XP Registry Optimization and Drive Optimization

More and more users are using Windows XP because Windows XP is more versatile and easy to use. But if your hardware is not advanced enough, then her speed can not be complimented. Of course, it is not only the upgrade hardware to meet the "greedy" needs of XP? We can improve the speed of Windows XP through various software!

Registry optimization scheme

1, enable CPU L2 Cahce

To the registry HKCU_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management, create a new DWord value:

SecondLevelDataCache, modify this value to your CPU's L2 cache. Size, when using the decimal value. You can change the CPU's Level 2 cache to 256KB by modifying the DWord value "SecondLevelDataCache" and restart the computer.

2. Modifying disk cache acceleration XP

Disk caching plays a crucial role in XP operation, but the default I/O page file is conservative. Therefore, it is better to use different disk caches for different memories.

To the registry HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\IoPageLockLimit, modify its hexadecimal value according to your memory (64M: 1000; 128M: 4000; 256M: 10000; 512M Or greater: 40000).

3. Remove the menu delay

Remove the delay when sliding out the menu, which can speed up XP to a certain extent. The key value to be modified is in HKEY_CURRENT_USERControl PanelDesktop. The specific key to be modified is "MenuShowDelay", just change the value to 0. Of course, the changes will not take effect until you restart your computer.

4, specify the process order

simultaneously press the Control+Alt+Delete three keys, then click the "Processes" tab, you can see a dialog box, where you can See all the processes that are currently running. If you want to allocate more process time for a program, such as 3D Studio Max, just right click on the process, then move the mouse pointer down to "Set Priority" (Set Priority), then select the program you want. Which priority is in it. When I receive the email, I will set 3DMAX as "standard", but when I leave the computer, I will raise its priority to the highest "real time", so that the computer can focus on 3D actions more quickly and more quickly. .

5, cancel the reserved bandwidth in Windows XP Professional

Because the professional version needs on the network, it is set 20% of the default reserved bandwidth, in fact, for individual users, these reserved bandwidth is useless, you can use the Group Policy Editor to cancel the reserved bandwidth.

Enter gpedit.msc in Start → Run to open the Group Policy Editor. Find "Computer Configuration" → "Administrative Templates" → "Network" → "QoS Packet Scheduler", select "Limitable Retainable Bandwidth" on the right, select "Properties" to open the picture, select "Disable". This is very beneficial for users who use Modem - freeing up the reserved bandwidth to speed up the browsing and downloading of the Internet!

6, Windows XP does not check the scheduled tasks

Normally, When Windows XP is connected to another computer, it will check all the scheduled tasks on the other machine. This process will let you wait for 30 seconds, which is really annoying. Let's disable this process by finding
HKEY_LOCAL_MacHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\RemoteComputer\\NameSpace in the registry. Inside, there should be a {D6277990-4C6A-11CF-8D87-00AA0060F5BF} button. Just delete it, restart the computer, Windows will not check the scheduled tasks, the speed is significantly improved!

Driver optimization scheme

1, if it is Intel 8XX chipset If you must install Intel Application Accelerator, the system optimization is obvious after installation. This thing can be downloaded from the official Intel website.

2. If it is a motherboard of a non-Intel chipset, it is essential to install the corresponding patch, such as VIA's 4in1 program.

3. Try to use WHL-certified drivers. This driver is certified by Microsoft Hardware Labs and has great advantages in terms of stability and compatibility.

Other optimization schemes

1. Startup acceleration

Although the startup speed of Windows XP is much higher than that of Windows 98, there is still room for acceleration. Go to the Microsoft site to download the Bootvis.exe file, start it, select Trace→Optimize System in the menu, then the system will prompt whether to restart, select start, restart after login, do not move anything, after a period of time will automatically pop up a dialogue The box, the dialog box is written with system analysis and other prompt information, you do not do anything, until the prompt analysis is completed, so the startup speed is obviously improved.

2, remove unnecessary services

After Windows XP starts, many services are started, some of which are useless for many users and take up Memory, let's take a look at which services need to be turned off.

Click "Start" → "Run" and enter the command "services.msc" to open the "Services" dialog box. (Note: You must be logged in as an administrator or a member of the Administrators group to complete the process. If the computer Network connection settings can also prevent you from completing this step.)

Clipbook Server: This service allows other users on your network to see your folder. Here I would strongly recommend that you change it to manual startup and then use other programs to post information on your network.

Messenger: Sends and receives information on the network. If you turn off Alerter, you can safely turn it into manual startup.

Printer Spooler: If you don't have a printer configured, it is recommended to start it manually or simply turn it off.

Error Reporting Service: Error reports are provided when services and applications run in a non-standard environment. It is recommended to start manually.

Fast User Switching Compatibility: It is recommended to start manually.

Automatic Updates: This feature has already been mentioned before, you can change it manually here.

Net Logon: Handles network security features like registration information. You can change it to manual startup.

Network DDE and Network DDE DSDM (Dynamic Data Exchange): Unless you are ready to share your Office online, you should change it to manual startup. Note: This is different from using Office in the usual business settings (you will know if you need DDE).

NT LM Security Support: Provides security in web applications. It is recommended to start manually.

Remote Desktop Help Session Manager: It is recommended to start manually.

Remote Registry: Enables remote users to modify registry settings on this computer. It is recommended to start manually.

Task Scheduler: Enables users to configure and schedule automated tasks on this computer. It schedules defragmentation every week. Unless you are too lazy, don't even want to open it on your computer. It is recommended to start it manually.

Uninterruptible Power Supply: Used to manage your UPS. If you don't have a UPS, change it to manual start or simply turn it off.

Windows Image Acquisition (WIA): Provides image capture for scanners and cameras. If you don't have these devices, it is recommended to start it manually or simply turn it off.

3. Using a fixed virtual cache

It is recommended to set both the maximum and minimum values ​​to 382M regardless of the size of your physical memory.

4, to ensure that memory usage is prioritized for the program, CPU plan is preferred for the program

first open the "system" property, then select the "Advanced" tab, click in the "Performance" column "Settings" button, open the "Performance" options dialog box, then open the "Advanced" tab, select "Programs" in the "Processor Plan" column, select "Programs" in the "Memory Usage" column, and then click "OK" to exit.

5, clear pre-read files

When XP is used for a period of time, the files in the pre-reading folder will become very large, there will be dead chain files, which will slow down the system. time. It is recommended that these files be deleted periodically (c:\\Windows\\prefetch).

6, reduce the disk scan waiting time

Under DOS, type "chkntfs/t:0", where "0" means the waiting time is 0 seconds.

7. Close the disk index

XP records all the files for quick search. If you don't find the file often, you can close it. The specific method is: open my computer, right click on the drive, select "Properties", cancel "Use index to quickly find files".
