XP registry and driver optimization

1. Enable CPU L2 Cahce

Go to the Registry HKCU_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management and create a Dword Value:

SecondLevelDataCache: modify this value to the second-level cache size of your CPU, and use a 10-digit value when entering the value. You can modify the Dword Value "SecondLevelDataCache" to change the CPU Level 2 cache to kb, and then restart the computer.

2. Modify disk cache to accelerate XP

Disk cache plays a vital role in XP operations, but the default I/O page files are relatively conservative. Therefore, it is better to use different disk caches for different memories.

Go to the Registry HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ IoPageLockLimit and modify the hexadecimal value (64 M: 1000; 128 M: 4000; 256 M: 10000; 40000 M or larger ).

3. Remove menu Delay

Remove the delay when sliding out of the menu to speed up XP to a certain extent. The key value to be modified is HKEY_CURRENT_USERControl PanelDesktop. The key to be modified is "MenuShowDelay". You only need to change the value to 0. Of course, the change takes effect only after the computer is restarted.

4. Specify the Process Order

At the same time, press the Control + Alt + Delete keys and click the "Processes" tab. A dialog box is displayed, showing all Processes currently running. If you want to allocate more process time to a program, such as 3D Studio Max, right-click the process and move the mouse pointer down to Set Priority> (Set Priority )", then select the priority of the program you want. When I receive an email, I set 3DMAX to "standard", but when I leave the computer, I will upgrade it to the highest "real-time" priority ", in this way, computers can focus more on processing 3D actions more quickly.

5. Cancel the reserved bandwidth in Windows XP Professional Edition.

Because the Professional Edition is needed on the network, the default reserved bandwidth of 20% is set. In fact, for individual users, the reserved bandwidth is useless, you can use the Group Policy Editor to cancel Bandwidth Reservation.

In start → run, enter gpedit. msc to open the Group Policy Editor. Find "Computer Configuration"> "management template"> "network"> "QoS packet scheduler", and select "restrict retained bandwidth" on the right ", select "attribute" to open the image and select "Disable. This is very good for Modem users-releasing the reserved bandwidth can speed up online browsing and downloading!

6. Windows XP does not check the scheduled task

Generally, when Windows XP is connected to another computer, it will check all the scheduled tasks on the other computer. This process will make you wait for 30 seconds, which is so annoying. Let's disable this process by finding it in the registry.

HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ RemoteComputer \ NameSpace. There should be a key. You just need to delete it. After restarting the computer, Windows will no longer check the scheduled task, and the speed will be significantly improved!

Driver optimization solution:

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

2. If the motherboard is not an Intel chipset, installing corresponding patches is essential, such as the VIA 4in1 program.

3. Try to use the driver that has passed the WHL authentication. This kind of driver has been certified by Microsoft hardware lab and has great advantages in stability and compatibility.
