First, remove the unnecessary functions of XP:
1, reduce the waiting time of startup disk scanning, and start? Run, type: chkntfs /t:0
2. Delete the system backup file:
After all kinds of software and hardware are installed properly, XP rarely needs to update files. Start? Run, type: sfc.exe/Purge cache and press enter, which is almost 3xxMb.
Step 3 compress the 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. Cancel the registration of zipfldr.dll. Click start? Run, type: regsvr32/u zipfldr.dll. Then get into the car.
Second, remove the system garbage:
Now we will introduce the commands of two "Clean Disk" tools:
SAGESET
And SAGERUN
First, at "start" > enter and enter:
Cleaning Manager /sageset:99
set up
The special mode "Clean Disk" tool will run, and you will find many cleaning options. Select the files to be cleaned, which can generally be deleted. When you have made your selection, click OK. Then open start > run.
Input:
Cleanmgr /SAGERUN:99 execution
Third, slimming system: 1. Open? My computer? -? Tools? -? Folder options? -? Opinion? -What is it? Show all files and folders? Tick before the option-? Are you sure?
2. Delete the contents of the following folder:
All files under x: \ documents and settings \ user name \ cookies \ (keep index files)
All files under x: \ documents and settings \ user name \ local settings \ temp \ (user temporary files)
X: All files (page files) under \ Documents and Settings \ User Name \ Local Settings Temporary internet Files.
All files under x: \ documents and settings \ user name \ local settings \ history \ (history)
X: all files under \ documents and settings \ user name \ recent \ (shortcuts to recently browsed files)
X: all files under \ Windows \ temp \ (temporary files)
X:\WINDOWS\ServicePackFiles (backup files after upgrading sp 1 or sp2)
Compressed file under x:\WINDOWS\Driver Cache\i386 (backup file of driver)
All files under x: \ Windows \ Software Distribution \ Download.
3. If the system has been upgraded by windoes updade, please delete the following files:
Hidden files starting with $u ... in x:\windows\
4. Then defragment the disk, and please quit all running programs during defragmentation.
5. Open after defragmentation? Start? -? Program? -? Attachment? -? System tools? -? System restore? -? Create a restore point? (It is best to use the current date as the name of the restore point)
6. Open it? My computer? -Right-click the system disk-? Attribute? -? Disk cleaning? -? Other options? -Click the System Restore column? Clean up? -Choice? what's up -All right.
7. After all kinds of software and hardware are installed properly, XP rarely needs to update files. Delete system backup file: Start? Run? Sfc.exe/Purge cache nearly 3xxM. (This command is used to immediately clear the Windows File Protection file cache and release the space it occupies. )
8. Delete the dll file under \windows\system32\dllcache (minus 200? 300mb), this is a spare dll file, as long as you copy the installation file, you can do it completely.
9.XP will automatically back up the hardware driver, but it is generally unlikely to change the hardware after the hardware driver is installed correctly, so you can also consider deleting this backup. The file is located in the \windows\driver cache\i386 directory and named driver.cab You can delete it directly, usually the file is 74M.
10, delete unused input methods: For many netizens, not all input methods included in the Windows XPt system are suitable for their own use, such as IMJP8_ 1 Japanese input method and IMKR6_ 1 Korean input method. We can delete them if it is not necessary. Input method is located in \windows\ime\ folder, occupying 88M space.
1 1. After upgrading, I found that windows\ has many directories similar to $ ntuninstallq311889 $. Kill them all, 1x-3xM.
12. Besides, putting things in the \windows\help directory is also a kind of harm to me, hehe. . . Kill them all!
13. Turn off system restore: The system restore function takes up a lot of hard disk space for a long time. Therefore, manual setting is needed to reduce the hard disk occupation. Open the System Properties dialog box, select the System Restore option, and select the Turn off System Restore on all drives check box to turn off System Restore. You can also set to restore only the disk or partition where the system is located. Select the partition where the system is located, click the "Configure" button, and cancel the "Turn off system restore of this drive" option in the pop-up dialog box to set the disk space for system restore.
14, the hibernation function will take up a lot of hard disk space. If you use less, you might as well turn off * * *. To turn it off, open the Control Panel, double-click Power Options, select the Hibernation tab in the pop-up Power Options Properties dialog box, and uncheck the Enable Hibernation checkbox.
