Run the registry editor, find "HKEY _ local _ MACONE \ system \ control set 00 1 \ control", change the key value of SystemStartOptions in the right window to NODETECE, save and exit. (Used)
2. Disable redundant service components
Right-click "My Computer" and select "Properties-Management-Service Application-Service" option. You can see various program components loaded on Windows XP. Many services are simply unnecessary. You can disable these service components to speed up system operation. Select properties, click Stop, and set the startup type to Manual or Disabled.
Note: Some services are necessary for Windows XP, and the system will crash after shutdown. We can double-click the service or hover over its description to ensure that it is not needed before it is banned.
Some services are necessary for Windows XP and cannot be shut down, otherwise the system will crash.

3. Close the debugger, Dr. Watson.
Dr.Watson is a crash analysis tool of Windows XP, which will automatically pop up when the application crashes. By default, the memory related to the error will be saved as a dump file for programmers to analyze. However, recording dump files will not help ordinary users, but will bring great inconvenience: because Dr. Watson will record the memory when the application crashes, it will take a long time to read and write from the hard disk, and it will take a long time to close the program, and dump files will take up a lot of disk space.
Close the debugger Dr. Watson: run drwtsn32 and 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. In addition, the memory.dmp that appears when the screen is blue can also be deleted. You can turn off the dump when you turn off BSOD in My Computer/Properties. To close Dr.Watson, you can open the registry editor, find the branch of "HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ current version \ AEDebug", double-click the Auto key name under it, change its "numerical data" to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. Similarly, we can cancel all options with debugging function when the screen is blue, such as memory.dmp. We can select the Advanced tab in the system properties dialog box, click the Settings button in the startup and recovery column, and select "Write debugging information" as "None" in the startup and recovery dialog box that pops up.
4. Turn off system backup. Right-click my computer, select Properties, and under the System Backup tab, select Turn off system backup for each drive, which can save a lot of hard disk space. (Used)
5. Optimize system properties
Right click on my computer. Under the "Properties-Advanced-Appearance Effects" tab, you can choose the appropriate appearance according to the machine and your own performance. (Used)
Under the Advanced tab, select the application under application response and the application in memory use, so that the system will allocate more resources to the foreground program to make it run faster.
Select the change option under Virtual Memory under the Advanced tab, and set the value of virtual memory to 2.5 times of your physical memory, and the maximum value is the same as the minimum value; And try to avoid setting virtual memory on the same partition as system files. (Used)
6. Invalidate the reading ability of ZIP documents
By default, Windows XP turns on support for ZIP files, which takes up some system resources. You can choose Start → Run, type "regsvr32/u zipfldr.dll" in the Run dialog box, and press Enter to cancel XP's support for zip decompression, thus saving system resources.
7. Clear the page file when closing.
Open the control panel, click Administrative Tools → Local Security Policy → Local Policy → Security Options, double-click the "Shut Down: Clean up Virtual Memory Page Files" item, click the "Enable" option in the pop-up menu, and then click "OK". (Used)
8. Use a simple interface
Although the default appearance scheme of Windows XP is beautiful, it also takes up a lot of system resources, so it can be changed into a classic appearance to get better performance.
Right-click an empty place on the desktop and select the "Properties" command from the pop-up shortcut menu to open the "Display Properties" dialog box. Select "Windows Classic" as the theme on the Theme tab, and change the appearance to a more economical Windows Classic appearance.
9. Speed up the menu display.
Run the Registry Editor and enter "HKEY _ Current _ User \ Control Panel \ Desktop" to change the data value named MenuShowDelay from the original default value of 400 to 0. After the modification, the display speed of XP start menu and even the menu of application software will be obviously accelerated.
10. Accelerated window display
We can change the pop-up of the window from the taskbar and minimize the action of returning to the taskbar by modifying the registry. The steps are as follows: Open the Registry Editor, find the subbranch of HKEY _ Current _ User \ Control Panel \ Desktop \ windowmetrics, and find the MinAniMate key value in the window on the right, 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 will be prohibited. Then, select the Logout command from the Start menu to activate the changes you just made. (Used)
1 1. Enable DMA transfer mode.
