2, improve the broadband speed

The professional version of Windows XP retains 20% of the bandwidth by default, which does not really work for our individual users. In particular, it is better to make full use of it than to be idle.

Enter gpedit.msc in Start → Run to open the Group Policy Editor. Find "Computer configuration → admin templates → network →qos Packet Scheduler", select restrict reserved bandwidth on the right, select Properties to open the limit to reserve the Bandwidth Properties dialog box, select Enable, and change the original "20" to "0", freeing up the reserved bandwidth.

3, optimize the Network Neighborhood

Windows XP Network Places use the system to search for their own shared directories and printers that can be shared as a network, as well as scheduled tasks that are related to the network in a task, and then appear so that the speed is significantly slower. These features are not much use to us, you can delete them. Locate the Hkey_local_machinesofewaremicrosoftwindowscurrent Versionexploreremotecomputernamespace in Registry Editor, remove the (printer) and { D6277990-4C6A-11CF8D87-00AA0060F5BF} (scheduled Task), restart your computer, visit your network Neighborhood again, you will find a lot faster.

4, speed up the start

You can do this by modifying the registry, and in Registry Editor, find Hkey_local_machinesystemcurrentcontrolsetcontrolsession managermemory Managementprefetchparameters, find the Enableprefetcher primary key on the right, change its default value of 3 to 1, so that the scroll bar scrolling time will be reduced;

5, automatic shutdown Stop responder Program

In some cases, XP will prompt you a certain program to stop responding, very annoying, by modifying the registry we can let it shut itself, in Hkey_current_usercontrol paneldesktop the word Fu Jian value is autoendtasks numeric data to 1, Log off or start again.

7. Erase DLL files that are not in use in memory

In the registry hkkey_local_machinesoftwaremicrosoftwindowscurrentversion, add an item Alwaysunloaddll to the Explorer, and the default value is 1. Note: If the default value is set to 0, this feature is deactivated.

8, speed up reading ability to improve boot speed

Windows XP pre-read setting increases system speed and speeds up the boot speed. The following methods can be used to further optimize the efficiency of the CPU: Hkey_local_machinesystemcurrentcontrolsetcontrolsessionmanagermemorymanagement], In the Prefetchparameters right window, the Enableprefetcher value data is changed as follows, such as the recommendation to use PIII 800MHz CPUs to change the value data to 4 or 5, otherwise it is recommended that the value data be retained as the default value of 3.

9. Reduce Startup Load Items

Many applications are automatically added to the system startup group at the time of installation, and each boot system is automated, which not only prolongs startup times, but also consumes system resources after the startup is complete!

Start the System Configuration Utility, and in the startup item, list the items and sources that are loaded when the system starts, and carefully see if you want it to load automatically, otherwise clear the current check box of the item, the fewer items loaded, the faster the startup speed. This item requires a reboot before it can take effect.