15, uninstall unused components: XP installs some system components for the operating system by default, and a large part of these components are impossible for you to use. You can uninstall them in Add/Remove Windows Components. However, some components in XP are hidden by default and cannot be found in Add/Remove Windows Components. At this time, you can open the file \windows\inf\sysoc.inf with Notepad, and replace all the "hidden" characters in the file with spaces with the find/replace function. In this way, the hidden properties of all components are removed. After saving, run the Add-Remove program, and you will see many options that you didn't see before. Delete those components you don't need (remember to save them as sysoc.inf instead of the default sysoc.txt), such as Internat messenger service, fax service, Windows messenger, code table, etc. , can release nearly 50MB of space.
16. Clear the temporary files of the system: 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 (Y: the partition where the system is located). Files in both locations can be deleted directly.
17. Erase temporary Internet files: A large number of temporary Internet files generated when surfing the Internet regularly will save a lot of hard disk space after being deleted. 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 Temporary Internet Files column, select the Delete All Offline Content check box in the pop-up Delete File dialog box, and click the OK button.
18. Clear the pre-read files: Although the pre-read setting of Windows XP can improve the system speed, after a period of use, the number of files in the pre-read folder will become quite large, resulting in a long 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.
19. Compress NTFS drives, files or folders: If your hard disk uses NTFS file system and space is really tight, you can also consider enabling NTFS compression. Right click. Drive to be compressed-Properties-General-Compress the disk to save disk space, then click OK, and select the required option in Confirm Property Change. This can save about 20% hard disk space. When compressing drive C, it is best to use safe mode for compression, which is more effective.
20. Close Dr. Watson: Close Dr. Watson, open the registry editor and find "HKEY _ Local _".
Machine \ software \ Microsoft \ Windows NT \ Current Version \ AE Debug "branch, 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, enter the drwtsn32 command in Start-> Run, or start-> Program-> Accessories-> System Tools-> System Information-> Tools-> Dr. Watson, and call up Dr. Watson in the system, and only keep the dump. If this has happened before, please look for the user.dmp file, which can save tens of MB of space after deletion.
2 1, close the remote desktop: "My Computer"-> "properties"->; "Remote" and "Allow users to connect to this computer remotely" in "Remote Desktop" are ticked.
22. Cancel XP's support for zip: Windows XP turns on support for ZIP files by default, 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 confirm that XP supports zip decompression, thus saving system resources.
23. Turn off the error report: When the application fails, a window will pop up to send the error report. In fact, such an error report is almost meaningless to ordinary users, so it is a wise choice to close it. In the System Properties dialog box, select the Advanced tab, 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 Group Policy: type gpedit.msc from Run, run Group Policy Editor, and expand Computer Configuration? Manage templates? System? Error reporting function ",double-click Error Reporting in the setting bar on the right, and select the Disable radio box in the pop-up Properties dialog box to disable Error Reporting.
24. Turn off unused devices: Windows XP always tries to install drivers for all devices of the computer and manage them as much as possible, which will not only slow down the system startup, but also occupy a lot of system resources. In view of this situation, in the device manager, you can disable uncommon devices, such as PCMCIA cards, modems, infrared devices, printer ports (LPT 1) or serial ports (COM 1). Double-click the device you want to disable and select 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.
25. Regularly clean the system restore point: turn on disk cleaning and select other options-> Clean up the system restore point, and then click Clean.
26, uninstall unnecessary programs, I don't need to say this.
27, other optimization:
A. Install the application software on other hard disks (don't install it under the system disk, which is also good for reinstalling the system);
B. Transfer all My Documents folders to other partitions: right-click the My Documents icon on the desktop and select Properties-> "moving";
Transfer all IE temporary folders to other partitions: open IE browser and select "Tools"->; "internet options"->; "general"->; "settings"->; "Move folder";
Transfer the virtual memory to another hard disk;
E points all pagefile.sys files to one place: control panel? System? Performance? Advanced? Virtual memory? Change, pay attention to the key point "Settings" will take effect;
Right-click the "My Computer" icon on the desktop and select "Properties"-> "advanced-performance settings"->; "Advanced-Virtual Memory", set to 330-720 (Genju Historical Records). And clean it regularly.
10. By default, xp pro reserves 20% of the network card bandwidth. If you use broadband, you may exceed this limit, so you need to remove this limit. The method is as follows: log in with administrator rights and start running? gpedit.msc？ , expand Computer Configuration, expand Management Templates, expand Network, expand qos Packet Scheduler, double-click Restrict Reserved Bandwidth in the right window, select the Enable option, change the value of Bandwidth Limit% to 0, and restart. This operation is not supported by Home Edition, and the restriction cannot be deleted.
13. Solve the problem that the nav of the machine with network card stops after winxp is started.
Start ~ Connect ~ Display all connections, press ~ Network Neighborhood ~ Right Click ~ Select Properties, under normal circumstances ~ Select Internet Protocol (tcp/ip)~ Press Properties, and use the following ip address ~ First ip address:192.168.0.1~ Second IP address. Or after the first boot, enter ipconfig in the dos command, and enter the ip address and subnet mask in the Ethernet adapter accordingly, and it will do ~ the boot will not stop in the future.
