Nine tips to improve XP running speed by 100%

In the process of using XP, the system will run slowly over time. Some friends may think of reinstalling the system, but after reinstalling, so many applications need to be re-installed. How can we speed up XP without installing the system? As long as you perform the following nine operations, I believe your XP will run at high speed again.

1. When the host is shut down in Windows XP, the system will send a message to the running program and remote server, telling them that the system is shutting down and the system will not shut down until a response is received. To speed up the startup, You can first set Automatic task termination. First, find hkey_current_usercontrol paneldesktop and set the autoendtasks key value to 1. Then there is a "hungapptimeout" under the branch ", change the value to "4000 (or less). The default value is 50000. Then, locate hkey_local_machinesystemcurrentcontrolsetcontrol and set waittokillservicetimeout to" 4000 ". The shutdown speed is much faster.

2. Windows XP, which increases the bandwidth speed of the Professional Edition, retains 20% of the bandwidth by default. In fact, this has no effect for our individual users. In particular, it is better to make full use of it. In Start> Run, enter gpedit. MSC to open the Group Policy Editor. Find "Computer Configuration> management template> network> QoS packet scheduler", select "restricted and retained bandwidth" on the right, and select "properties" to open the "restricted and retained bandwidth attributes" dialog box, select "enable" and change the original "20" to "0" to release the reserved bandwidth.

3. Optimize the network neighbor Windows XP when the network neighbor is in use, the system will search for its own shared directory and can be used as a network shared printer, as well as scheduled tasks and network-related scheduled tasks, and then display, the speed will obviously be much slower. If these functions are not very useful to us, we can delete them. In the Registry Editor find versionpoliceremotecomputernamespace, delete the (printer) and {D6277990-4C6A-11CF8D87-00aa0060f5bf} (scheduled task) under it, restart the computer, and access the network neighborhood again, you will find much faster.

4. To speed up Windows XP startup. You can modify the Registry to achieve the goal. In the Registry Editor, find hkey_local_machinesystemcurrentcontrolsetcontrolsession managermemory managementprefetchparameters, find the enableprefetcher primary key on the right, and change the default value 3 to 1, reducing;

5. automatically shut down the stop Response Program. Sometimes, XP will prompt you to stop responding to a specific program. It is annoying. You can modify the Registry to disable it by yourself, in hkey_current_usercontrol paneldesktop, change the value of the character key value autoendtasks to 1 and log off or start it again.

6. Speed up the display of menus. To speed up the display of menus, follow these steps: you can find the "menushowdelay" primary key under hkey_current_usercontrol paneldesktop, change its value to "0" to accelerate the display speed of the menu.

7. Clear the hkkey_local_machinesoftwaremicrosoftwindowscurrentversion of the non-used DLL file in the memory in the registry. add an item alwaysunloaddll in Explorer. The default value is 1. Note: If the default value is 0, this function is disabled.

8. Speeding up the pre-read capability and improving the boot speed Windows XP pre-read settings can improve the system speed and boot speed. Follow these steps to make better use of the CPU efficiency: hkey_local_machinesystemcurrentcontrolsetcontrolsessionmanagermemorymanagement]. In the right window of prefetchparameters, change the value of enableprefetcher as follows, if you use a piII 800 MHz CPU or above, we recommend that you change the value data to 4 or 5. Otherwise, we recommend that you retain the value data as the default value of 3.

9. Reduce the number of loaded projects at startup. Many applications are automatically added to the system startup group during installation. The system runs automatically every time it is started, which not only prolongs the startup time, after the startup is complete, the system resources have been consumed! Start the "System Configuration Utility", list the projects and sources loaded during system startup in the "Start" item, and carefully check whether you need it to be automatically loaded, otherwise, clear the check box before the project. The fewer projects to load, the faster the startup speed. This item must be restarted to take effect.
