key to create a new primary key. Name it "command", select the "command" primary key, and change the default value to "cmd.exe/k" CD% l ".

2) Check: Press the right mouse button on any folder, and you will see "Browse here with DOS window" in the pop-up menu. Choose to browse here with DOS window, press the left mouse button to see if the DOS window pops up!

2 1, modify the system ID number (ID number is very important in WinXP).

Under the general label in the system properties, we can see a series of numbers, such as: 55661-005-0809362-22169 and so on. This is the ID number. The ID number of each set of genuine WinXP is different (should you guess my purpose? ), then can we modify it? Of course (nonsense! If not, there is no need to write this article. Come with me and see what I can do!

The 1)ID number is stored in the registry. Mainly under these key values:

HKEY _ local _ machine \ software \ Microsoft \ Internet Explorer \ registered string ProductId.

String Product ID HKEY _ Local _ Machine \ Software \ Microsoft \ User Information/* If you are not registered in Microsoft, */

HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ The string ProductId of the current version.

HKEY _ Local _ Machine \ Software \ Microsoft \ Windows NT \ The string ProductId of the current version.

The above four digits are the key values of the ID stored in the registry, and should be modified at the same time. After the modification is completed, check the general label in the system properties to avoid the failure of modification and id recovery.

22, modify the version number:

There is an internal version number in About Windows (official version: 2600.xpclient.010817-148), and this version number is also stored in the registry, and the specific location is HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ Current Version, recorded by a string, can modify the version number of your XP by modifying this string named BuildLab.

23. Delete files from the hidden trash can.

The default location of the Windows XP trash can is in the lower right corner of the desktop, above the bottom system tray. If users open multiple windows, it will block the trash can, making it impossible for users to drag files and folders to the trash can. To this end, Microsoft has made a very humanized design. When the user drags a batch of files and moves them to the lower right corner of the desktop, the user can drag the mouse to move all the files to the blank area of the taskbar at the bottom of the desktop and stay there for a few seconds. At that time, all open windows will be automatically minimized, allowing users to drag files to the trash can. In addition, regardless of whether the multiple open windows are maximized or not, users can achieve the effect of minimizing all windows by performing the above operations.

24. Music catalog pictures can be set at will.

Windows XP provides many more advanced management functions than the previous Windows operating system, including album generator, which can automatically put album cover pictures into music folders saved by users (these music files are usually WMA files of Microsoft). Although this function is very convenient, there are some problems. For example, if some users previously transcribed some music CDs into MP3 format and saved them on their hard disks, although users can download CD covers from some music websites such as www.cdnow.com and www.amguide.com, they can only manually add these covers to each music folder one by one. This takes a long time, and once the user reinstalls the operating system, he will have to repeat the above complicated operations.

How to solve this problem? It's not complicated. When users download the cover picture of a music album, please save the picture file name as "folder.jpg" and put it in the corresponding music folder, so that Windows XP system will automatically default to the thumbnail picture of this folder, and if users play music files with Windows XP Media Player(MPXP player), the system will also automatically display the cover picture of the album. After this operation, there is no problem even if the user reinstalls the operating system in the future.

In addition, if users need it, they can also save a smaller picture file named "albumartsmall.jpg" when saving the above-mentioned "folder.jpg" file. The advantage of this is that if the user uses MPXP player to play music files, but the player's window is less than 200 X 200 pixels, the player can directly display this smaller picture. Otherwise, the player needs to process the folder.jpg and resize it to display it in a smaller window, which will naturally affect the speed of file calling.

25. Easily defragment the hard disk

After the computer is used for a period of time, the hard disk will produce a large number of file fragments, and users need to call the disk defragmenter regularly to clean it up. To this end, here is a method that can make it easier for you to call the defragmenter.

Users use Notepad to edit the registry import file named "context_defrag.inf" and enter the following contents in the file:

; Context _ Defragmentation. Medium-range nuclear force

; Add defragmentation to the right-click context menu of Windows XP.

[Version]

signature="$CHICAGO$ "

[Default Installation]

AddReg=AddMe

[Address]

HKCR, "Drive \ Shell \ Defragmentation \ Command",,, "Defragmentation. EXE % 1 "

After editing, right-click the file and select Install. After installation, a text menu will be added to the Windows XP operating system. When the user needs to tidy up the hard disk, open "My Computer", select the drive letter of the hard disk to be tidied up with the right mouse button, and select "defrag" in the pop-up text menu. At this time, the system will automatically call the built-in "defrag.exe" program to tidy up the hard disk.

