I'll teach you how to learn. System Performance Optimization Registry Modification Instance (3) _ Registry

Friends, have you ever found your Windows XP system fast enough? Is it that although the hardware configuration is already high, some places seem to be "unavoidable" to wait? In fact, there are many system settings to wait for a longer timeout condition, resulting in you can only "wait" with it, as long as in the registry of these places wait for the delay to change the smaller, especially when the switch machine, the system speed will be significantly accelerated.

Reduce the boot scrollbar scrolling time:

Every time you start Windows XP, the blue scroll bar has to go many times, but here we can also reduce its scrolling time to speed up the start. Open Registry Editor to find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\prefetchparameters, find the Enableprefetcher primary key on the right, change its default value of 3 to 1, so that the scroll bar scrolling time is reduced.

Speed down shutdown:

When shutting down in XP, the system sends a message to the running program and remote server, telling them that the system is shutting down and waiting for a response before the system starts shutting down. Speed up the boot, you can set the automatic End task, first find HKEY_CURRENT_USER\Control Panel\Desktop, the Autoendtasks key value set to 1, Change the waittokillapptimeout to 1000 (wait only one second), and then there is a "hungapptimeout" under the branch, changing its value to "200 (for 0.5 seconds)", default 50000; Find Hkey_local_ Machine\system\currentcontrolset\control\, the WaitToKillServiceTimeout is also set to "1000 (for one second)", and by this setting the shutdown speed is significantly faster.

Remove Menu delay:

When we first introduced the registry appearance changes, have written about the removal of the pop-up menu of the annoying problem, which for some users are satisfied, but for some other users, they may prefer to quickly pop-up menus to reflect the speed of the system. Also, in order to achieve visual realism, the menu in Windows XP does increase the effect of slipping when it is turned on, which also slows down the opening speed. We can find the "Menushowdelay" primary key under HKEY_CURRENT_USER\Control Panel\Desktop, change its value to "0" to remove the menu delay effect.

Speed Up your Network Neighborhood

Access to your network Places in Windows XP is rather annoying, and the system searches for its own shared directories, printers that can be shared as a network, and scheduled tasks that are related to the network in a scheduled task before being displayed, apparently at a slower rate than in Windows 9x. In fact, these features we do not use, rather than do not have to delete them, so the speed will be significantly faster. Open hkey_local_machine\sofeware\microsoft\windows\
Currentversion\explore\remotecomputer\namespace, remove the (printer) and {D6277990-4C6A-11CF8D87-00AA0060F5BF} (Scheduled Tasks), restart the computer, Visit your online neighbors again and you'll find it a lot quicker.

Shielding ActiveX Plug-ins:

Although the ActiveX plugin makes some pages more exciting and beautiful, but also bring us a lot of inconvenience, such as constantly prompt pop-up certificate-related message boxes, and so on, if you agree to install the relevant certificates, but also on the default home page and other effects, some users do not like, to a large extent, affecting the speed of browsing the web. In fact, as long as in the registry slightly modified, you can plug the ActiveX Plug-ins, to achieve the blockade of 3721/cnnic/baidu, and the basic will not have an impact on the browsing of the Web page, so that both protect the security of IE, and speed up the pace of browsing the Web page. This can be considered the best way.

Open the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility subkey and locate the

{B83FC273-3522-4CC6-92EC-75CC86678DA4} (corresponds to 3721)
{9a578c98-3c2f-4630-890b-fc04196ef420} (corresponding cnnic)
{cf051549-ede1-40f5-b440-bcd646cf2c25} (corresponding Popo)
{4edbbaea-f509-49f6-94d1-ecec4be5b686} (corresponding to Chinese mail)

Change the value of the double byte key value item "Compatibility Flags" in their right window to 0x00000400.
