1. After all kinds of software and hardware are installed properly, delete the system backup files: Start → Run → sfc.exe/Purge Cache is nearly 300 m.
2. Delete the driver.cab file in the driver backup: %windows%\driver cache\i386 directory, usually this file is 76M.
3. Delete for help, nearly 4xM.
4. After upgrading, you will find that %windows%\ has many directories similar to $ ntuninstallq311889 $,10~30M ~ 30m. Remember to delete after each online upgrade.
5. If there is win2000/server in the hard disk, you can point all the pagefile.sys files to the same place: Control Panel → System → Performance → Advanced → Virtual Memory → Change. Note that the key "Settings" will take effect.
6. Uninstall uncommon components: use Notepad to modify \%windows%\inf\sysoc.inf, use the find/replace function, enter and hide in the find box, and replace all with blanks. Run Add-Remove program after saving, and you will see more options in Add/Remove Windows components. Delete games, code watches and other unused things.
7. Delete the input method not used under \windows\ime, 80M. Delete all folders except "CHSIME" and "SHARED". (If it cannot be deleted, it can be deleted in safe mode). Please make sure that you have deleted all system file backups in advance, otherwise they will be automatically restored from the backup files.
8. If the space is very tight, please enable the compression function of NTFS, which can also save 2% of the space. (Not recommended for beginners)
9. Turn off System Restore, right-click my computer on the desktop, select Properties, find System Restore, and then select Turn off System Restore on all drives.
10, service package backup file. I saw a folder similar to "ServicePackFiles" in the Windows directory, which saved the backup files after installing the Service Pack. Delete only the files in it, not this folder.
1 1, hide the folder after Windows update. The name is "$ ntuninstallq * * * * * $”(* * * * is a number), and these folders hold backup files of patches you installed through Windows Update. You can delete it directly. Note: These document shelves are hidden.
12, temporary folder. On the Advanced tab of the System Properties dialog box, click the Environment Variables button, and then reassign the positions of the two variables "TEMP" and "TMP" in the window. It should be noted that there are two kinds of environment variables: the environment variable of the current user and the system variable, which are set in the same way. Select each variable, and then click Edit to re-specify the variable value (the variable value here refers to a new path, such as d:\temp). It takes effect after restarting the system.
13, disable hibernation. Windows XP is enabled by default, open the Display Properties dialog box, and then click Screen Saver.
Click the Power button on the Protector tab to open the Power Properties dialog box, then open the Hibernation tab and deselect Enable Hibernation. After confirmation, the new settings will take effect immediately.
14, transfer IE cache. Open the Internet Options dialog box under the IE Tools menu, and then click Settings under Temporary Internet Files. If you don't plan to use IE cache, please drag the Used Disk Space slider to the far left, otherwise you can click the Move Folder button to allocate IE cache to a hard disk partition other than the system disk.
15. Transfer my file. Right-click the My Documents folder, then select Properties to open the Properties dialog box, and click Move Directly to transfer My Documents to another partition.
16. Turn off the memory dump. In the System Properties dialog box, under the Advanced tab, click the Start and Resume button, and then select None from the Write Debugging Information drop-down menu. And you can search all *. Dmp files and delete them. At the same time, enter "drwtsn32" during the running process, and press Enter to open the tool of Dr. Watson, in which the selections of "Dump all thread contexts", "Append to existing log file" and "Create fault dump file" are cancelled.
Second, turn off some useless functions of windows xp.
1, c:\windows\cursors\, this folder contains all mouse pointers, if you only intend to use windows default.
Mouse pointer, and then you can delete all the files here.
2.c:\windows\inf\, this folder contains a large number of hardware drivers under windows, and the files in it can be deleted (if the hardware is changed in the future, please don't delete it! Do you want to be very troublesome! )
3.c:\ Windows \ srchast, this folder stores the search assistant of Windows XP, which will appear when you search for files.
A puppy or other character. You can delete the folder directly, so you will use the classic Windows 2000 mode.
Search method, instead of XP asking if you want to search for photos or music.
4. C: \ Windows \ Downloaded Installations \, this folder stores installation files of some programs (mainly programs installed by using Windows Installer technology), so that if this program needs to be repaired or other operations in the future, it can be completed directly through the installation files saved here. However, emptying this folder usually does not have much impact on the use of the system, and it is recommended to delete it.
5.c:\windows\media\, this system sound is used to save windows, and it can be deleted directly if it is not needed.
6.c:\windows\system32\restore\, this folder stores executable files restored by the system. If you don't plan to use the system restore function at all, you can delete all the files here. Before deleting, it is best to turn off System Restore and run it.
Services.msc closes the System Restore service, and then deletes all restore points.