If users need to delete the above information installed in the system registry, they can use regedit.exe Registry Editor to edit and modify it. The specific operation is to find the directory entry "HKEY _ class _ root \ drive \ shell", delete the "defragmentation" folder, and finally close the registry editor.

26. Clear the * * * enjoyment folder.

A rather unfriendly user interface of Windows XP operating system is to display all * * * shared folders in the upper part of the "My Computer" window. If users set more * * * shared folders, then every time they open the "My Computer" window, a lot of * * * shared folder information will be listed. How to delete these information displays? Use Registry Editor and find this primary key "HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Explorer \ My Computer \ Namespace \ DelegateFolders". Under this primary key, there is a name.

{59031a47-3f72-4a7-89c5-5595fe6b30ee} key, and delete key to clear those * * * folder information. The above changes can take effect without restarting.

27, display * * * enjoy setting label.

In Windows 2000 operating system, it is very simple for users to set the * * * enjoyment attribute of folders. Just right-click the folder and select Properties to see the * * * Enjoy Settings tab. However, it is complicated to set the folder * * * in Windows XP system, and users cannot see the setting label of * * * through the above operations. The specific modification method is as follows: open the tools in my computer, select folder properties, bring up the view tab, scroll to the bottom in the advanced settings section to cancel the selection before "Use simple file sharing (recommended)", and also cancel the selection if there is "Mickey Mouse" in the options bar. In this way, users can modify folder properties as easily as using Windows 2000.

28. Call the system sound scheme

Compared with the previous Windows operating system, Windows XP provides a better sound scheme, but the system does not call this scheme by default. In order to activate this scheme, we need to do the following: open the control panel, select the item "Sound, Voice and Audio Devices", find the taskbar of "Modify Sound Scheme", and select "Windows Default" in the opened dialog box. At this time, you will be prompted whether to save the previous sound scheme settings. You can choose No and click OK to finish the modification.

29. Speed up the display of the start menu.

The default display speed of the start menu in Windows XP system is slow, but users can speed up the display speed by editing the registration key value. The specific method is to open the registry editor and look for the primary key of "HKEY _ Current _ User \ Control Panel \ Desktop \ Menu Display Delay". The default value of the system is 400. Users can adjust the key value according to their own preferences, and the minimum value can be set to "0". If this method doesn't work, please select "Display Properties" in the control panel, select "Advanced" in "Display Effect" and deselect "Show menu shadows", which can speed up the display of the start menu.

30. Make the welcome window clearer.

The display effect of Windows XP system has been greatly improved, mainly because it adopts a clear technology called "ClearType", which makes users who use notebook computers and liquid crystal displays feel different effects from previous systems when running Windows XP operating system. However, because this cleaning effect can only be called after Windows starts, the welcome window at system startup still cannot achieve this effect. In order to make the welcome window clearer, users can use Registry Editor to modify and find these two primary keys.

"(default user) HKEY _ user \. Default \ Control Panel \ Desktop \ Font Smoothing

(string value) "and" HKEY user ". Default \ Control Panel \ Desktop \ fontsoftingtype.

(hexadecimal DWORD value) ",change the key value to" 2 ",so as to achieve a clear display effect.

3 1. It is forbidden to automatically call "Windows Messenger" at startup.

In order to promote Microsoft's instant chat program "Windows Messenger", the default setting of Windows XP operating system is to call this program when the system starts. But if you are not used to using this program, you can delete the key "HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Run \ MSMSGS".

32. Display "Hibernate" in the shutdown dialog box.

The default setting of Windows XP is that there is no option to put the system into hibernation in the shutdown dialog box, and the operation of displaying this option is very simple. When the shutdown dialog box appears, the user can press the "SHIFT" key at the same time, so the "Hibernate" option appears.

Second, hardware optimization.

1, memory performance optimization

There are several options to optimize memory performance in Windows XP, which are located under the registry: HKEY _ Local _ Machine \ System \ Current Control Set \ Control \ Session Manager \ Memory Management.

1) disables the paging executor.

Under normal circumstances, XP will write the fragments in memory to the hard disk. We can prevent it from doing this and save the data in memory, thus improving the system performance. It should be noted that users with large memory (above 256M) can use this setting. The name of this setting is just like its function, and it is called "DisablePagingExecutive". Changing its value from 0 to 1 can disable memory page scheduling.