The so-called DMA, that is, direct memory storage mode, means that computer peripherals (mainly hard disks) can directly exchange data with memory, which can speed up the reading and writing speed of hard disks and improve the speed of data transmission.
Open the system properties dialog box, select the device manager button in the hardware tab, open the device manager window, select the IDE ATA/ATAPI controller in the device list, double-click the main IDE channel or the auxiliary IDE channel, and check whether DMA mode has been started in the advanced settings tab of its properties dialog box. Generally speaking, if the device supports it, it will. (This machine has been set automatically)
12. Reduce the pre-reading and waiting time of the progress bar.
A progress bar will appear when Windows XP starts. We can modify the registry so that the progress bar will enter the login screen only once.
Select the Run command from the Start menu, type the regedit command in the Run dialog box, and then press enter to start the Registry Editor and look for:
HKEY _ LOCAL _ MACHINE \ system M \ current Control set \ Control \ Session Manager \ Memory
Management\PrefetchParameters, select the EnablePrefetcher key under it and change its key value to "1". (Used)
13. Reduce the waiting time for scanning the startup disk.
When the restart caused by abnormal shutdown or crash is recorded in the Windows log, the system will automatically run ScanDisk at startup. By default, each partition will wait 10 seconds before scanning. If each partition has to wait 10 seconds to start scanning, plus the time required to scan itself, it will take a long time to complete the startup process. In this case, we can set the waiting time for canceling disk scanning, or even prohibit scanning disk partitions.
Select "Start → Run" and type "chkntfs /t:0" in the run dialog box to set the waiting time of disk scanning to 0; If you want to ignore scanning a partition, such as drive C, when the computer starts, you can enter the command "chkntfs/x c:"; If you want to resume the scanning of drive C, you can use the command "chkntfs /d c:" to restore all the default settings of chkntfs except automatic file check countdown.
14. Set the processor L2 cache capacity.
Windows XP cannot automatically detect the processor's L2 cache capacity, so we need to manually set it in the registry. First, open the registry and find:
"HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management", select "SecondLevelDataCache" under it 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". (Used)
15. Change the visual effect
Windows XP enables almost all visual effects by default, such as fading in and out and showing shadows under menus. Although these visual effects are beautiful, they will have a certain impact on the system performance, and sometimes even lead to the suspension of application software. Generally speaking, it is recommended to use less or cancel these visual effects.
Select the "My Computer" icon on the desktop, click the right mouse button, and select the "Properties" command in the shortcut menu to open the "System Properties" dialog box. Select the Advanced tab and click the Settings button in the Performance column to open the Performance Options dialog box. You can turn off all visual effects by selecting the "Adjust to Best Performance" radio box, or select "Customize" and then select the visual effects you want.
Open the System properties, open the Advanced tab, click the Settings button in the Performance column, and then open the Performance Options dialog box. After you select Custom in the Visual Effects tab, only the following will be retained: Smooth screen font edge, Use background picture for each folder type, Show semi-transparent selection rectangle and In window. "Use common tasks in folders" and "Use shadows for icon labels on the desktop". Don't check the others. Click "OK" to exit after setting.
16. Reasonable setting of page virtual memory
Also in the Performance Options dialog box, select the Advanced tab, click the Change button in the Virtual Memory column, select the virtual memory as the custom size, and then set its value. In general, it is advisable to set the virtual value to not less than 256M and not more than 382M, and the maximum and minimum values are the same. (You can also consider setting it to 2 times the physical memory, which is better. )
17. Turn off unused equipment.
Windows XP always tries to install and manage drivers for all devices of the computer, which will not only slow down the system startup, but also cause a lot of system resources. In view of this situation, you can disable devices that are not commonly used, such as PCMCIA cards, modems, infrared devices, printer ports (LPT 1) or serial ports (COM 1), by double-clicking the device to be disabled and selecting Do not use this device (disable) in the General tab of its Properties dialog box. Settings will take effect when you restart, and then enable these devices from Device Manager when you need to use them. (printer port (LPT 1) or serial port (COM 1) is used.