7.c:\windows\system32\usmt\, this folder is related to files and settings transfer wizard, if you don't use it.
This function can also empty folders.
8.c:\program files\msn，c:\program files\netmeeting\。 These two folders are executable files of MSN Explorer and Netmeeting, which can be emptied if not needed.
9.C:\windows\system32\oobe, here is the wizard when you log in for the first time after installing XP, just like Windows XP.
Some programs are activated for the product. If you use XP as the enterprise edition and don't need to activate it, you can empty this folder (yes, but not).
Is to delete the folder); And if your Windows XP is a retail version or an OEM version, you'd better not touch it.
10, c: \ windows \ msgent, all the files of the agent are saved here, and the agent here is just like the Microsoft Office application.
Like the office assistants in the preface, they are all dynamic cartoon images. Usually we don't need these things, we can delete them.
1 1, c:\windows\java, Microsoft's java virtual machine. If you have installed Sun's virtual machine or can't use it at all.
To the JAVA program (this possibility is very low, because many web pages also use JAVA), you can delete this folder.
If the system disk space is still tight, you can use NTFS partition compression. First, make sure that your system disk is an NTFS file system.
Then open "My Computer", right-click the icon on the system disk, select "Properties", and then select "Compress the drive to save disk space" to make sure that the operating system will compress all the data on the system disk. After this compression, the system will run slower in the future.
Third, the system accelerates.
1, modify the Run key of the registry, and remove those things that are not commonly used, such as Windows Messenger. The specific method is: Start →
Run →Regedit to "h _ c _ u \ software \ Microsoft \ windows \ currentversion \ run \ msmsgs"/background.
Just delete this key value. Of course, you can also remove the startup plug-in through Msconfig.
2.Windows XP uses the new technology of pre-reading settings to improve the system speed. Start → Run →regedit at
There is an EnablePrefetcher key under h _ l _ m \ system \ currentcontrolset \ control \ sessionmanager \ memorymanagement \ prefetch parameters. Just change its value to "1".
Note: The values of EnablePrefetcher can be set to 0, 1, 2 and 3. 0- disable, 1- read application, 2- start pre-reading, 3- read the first two (recommendation 3, if you want to start faster, choose 1, 0 is not recommended).
3. Turn off the special effects in the system properties, which is a simple and effective acceleration method. Click Start → Control Panel → System → Advanced → Performance → Settings → In the visual effect, adjust the settings to the best performance → OK. In this way, the desktop will be very similar to win2000. I still like the blue window of XP, so I checked "Use visual styles on windows and buttons", "Use common tasks in folders" and "Use shadows on icon labels on the desktop", so that I can see a beautiful blue interface and speed up the process.
4. ZIP support for Windows XP can be said to be chicken ribs. Click start → run, type: regsvr32/u zipfldr.dll, and then press enter to run. The sign of success is that a prompt window appears, and the content is roughly as follows: Dll UnrgisterServer in zipfldr.dll is successful.
5. There is a Qos system service in 5.Windows XP, and this scheduling will occupy a certain network bandwidth. Start menu → Run → Type
Gpedit.msc, the group policy window appears, expand Management Templates → Network, expand QoS Packet Scheduler, right-click Restrict Reserved Bandwidth in the right window, and there is Restrict Reserved Bandwidth in the settings in the properties. Select Disable, and then click OK. After completing and applying the above modifications, if users can see "QoS Packet Scheduler" in the general properties tab of the properties dialog box of network connection. It means that the modification is successful, otherwise it means that the modification has failed. By the way, the Qos protocol in the network properties has also been uninstalled. Of course, you can also achieve the same goal by disabling Qos services.
6. Enjoy browsing the LAN quickly. Usually, when another computer is connected, Windows XP will thoroughly check the other computer.
For all scheduled tasks, this check will make you wait 30 seconds or more. The method is Start → Run →Regedit→
HKEY _ LOCAL _ MACHINE \ Software \ Microsoft \ Windows \ Current Version \ Explorer
\ Remote Computer \ Namespace. There will be a key {D6277990-4C6A-1CF-87-00A0060F5 BF} under this key value, and it will be deleted.
Reboot takes effect after falling!
7. Close the debugger Dr.Watson. Dr.wtsn32 is a program error debugger, which will occupy some system resources.
H _ l _ m \ software \ Microsoft \ windows nt \ currentversion \ aedebug subbranch, and double-click the Auto key value below it.
Name, change its "numerical data" to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. Along this line of thought, I
Users can cancel all options with debugging function in "My Computer → Properties → Advanced → Settings" when the blue screen appears, such as memory.dmp.
Settings → Write debugging information → Select None ".
8. Turn off error reporting: click Control Panel-> System-> Advanced-> Error Reporting->; Disable error reporting-> ok, that's it!
