Editor to share with you what are the registry optimization skills commonly used in the win7 system. I hope you will gain something after reading this article. Let's discuss it together.

Open the Registry Editor:

1, hold down the keyboard "Win+R" shortcut key combination or click the start menu, select run, and open the "run" command dialog window.

2. Then type Regedit to open the registry editor

Back up the registry:

Before optimizing the registry, in order to prevent accidents during the registry optimization process, we'd better back up the registry first.

The method is: in the Registry Editor window-[File]-[Export]-Select the export part or all-enter the file name-save. Once you modify the error, you can use the "import" method to recover. If there is a problem with the modification, you can restart the computer, press the F8 key continuously, and select the last correct configuration from the start menu.

Ten commonly used registry optimization methods

1. Speed up the startup and shutdown

In [start]-- [run]-- type [Regedit]-- [HKEY_CURRENT_USER]-- [Control Panel]-- [Desktop], change the numeric data of the string value [HungAppTimeout] to [200] and the numeric data of the string value [WaitToKillAppTimeout] to 1000. In addition, in [HKEY_LOCAL_MACHINE]-- [System]-- [CurrentControlSet]-- [Control], change the numerical data of the string value [HungAppTimeout] to [200], and change the numerical data of the string value [WaitToKillServiceTimeout] by 1000.

2. Automatically close the stop response program

In [start]-- [run]-- type [Regedit]-- [HKEY_CURRENT_USER]-- [Control Panel]-- [Desktop], change the numeric data of the string value [AutoEndTasks] to 1, and restart it.

3. Clear DLL files that are not used in memory

Type [Regedit]-- [HKKEY_LOCAL_MACHINE]-- [SOFTWARE]-- [Microsoft]-- [Windows]-- [CurrentVersion] in [start]-- [run]-- type [Regedit]-- [HKKEY_LOCAL_MACHINE]-- [SOFTWARE]-- [start]-- [run]-- type [start]-- [run]-- [run]-- type [start]-- [run

Note: if the default value is set to [0], this feature is disabled.

4. Speed up the display of menu

Type [Regedit]-- [HKEY_CURRENT_USER]-- [Control Panel]-- [Desktop] in [start]-- [run]-- change the numerical data of the string value [MenuShowDelay] to [0]. If you feel that the menu is displayed too fast to adapt, you can change the numerical data of [MenuShowDelay] to [200] and restart.

5. Speed up the automatic refresh rate

Type [Regedit]-- [HKEY_LOCAL_MACHINE]-- [System]-- [CurrentControlSet]-[Control]-- [Update] in [start]-- [run]-- type [System]-- [CurrentControlSet]-- [Control]-- [Update], change the numerical data of Dword [run] to [0], and restart.

6. Speed up the pre-reading ability and improve the boot speed

Type [Regedit]-- [HKEY_LOCAL_MACHINE]-- [SYSTEM]-- [CurrentControlSet]-- [Control]-- [SessionManager]-[MemoryManagement] in [start]-- [run]-- type [Regedit]-- [run]-- type [start]-- [HKEY_LOCAL_MACHINE]-- [SYSTEM]-- [CurrentControlSet]-- [Control]-- [SessionManager]-[MemoryManagement] in the right window of [start], change the numerical data of [EnablePrefetcher] to 4 or 5, otherwise it is recommended to keep the numerical data as the default value

7. Use CPU's L2 Cache to accelerate overall performance

In [start]-- [run]-- type [Regedit]-- [HKEY_LOCAL_MACHINE]-- [SYSTEM]-- [CurrentControlSet]-- [Control]-- [SessionManager], in the right window of [MemoryManagement], change the numerical data of [SecondLevelDataCache] to the same decimal value as CPU L2 Cache: for example: L2 Cache of P41.6GA is 512Kb, numerical data is changed to decimal value 512.

8. Automatically close the stop response program when shutting down the computer

In [start]-- [run]-- type [Regedit]-- [HKEY_USERS]-- [.DEFAULT]-- [Control Panel], and then change the numerical data of [AutoEndTasks] to 1 in the right window of [Desktop], log out or restart.

9. Speed up broadband access

In [start]-- [run]-- Type [regedit]-- in [HKEY_LOCAL_MACHINE]-[SOFTWARE]-- [Policies]-- [Microsoft]-- [Windows], add an item named [Psched], and add a Dword value [NonBestEffortLimit] to the right window of [Psched] to 0.

10. Speed up the broadband network

Open the registry editor, find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpip parameters, right-click parameters in the right space, select the left "New"-DWORD value edge, name it "DefaultTTL", right-click to select "modify", change the value to 80 (hexadecimal), or 128 (decimal), change the value of GlobalMaxTcpWindowSize to 7FFF.