18. Turn off error reporting
When the application fails, a window will pop up to send an error report. In fact, such an error report is almost meaningless to ordinary users, and it is a wise choice to close it.
Select the Advanced tab in the system properties dialog box, click the Error Reporting button, select the Disable Error Reporting option in the Error Reporting dialog box that pops up, and finally click OK.
In addition, we can turn off error reporting from the group policy: type gpedit.msc from Run, run the group policy editor, expand the computer configuration → management template → system → error reporting function, double-click the report error in the setting bar on the right, and select the disable radio box in the pop-up properties dialog box to disable error reporting.
19. Eliminate menu delay
Removing the delay when the menu pops up can speed up XP to some extent. The location of the key to be modified is "HKEY _ Current _ User \ Control Panel \ Desktop". Modify the "MenuShowDelay" key under it, change the default 400 to 0, and press F5 to refresh the registry to take effect. (revised to 50)
20. Clear the pre-read file
Although the pre-reading setting of Windows XP can improve the system speed, after a period of use, the number of files in the pre-reading folder will become quite large, resulting in a longer system search time. Moreover, some applications will produce dead-chain files, which will increase the search burden of the system. So these pre-read files should be deleted regularly. The expected files are stored in the Prefetch folder of the Windows XP system folder, and all files under this folder can be deleted.
2 1. Turn off the autoplay function.
In Windows XP, when a CD is inserted into a CD-ROM drive or USB hard drive and connected to a computer, the system will automatically scan the CD-ROM drive or USB hard drive and prompt you whether to play pictures, videos, music and other files inside. If it is a large-capacity USB hard disk with multiple partitions, the scanning time will be longer, and it is very troublesome to manually close the prompt window several times. In this case, we can turn off the automatic playback function of Windows XP.
Run the group policy program. In the left column of the Group Policy window, open the computer configuration, select the system under the management template, then find "Turn off autoplay" in the configuration column on the right, and double-click it to open the "Turn off autoplay properties" dialog box. Select Enable in the Settings tab, and select All Drives in the Turn off AutoPlay drop-down list. In this way, you don't have to worry about the trouble caused by the "automatic play" function of Windows XP in the future.
22. Accelerate the closure
The shutdown speed of Windows XP is slower than the startup speed, especially some tasks need to be completed manually, which further delays the shutdown speed. Therefore, to speed up the shutdown, we must first turn on the automatic task ending function of Windows XP. The specific steps are: find "HKEY _ Current _ User \ Control Panel \ Desktop" from the registry, and set the key value of "AutoEndTasks" to 1.
Then change "HungAppTimeout" to "4000 (or less, this machine has been set to 1000)" (the default is 5000), and the key value is also under "HKEY _ Current _ User \ Control Panel \ Desktop"; The last step is to find "HKEY _ Local _ Machine \ System \ Current Control Set \ Control" and set WaitToKillServiceTimeout to "4000" (this machine has been set to1000); After this setting, the shutdown speed is obviously accelerated. (Used)
Second, XP slimming
23. Delete the system file backup
There are nearly 250MB files in the "system32\dllcache" directory of system files. Are they windows? Backup of XP system files. When the system files of Windows XP are replaced, deleted or modified, Windows XP can automatically extract the corresponding system files for recovery, thus ensuring the stability of the system. You can't delete the folder directly, but you should enter the Sfc.exe/Purge cache command at the command prompt to clear it.
24. Turn off hibernation support
Hibernation takes up a lot of hard disk space. If you use it less, you might as well open the control panel, double-click the power option, select the Hibernation tab in the pop-up power option properties dialog box, uncheck the Enable Hibernation checkbox, and turn off the * * * function.
25. Clear temporary files
(1) Clear temporary system files.
The temporary files of the system are generally stored in two locations: a temp folder under the Windows installation directory; The other is the X:\Documents and Settings\ "user name \ local settings \Temp folder (x: the partition where the system is located). Files in both locations can be deleted directly.
(2) Remove temporary Internet files
Long-term surfing the Internet will produce a large number of temporary surfing files, and regular deletion will save a lot of hard disk space. Open IE browser, select Internet options from the Tools menu, select the General tab in the pop-up dialog box, click the Delete File button in the Internet Temporary Files column, select the Delete All Offline Content checkbox in the pop-up Delete File dialog box, and click OK.
