1, accelerate online neighbors
Open the Registry Editor and find HKEY _ Local _ Machine/Software/Microsoft/Windows/Current Version/Discovery/Remote Computer/Namespace. Delete {2227A280-3AEA-1069-A2DE08002B 30309D} (printer) and {D6277990-4C6A-1F8D87-00060F5 BF} (.
2, reduce the time to start the scroll bar.
Every time you start Windows XP, you have to walk the blue scroll bar several times. In fact, we can also reduce its scrolling time here to speed up the startup. Open the registry editor, find HKEY _ local _ machinesystem \ currentcontrolset \ control \ sessionmanager \ memory management prefetch parameters, find the EnablePrefetcher primary key on the right, and change its default value of 3 to 1, so that the scrolling time of the scroll bar will be reduced.
3, speed up the boot speed
When shutting down in XP, the system will send a message to the running programs and remote servers, telling them that they should shut down the system and wait for the response before the system starts to shut down. To speed up the startup, you can set the task to end automatically first. First, find HKEY _ Current _ User \ Control Panel \ Desktop, and set the key value of AutoEndTasks to 1. Then there is a "HungAppTimeout" under this branch, and its value is changed to "4000 (or below), and the default is 50000; Finally, find HKEY _ local _ machine \ system \ current control setting control \, and also set WaitToKillServiceTimeout to "4000"; Setting the shutdown speed in this way is obviously much faster.
4. Eliminate menu delays
In order to achieve visual realism, the menu in Windows XP will slide out when it is opened, but it will also slow down the opening speed. We can find the "MenuShowDelay" primary key under HKEY _ Current _ User \ Control Panel \ Desktop and change its value to "0" to remove the menu delay effect.
5, improve the broadband speed
Windows XP Professional Edition reserves 20% bandwidth by default, which has no effect on our individual users. It is better to make full use of it than to leave it idle.
Enter gpedit.msc in Start → Run to open the Group Policy Editor. Find "Computer Configuration → Management Template → Network →QoS Packet Scheduler", select "Restrict Reserved Bandwidth" on the right, select "Properties" to open the dialog box of Restrict Reserved Bandwidth, and select "Disable". This releases the reserved bandwidth, which is very useful for friends who surf the Internet.
Skills of XP to improve performance
First, cancel the decompression function.
Windows XP can extract Zip files by itself, but do you prefer Winzip and WinRAR? Then cancel the default decompression function of Windows XP! Press Start → Run, enter "REGSVR32/U zipfldr.dll" and confirm. Next, a window will pop up and press OK, so the decompression function of Windows XP will be cancelled.
Second, remove the waiting time for disk scanning.
When Windows XP shuts down abnormally, it takes 10 seconds to start disk scanning after restarting. If you think 10 second is too long, let it be 0 second! Press Start → All Programs → Accessories → Command Prompt and type CHKNTFS /T? 0 "and then press enter, so you don't have to wait that long 10 seconds next time.
Third, speed up the download.
By default, Windows XP reserves 20% of the connection bandwidth for programs that support QoS, but most programs do not support QoS services, and not all devices provide QoS packet flow management. So releasing this reserved 20% bandwidth can improve the download speed a lot. Press Start → Run, enter gpedit.msc, and the group policy window will pop up. On the left side of the window, click Computer Configuration → Management Module → Network →“QoS Packet Scheduler, right-click to limit the reserved bandwidth, select Properties, and select Settings in the pop-up window.
Fourth, release the space occupied by system backup.
Windows XP will automatically back up some important system files after installation. If you want to make room for these files, well, press Start → Run, enter sfc /purgecache, and then confirm. Wait a minute, you will find more hard disk space!
5. Delete the pre-read file to improve the system performance.
Windows XP has a folder dedicated to storing the pre-read files of the installed software for pre-reading to speed up the running of the software, but Windows XP will not automatically delete the pre-read files of the uninstalled software, so it must be deleted manually. Enter "x? Windows prefetch "(X stands for the partition where Windows XP is located) folder, and delete all files except" Layout.ini ".
All the documents.
Six, all-round understanding of your computer
Want to fully understand the software and hardware information and usage of your computer? Windows XP already has a powerful system information collector. Press Start → Help and Support to open the Help and Support Center window. Select "Use tools to view your computer information and analyze problems" on the right, and then select "My computer information" in the list on the left. Well, you can choose the information you want to know on the right (much more intuitive than the system information obtained by Msinfo32.exe! .
Seven, instantly lock the computer
I suddenly have something to leave for a while, but I don't want to turn off my phone. In order to prevent others from touching your computer, you just need to press the Windows logo key +L to lock the computer quickly. Unless you know the password, no one can touch it!
Eight, modify the secondary cache of cpu
In general, xp will automatically identify the second-level cache of cpu. But sometimes xp won't do this, so manual optimization is needed to improve the performance of cpu.
1. Run "regedit";
2. Go to [HKEY _ Local _ Machine \ System \ Current Control Set \ Control \ Session Manager \ Memory.
management \ SecondLevelDataCache]"；
3. Modify his decimal system: 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;
4. restart.
Nine, modify the disk cache to accelerate xp
Disk cache plays an important role in xp operation, but the default I/O page file is conservative. Therefore, it is a good practice to use different disk caches for different memories.
1. Run "regedit";
2. Go to [HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ iopagelocklimit];
3. Modify its hexadecimal value according to your memory: 64m:1000; 128m:4000； 256m: 10000； 5 12M or above: 40000
restart
Ten, look at the settings in advance, improve the speed.
Xp uses the new technology of pre-reading settings to improve the system speed. If you have more than PIII 80012m of memory, it is recommended to modify it:
1. Run Electronic Edit.
2. Go to [HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ prefetch parameters \ enable prefetcher];
3. 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.
Use).
4. restart. This can reduce the startup time.
XI。 Clear pre-read file
After xp is used for a period of time, the files in the pre-read folder will become very large, and there will be dead-chain files in it, which will slow down the system time. It is recommended to delete these files regularly. (c:\windows\prefetch)
12. Reduce the waiting time of disk scanning
Under dos, type "chkntfs/t:0" 0" 0: to indicate that the waiting time is 0 seconds.
Thirteen, close the disk index
Xp records all files for quick search. If you don't look for files often, you can close them.
Turn on my computer.
2. Right-click the drive and select Properties.
3. Cancel "Use index to find files quickly".
Fourteen, fix the bug of mouse acceleration
1. When playing quake3 and cs in xp, there is something wrong with mouse acceleration, and the marksmanship becomes inaccurate. The adjustment named "yinxs" can correct this error.
Run the Registry
3. Go to [HKEY _ Current _ User \ Control Panel \ Mouse] "SmoothmouseXCurve" = hex: 00, 00, 00, 00, 00, A0, 00, 00, 00, 00, 00.
，\ 0 1，00，00，00，00，00，80，02，00，00，00，00，00，05，00，00，00，00，00，00，00，00，00，66，6，02，
00，00，00，00，00，cd，4c，05，00，00，00，99，0a，00，00，00，00，00，38，33， 15，00，00，00，00，00，00
restart
Fifteen, optimize the ntfs file system
Needless to say, ntfs has advantages, but it also has disadvantages. Canceling the update of the last disk access will slow down the speed of large-capacity partition.
Run "regedit" in HKEY _ local _ machine \ system \ currentcontolset \ control \ file system) and add DWORD with the value of 1.