9. Automatically end the unresponsive task when it is turned off, and set ""in HKEY _ Current _ User \ Control Panel \ Desktop.
Just change the key value of "AutoEndTasks" to "1".
10. Turn off automatic update Yes, right-click my computer, click Properties, click automatic update, and then select Turn off automatic update in the notification settings column. I will update my computer manually.
1 1. Reduce the waiting time for scanning the startup disk, start → run, and type "chkntfs/t:0", indicating that the waiting time is 0 seconds.
12. Modify the secondary cache of CPU. Under normal circumstances, XP will automatically identify the second-level cache of CPU. But sometimes XP doesn't do this,
This requires manual optimization to improve the performance of CPU. Find h _ l _ m \ system \ currentcontrolset \ control \ sessionmanager \ memorymanagement \ secondleveldatacache and modify its decimal system according to your CPU. The secondary cache values of common CPUs are as follows:
AMD duron: 64 (kb);
Celerona/Celerona 2:128;
PII Mobile /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;
It's best to look at the specific amount of secondary cache of your CPU before setting it, and the restart will take effect.
13, modify the disk cache to speed up XP. Disk cache plays a vital role in XP operation, but the default I/O page file ratio is
More conservative. Therefore, it is a good practice to use different disk caches for different memories. find
h _ L _ M \ SYSTEM \ current Control set \ Control \ Session Manager
\ memory management \ IoPageLockLimit
Modify its hexadecimal value according to your memory (the value is calculated in bytes):
64M: 100000； (equivalent to 1M)
128m:400000； (equivalent to 4M)
256m: 1000000； (equivalent to 16M)
More than 5 12M: 4,000,000; (equivalent to 64M)
When you set it to 0, it will be automatically configured and the restart will take effect.
14. Clear the read-ahead file. When XP is used for a period of time, the files in the pre-read folder (c:\windows\prefetch) will become very large, and there will be dead-chain files in it, which will slow down the system. It is recommended to delete these files regularly.
15. Unnecessary system sharing and C$ and D$ management sharing are prohibited.
For server: find a new DWORD key named AutoShareServer under h _ l _ m \ system \ currentcontrolset \ services \ lanmanserver \ parameters, and set the value to 0( 1 use, 0 prohibited).
For workstation: look for h _ l _ m \ system \ currentcontrolset \ services \ lanmanserver \ parameters.
Create a new DWORD key named AutoShareWks and set the value to 0 (used by 1 and prohibited by 0). It needs to be restarted after modification.
ADMIN$ is forbidden to enjoy * * * by default.
Under h _ l _ m \ system \ currentcontrolset \ services \ lanmanserver \ parameters, find a new REG_DWORD key named AutoShareWks and set its value to 0x0. It needs to be restarted after modification.
To restrict the enjoyment of IPC$ default * * *, find a new REG_DWORD named restrictanonymous under H _ L _ M \ System \ Current Control Set \ Control \ LSA.
Key and set its value to 0x0. It needs to be restarted after modification.
Note: 0x1-Anonymous users cannot list local users.
0x2-Anonymous user cannot connect to local IPC $ * * *
Note: 2 is not recommended, otherwise some services (such as SQL Server) may fail to start.
16. Unload useless dynamic links. Resource managers often leave useless dynamic links in memory. Look for H _ L _ M \ software.
\ Microsoft \ windows \ currentversion \ explorer \ creates a new DWORD subkey named AlwaysUnloadDLL.
Just set the value to 1 (set to 0, this function will be turned off).
17. Cancel file preview and caching. Under Windows XP, some files, such as. Avi files cannot be deleted. The system reports that they are in use.
It is caused by the file preview and cache function of the system. Turn off the preview and caching functions of avi files and delete the following registry keys:
h _ L _ M \ SOFTWARE \ Classes \ CLSID \ { 87 d62d 94-7 1 B3-4b 9a-9489-5 Fe 6850 DC 73 e }
Or close it by entering the cmd console command window and running: regsvr 32/u SHMEDIA.DLL (if you like.
Restore this function and run regsvr32 SHMEDIA.DLL)
18. Optimize the hard disk parameters, right-click my computer, select Properties, select the Device Manager tab under Hardware, then find your hard disk in the disk drive, check its properties, and select Write Cache Enabled in the Disk Properties tab;
Check the properties of the primary and secondary IDE channels in the IDE controller, and set the device type to auto-detect and the transfer mode to DMA (if available) in the advanced settings.
19. Turn off the Internet time synchronization function, click Start → Control Panel → Date, Time, Language and Region Options, and then click Date and Time → "Internet Time. Get rid of "automatic synchronization with Internet time server" directly! Start writing diary and mood from here …