2) Improve the system cache: change the key value of LargeSystemCache from 0 to 1, and Windows XP will allocate all system memory except 4M to the file system cache, which means that XP kernel can run in memory, greatly improving the system speed. The remaining 4M memory is used for disk cache, and XP will allocate more if necessary under certain conditions. Generally speaking, this optimization will greatly improve the system performance, but it may also reduce the performance of some applications. As mentioned above, you must have more than 256M memory to activate LargeSystemCache, otherwise don't touch it.

3) Input/output performance: This optimization is only meaningful to server users-it can improve the performance of the system when transmitting large files. By default, this key does not exist in the registry, so you must create a DWORD (double-byte value) key and name it IOPageLockLimit. When using this optimization, most people find that the performance is the best between 8 and16 MB bytes. You can set any specific value and try to see which value can get the best performance. Remember that this value is calculated in bytes, so, for example, if you want to allocate 12M, it is12 *1024 *1024, which is 125829 12. Just like the previous memory optimization, you can only change the value here when the memory is greater than 256 mm.

2. Turn on DMA: Select IDE ATA/ATAPI controller in Device Manager, enter the advanced settings of main/auxiliary IDE channels, set all transfer modes to use DMA (if any), and the system will automatically turn on DMA support (also set it to support DMA in BIOS first).

3. Turn off the automatic operation function of the optical drive in XP: turn on my computer. Under Removable Storage Devices, right-click the CD-ROM drive, and then click Properties. See the "AutoPlay" label? Change it yourself.

4. Setting CPU:Windows XP cannot automatically detect the second-level cache capacity of the processor, so we need to set it manually in the registry. First, open the registry (enter "Regedit" when operating), and then open:

HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \, select "SecondLevelDataCache" and set it according to the processor you use. For example, PIII· Copamin/P4 Willamette is "256", Athlon XP is "384" and P4 Northwood is "5 12".

5. When 5.XP installs the driver, a window often appears, saying that this program has not been verified by Microsoft. We can sign the driver in Control Panel-System-Hardware-Device Manager. See the options? Know what to do.

6. Prioritize IRQ interrupt requests

Every major part of the computer has an IRQ interrupt number. This is to achieve the optimization goal by modifying the priority of each IRQ request. The main optimization object here is the system /CMOS real-time clock, which improves the performance through the motherboard. First, determine which component you want to achieve higher performance, and then find the IRQ interrupt number that this hardware is using. How to find it? Open the system properties in the control panel (or press the Windows+Break hotkey combination on the keyboard to open it). Select the Hardware tab, and then click the Device Manager button. Right-click the component for which you want to check the IRQ number, select Properties, and then click the Resources tab. Here you can see the IRQ interrupt number that the device is using (if there is no IRQ interrupt number, please select another device). Write down the interrupt number, and then run the registry editor regedit to find the location of HKEY _ local _ machine \ system \ current control set \ control \ priority control in the registry. We need to establish a DWORD double-byte value called IRQ#Priority (where "#" is the specific IRQ interrupt number) here, and then set its value to 1. For example, the IRQ interrupt number of my system CMOS real-time clock is 8, and the key name I want to establish is IRQ8Priority. After restarting the computer, you will find that the performance of the newly optimized components has improved. I strongly recommend this method to optimize the system CMOS real-time clock, because it can improve the performance of the whole motherboard. Of course, the priority of multiple IRQ interrupt numbers can also be increased, but the effect is not very good, and the system may be unstable. If you want to undo this optimization setting, just delete the registry key you just created.

Third, network optimization:

1, speed up * * * enjoyment: this is a great optimization. Before I found this optimization, my scalp often cracked when I waited for the window to display the * * * enjoy directory on other computers. Usually, when Windows XP connects to another computer, it will check all scheduled tasks on the other computer-this is really unnecessary, it will make you wait for 30 seconds, which is too bad. Fortunately, it is easy to ban this process. First, find HKEY _ local _ machine \ software \ Microsoft \ Windows/ current version \ resource manager \ remote computer \ namespace in the registry. In this regard, there should be a

{d6277990-4c6a-11cf-87-00aa0060f5bf} key. Delete it directly. After restarting the computer, Windows will no longer check the scheduled tasks, and the speed will be significantly improved!

2. Solve the pause problem during the execution of WinXP.

Start-Network Connection-Local Connection, right-click, select Properties, select "TCP/IP", click Properties, and use the following IP address:192.168.0.1,subnet mask: 255.255. ...

3. How to make XP automatically connect to the Internet:

IE- Tools-Internet Options-Connect, check "Dial when the network does not exist" and pull IE to "Start".

Every time you turn it on, you are online! There is another way:

Enter the connection content, uncheck "Prompt for name, password, certificate, etc.", and then connect it.