You can also set the disk occupied by temporary Internet files within an acceptable range, click the "Settings" button in the "Temporary Internet Files" column, and then set the disk space occupied by temporary Internet files in the "Settings" dialog box, or move the folder of temporary Internet files to another partition to reduce the disk occupation of the system partition.
26. File compression in 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.
27. Removable files
(1)% systemroot% \ drivercache \ Here are the drivers that come with the operating system, about 50 megabytes. If you remove them, you will need the operating system CD when installing new hardware in the future.
⑵ 3:% systemroot% \ helpBelow is help. If you never care about help, delete it, with 30 megabytes. If %systemroot% has a folder that starts with a $ sign like $NtUninstall$, it is a backup left when the patch is installed, or it can be deleted. Nobody will fall back anyway. (Used)
⑶ The% systemroot% \ system32 \ dllcache used by the system to protect important system files is at least about 200 megabytes. If you delete it directly or use sfc /purgecache to clear it, there will be no serious consequences, and there will be no annoying prompt "System file has been replaced".
Third, network optimization.
28. Release 20% of the network bandwidth occupied by QoS packets.
Windows XP's built-in QoS package needs to occupy 20% of the network bandwidth, but we can release this part of the bandwidth. Open the group policy window, expand computer configuration → management template → network →QoS packet scheduler in the left column, then double-click the limit reserved bandwidth in the right window, set the limit reserved bandwidth to enabled in the settings tab of its properties dialog box, and then set the bandwidth limit to 0 in the bandwidth limit column below.
Cancel the 20% network restriction.
Run gpedit.msc, open the group policy, click Computer Management-Management Template-Network -QoS Package High Program, and double-click "Limit Reserved Bandwidth" on the right to set it.
29. Enjoy a quick browse of the LAN.
Usually, when connecting to other computers, Windows XP checks all scheduled tasks on other computers. This check will make you wait for 30 seconds or more. The deletion method can be found in the registry: HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Resource Manager \ Remote Computer \ Namespace ". Under this key value, there will be a key {d6277990-4c6a-11cf-87-00aa0060f5bf}. After deleting and restarting the computer, Windows XP no longer checks the scheduled tasks, and the speed is obviously improved.
30 .. Improve the transmission rate of 10/ 100M network card.
Select Start → Connect to → Show all connections, double-click the connection used by the network card, click the Properties button, open the Properties dialog box, and select the Advanced tab. Select Link Speed/Duplex Mode in the property column, and then change Auto Mode to 10 Half-duplex Mode in the setting value column. In this way, the attribute of 10/ 100M adaptive network card is manually forced to 100M half-duplex mode, there is no automatic negotiation between network cards, and data transmission between network cards is always carried out at the speed of 10Mbps, which greatly improves the transmission efficiency between networks. This setting is only valid for some network cards. (Used)
Fourth, my XP is personalized.
3 1. Remove the arrow from the shortcut icon.
Click the Start menu, click Run, and enter "Regedit.exe" in the dialog box to open the Registry Editor. Open HKEY- local-machine \ software \ class \ lnkfile or HKEY- local-machine \ software \ class \ pigfile. There is a project "IsShotcut" in both folders. Delete it in the window on the right side of Registry Editor, and then restart your computer. (Used)
32. speed up Win XP browsing!
Open the registry and click:
HKEY _ local _ machine/software/Microsoft/Windows/current version/explorer/remotecomputer/namespace.
Select key values by column: {d6277990-4c6a-11cf-8d87-00aa0060f5bf}
33. Eliminate mistakes in payment applications.
Restore the "registry" before the problem, and then reinstall "Media Player 9" or "Media Player 10" and it's ok!
V. Other skills
34. The registry is "double-opened"
Sometimes it is necessary to open multiple registry editor windows for comparison, and then edit the registry, but the repeated operation of the "regedit" command can only open the same registry editor window, that is, if you have already opened a registry editor, you can't open the second one, but you may not know that regedit has a hidden parameter m, so we can use the "regedit -m" command to open a new one.