Fourth, the acceleration system:
1. Accelerate startup:
Although Windows XP is easy to use, it still takes a long time to start. Next, we will make it further shorten the startup time. Open the registry, find the subbranch of HKEY _ local _ machine \ system \ currentcontrolset \ control \ session manager \ memory management \ prefetch parameters in the registry editor, and change the key value of the right item to? 1? , (its default value is? 3? Is it much faster to restart the computer?
2. Accelerate shutdown:
Since the startup speed of Windows XP has increased, its shutdown speed will certainly be shortened. Open the registry editor, find the branch of HKEY _ Current _ User \ Control Panel \ Desktop subkey, and change the key value of HunaAppTimeout key to? 5000? , change the key value of the WaittoKillappTimeout key item to? 4000? . Next, find HKEY _ local _ machine \ system \ current control set \ control \ in the registry editor and change the key value of WaitToKillServiceTimeout to? 4000? It was later confirmed that restarting the system can also speed up the shutdown of Windows XP.
3. Quickly open the folder:
Are you online? Resource manager? If there are too many folders, just select the folder and press? *? Without a key, the computer will expand all subdirectories under this folder. For example, you chose? C disk? , and then press? *? Keys, can the computer put them? C disk? Open all the files under.
4. Restore the previous desktop settings at startup:
Someone is messing with my computer again, messing up my desktop settings. But it doesn't matter. Fortunately, I have my own secrets. Once I restart my computer, it will become my original settings. Come quickly if you want to learn! First, open the Registry Editor, find the subbranch of HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Policy \ Resource Manager, and set? NoSaveSettings？ Delete the key item or change its key value to? 0? , and then restart the system. Well, no matter how others change your desktop settings in the future, as long as you restart your computer, you will return to your previous settings.
5. Change the pop-up speed of the window:
You can change the pop-up effect of the window through some simple modifications, don't you want to try? First, open the registry editor, then find the subbranch of HKEY _ current _ user \ ControlPanel \ Desktop \ Window Metrics, 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 is prohibited, and then select? Log off? Command to activate the changes just made.
6. Set personalized startup information or warning information:
Your own computer, of course, has its own personality. Let's teach you a personalized Windows XP startup. Open the registry editor, find the subbranch of HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon, double-click the key value of LegalNoticeCaption, and open? Edit string? Dialog box, in? Numerical data? Enter the required information title in the text box under, such as? Hello, man! ? , and then click? Are you sure? , just restart the system. If you want to change the warning message, you can double-click the name of the LegalNoticeText key, and then click? Edit string? Enter a warning message to display in the window, and then click? Are you sure? Button, restart to see the modified effect.
7. Quickly check the driver component information:
Right click? My computer? In the pop-up menu, select? Management? , and then open it in turn? Mobile storage? Under it? Library? Right-click the drive you want to query and select? Attribute? , and then click? Equipment information? , you can easily see the drive information.
8. Don't waste your big memory. 1G memory usage guide.
[HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management], and modify the key values in the right pane (note that the memory is better than 5 12MB, Windows 2000/XP only).
Memory also needs to be optimized for maximum efficiency.
(1) "largesystem cache": opens a large memory space in memory for read-ahead operation of disk file system. When the data continuously requested by the program increases, Windows will automatically pre-read it through the system cache, so that the program can get the required data as quickly as possible. Because enabling this system buffer will take up more physical memory, the available physical memory that the program can use will be reduced. Set its value to 1. In this way, the system cache is increased from 4MB to 8MB.
(2) "second leveldatacache": the processing speed of CPU is much faster than the access speed of memory, and the memory is much faster than the hard disk. So there is a bottleneck effect between CPU and memory, and between memory and disk. The previous "LargeSystemCache" was designed to alleviate the bottleneck between memory and disk, and the CPU also set up a buffer mechanism L2 cache (secondary cache) to quickly get the processed data from memory. Adjusting this key value can make Windows better cooperate with CPU, and use this caching mechanism to obtain a higher data pre-reading hit rate. The recommended setting is 5 12.
Registry editor is a good tool to improve memory performance.
(3) DisablePagingexecutive: Change its value to 1 (hexadecimal), which will force all programs and data to run in physical memory instead of using virtual memory. Obviously, when there is enough physical memory to complete the required tasks, this will definitely greatly improve the system performance. Enabling it may be a disaster for users with only 64MB of memory? The system often made mistakes until it crashed.
