How to optimize the WinXP system strategy

How can I make my WinXP system application safe to start faster and work more stable, then how can I do it? The following system home will give you a simple sharing, how to optimize WinXP system:

First, how to speed up the shutdown speed

Like the startup, Windows XP shutdown speed is the same slow, to To speed up the shutdown, first we need to open WinXP's auto-end task function (AutoEndTasks) through the registry. The specific steps are: Find HKEY_CURRENT_USERControl PanelDesktop, set the AutoEndTasks key to 1.

Then modify “HungAppTimeout” is "4000 (or less)" (default is 50000), the key value is also in the HKEY_CURRENT_USERControl PanelDesktop directory; the last step is to find HKEY_LOCAL_MACHINESystemCurrentControlSetControl, the same WaitToKillServiceTimeout is set to “4000”; The shutdown speed after this setting is obviously faster,

Second, completely turn off Windows XP file protection function

Find HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon from the registry, modify “SFCDisable” The key value is "FFFFFF9D”, if you need to re-enable this feature, reset it to “0”

Third, start the hard disk /optical drive DMA mode

Open system properties -> Hardware -> Device Manager -> IDE ATA /ATAPI controllers, select “Primary IDE Channel” or “Secondary IDE Channel”, check if the DMA mode is enabled. Generally speaking, if the device supports it, the system will automatically turn on the DMA function; in addition, the transmission mode currently used by the drive can also be seen here.

Fourth, disable Dr. Watson debugger

Enter "ldwtsn32" in the run, and then dump all thread contexts except "Dump All Thread Contexts" All are removed, otherwise the hard disk will ring for a long time and there will be a lot of hard disk space.

V. Shorter startup time

It is recommended that you use the Bootvis software released by Microsoft, which can automatically optimize the system to shorten the time it takes to start. Select “Trace” Optimize System” Then restart it; you can also reduce the startup time by reducing the startup time of the program loaded by Windows XP's built-in MsConfig setup program. Enter the startup only when running “msconfig” and then through “Startup”. The relevant settings are fine.

1, Bootvis

2, msconfig

6. Set the processor's L2 cache capacity

Windows XP cannot automatically detect the processor's L2 cache. Capacity, we need to manually set it in the registry, first open the registry (run "Enter" Regedit", and then open:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management

Select “SecondLevelDataCache”, According to the processor settings you use, for example, PIII Coppermine/P4 Willamette is “