36. Refuse to run the Desktop Cleanup Wizard.
According to the default settings of the system, the system will remind you to clean the desktop every 60 days. If you don't want to be prompted, you can open the Group Policy Editor by running gpedit.msc, navigate to User Configuration → Manage Templates → Desktop, and set the Delete Desktop Cleanup Wizard to be disabled. Or right-click a blank space on the desktop, select the Properties menu, switch to the Desktop tab, click the Customize Desktop button, and uncheck Run Desktop Cleanup Wizard every 60 days. If you want to clean your desktop in the future, you can click the "Clean Desktop Now" button here to clean it manually.
37. Solve the problem of software incompatibility
The kernel of Windows XP is very different from that of Windows 98. Software that can be installed and run under Windows 98 may not run under Windows XP. Fortunately, Windows XP has a compatible mode to virtualize other operating systems, and can simulate Windows 95/98/2000 and so on. The method is: drag the installation file of the software that cannot be installed to the Windows XP desktop, then right-click the file icon, select the "Properties" option, and select the required operating system compatibility mode to install the software normally.
38, modify the folder icon
Windows folders are almost all faces. If your favorite cpu and memory are large enough, you can consider personalized folder icons. Specific operating steps: right-click the folder where you want to modify the icon, then click Properties, select Custom, click Change Icon (I)…, press the icon available in the system, or click Browse to select the icon in the folder where the icon is stored, and finally click OK. You can find it online, a lot.
39, speed up the shutdown
(1) Use Shutdown.exe to close.
Shutdown.exe is located in the folder C:\Windows\system32 (drive C is the system disk). We can create a shortcut for it on the desktop to close it quickly. The method is as follows: first create a shortcut, then right-click, select Properties, and add "-s -t 10" after the path of the target text box. Where "-s" stands for turning off the computer, but it can also be changed to "-r" for restarting; "-t" means to set the countdown, that is, the following number 10 means 10 second, which can be set according to your own needs.
In addition, there is "-c shutdown prompt message", which means that the shutdown prompt message can be set, but it cannot exceed 127 characters.
⑵ Use the task manager skillfully.
Press "Ctrl+Alt+Del" to bring up the task manager window, press and hold the "Ctrl" key to activate the "Shutdown" menu, and then select the "Shutdown" or "Restart" menu item. You will find that the shutdown speed can be said to be instantaneous.
40. Six Taboos of Using WinXP
(1) Avoid virtual optical drives.
At present, most virtual CD-ROMs are unstable in XP, which easily leads to XP crash, because virtual CD-ROMs are different from ordinary software: they fool Windows in the device manager through a special mechanism, making Windows think that a physical CD-ROMs have been added. XP only designed the driver to restore the hardware, but did not expect to "restore/delete" the hardware itself. Because XP is specially optimized for NTFS and network, and most virtual optical drives are developed in FAT32 environment, there are few virtual optical drives compatible with XP at present. If you must install them, you have to endure several crashes to try which one is stable, otherwise XP may crash.
In particular, I want to remind you that even if you find a stable virtual CD-ROM software, if you virtualize more than four physical CD-ROMs, it may trigger the activation check mechanism of XP and require you to reactivate XP-because Microsoft thinks that you may have changed four hardware machines, it is recommended that you do not install virtual CD-ROMs. If you really want to use a virtual CD-ROM drive, you'd better use more operating systems, and you'd better install 98 in it. It seems that only when the developer who wrote the virtual CD-ROM software wrote a new version that can run stably and will not lead to activation can the virtual CD-ROM be used smoothly.
(2) Avoid invalid dates.
XP also has a date checking mechanism that matches the activation check. If the CMOS battery of your motherboard is dead, or other date restriction software is misused or used, resulting in invalid date1999 (XP has not been developed in1999), then XP will lock the system in the word "Welcome" after initializing the graphical interface, without any prompts and options, except that the mouse can move, just like a crash. If you don't pay attention to the influence of the date, no matter what you do, you can't fix XP, so the author reinstalled XP at a loss, and later found out the real reason-so be careful about the date when you started XP.
