Seven, modify the registry
1. Accelerate startup and shutdown.
In [start]-> [run]-> type [registry]-> [HKEY current user]->; [Control Panel]-> [Desktop], change the numerical data of the string value [HungAppTimeout] to [200], and change the numerical data of the string value [WaitToKillAppTimeout] to 1000. In addition, in [HKEY _ Local _ Machine] → [System] →; [Current Control Set]-> [control], change the numerical data of the string value [HungAppTimeout] to [200], and change the numerical data of the string value [waittokilservicetimeout] to 1000.
2. Automatically close the stop response program.
In [start]-> [run]-> type [registry]-> [HKEY current user]->; [Control Panel]-> [Desktop], change the numeric data of the string value [AutoEndTasks] to 1, and then restart.
3. Clear the unused DLL files in the memory.
Type [regedit]-> [hkkey _ local _ machine] in [Start]-> [Run]-> [Software]-> [Microsoft]-> [Windows]-& gt； [CurrentVersion], add an item [AlwaysUnloadDLL] in [Explorer], and the default value is set to 1. Note: If the default value is set to [0], this function will be disabled.
4. Speed up the menu display.
In [start]-> [run]-> type [registry]-> [HKEY current user]->; [Control Panel]-> [Desktop], change the numeric data of the string value [MenuShowDelay] to [0]. If the menu display speed is too fast to adapt after adjustment, please change the value of [MenuShowDelay] to [200] and restart.
5, speed up the automatic refresh rate
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [system]-> [Current Control Set]-> [control]-> [Update], change the numerical data of Dword[UpdateMode] to [0], and then restart.
6, speed up the pre-reading ability, improve the boot speed.
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [system]-> [Current Control Set]-> [control]-> [Session Manager]-> [MemoryManagement], in the window to the right of [PrefetchParameters], change the numerical data of [enable prefetch] as follows. For example, if you use a CPU with PIII 800MHz or above, it is recommended to change the numerical data to 4 or 5, otherwise it is recommended to keep the numerical data as the default value, that is, 3.
7. Use the L2 cache of CPU to speed up the overall efficiency.
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [system]-> [Current Control Set]-> [control]-> [SessionManager], in the right window of [MemoryManagement], change the numerical data of [SecondLevelDataCache] to the same decimal value as the L2 cache of CPU: for example, P4 1.6G is 5 12Kb for an L2 cache, and the numerical data is changed to the decimal value of 5 12.
8. Run the defragmenter when you start the computer.
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [Software]-> [Microsoft]-> [Dfrg]-& gt； [BootOptimizeFunction], set the string value [Enable] to: y equals on, and n equals off.
9. Automatically close the stop response program when closing.
Type [Registry]-> [HKEY User]-> in [Start]-> [Run]; [.Default]-> [Control Panel], and then change the numerical data of [AutoEndTasks] to 1 in the window on the right side of [Desktop] to log off or restart.
10, speed up broadband access.
In [start]-> [run]-> in [HKEY local machine]-> [software]-> type [registry editing]->; [strategy]-> [Microsoft]-> [Windows], add a project named [Psched], and add a Dword value [nonbestforlimit] in the window to the right of [Psched]. The numerical data is 0.
1 1 to speed up the broadband network speed.
Open Registry Editor and locate.
HKEY _ local _ machine \ system \ currentcontrolset \ services \ tcpip \ parameters, right-click the parameter in the blank on the right, select the left "New" -> DWORD value edge, name it "DefaultTTL", right-click the mouse and select "Modify" to change the value to 80 (hexadecimal) or 128.
Change the value of GlobalMaxTcpWindowSize to 7FFF.
12, speed up online neighbors
Open the registry editor and find HKEY_LOCAL_MACHINE/sofew.
are/Microsoft/Windows/current version/explore/remote computer/namespace，delete。
Under it are {2227A280-3AEA-1069-A2DE08002B 30309D} (printer) and {D6277990-4C6A-1F8D87-00060F5 BF} (plan)
After optimization, the phenomenon you mentioned should not appear. Good luck.
