How Win7 speeds up network connectivity and system response speed

When the computer was just bought, it was running smoothly. The speed was quite fast, but it was not so fast after a long time. No matter how fast the network connection speed or system response speed was, how to speed up Win7 What about network connectivity and system response speed?

First, registry optimization network acceleration

1, to accelerate the speed of broadband access

[Start] - [Run] - type [regedit] --In [HKEY_LOCAL_MACHINE]--[SOFTWARE]--[Policies]--[Microsoft] --[Windows], add an item named [Psched] and add a Dword value in the [Ssched] right window [NonBestEffortLimit] The numerical data is 0.

2, speed up the broadband network speed

Open the registry editor, find HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip \\ parameters, right click on the parameters in the right margin, select left “ ”—DWORD value side, name it "DefaultTTL", right click the mouse to select "ld"; modify & rdquo;, the value is changed to 80 (hexadecimal), or 128 (decimal), the value of GlobalMaxTcpWindowSize Change to 7FFF.

3, speed up the network neighborhood

Open the registry editor, find HKEY_LOCAL_MACHINE/sofeware/Microsoft/Windows/Current Version/Explore/RemoteComputer/NameSpace, delete the {2227A280-3AEA- 1069-A2DE08002B30309D} (printer) and {D6277990-4C6A-11CF8D87- 00AA0060F5BF} (planned tasks).

Second, registry optimization software response

1, the program automatically shut down to stop responding

[Start] - [Run] - type [Regedit] --[HKEY_CURRENT_USER]--[ControlPanel]--[Desktop], change the value data of the string value [AutoEndTasks] to 1, and restart it.

2, automatically shut down the stop response program when shutting down

In [Start]--[Run]--type [Regedit]--[HKEY_USERS]--[.DEFAULT]--[ ControlPanel], then change the value data of [AutoEndTasks] to 1 in the right window of [Desktop], log out or restart.

3, speed up the read-ahead ability to improve the boot speed

In [Start]--[Run]--type [Regedit]--[HKEY_LOCAL_MACHINE]--[SYSTEM]--[CurrentControlSet ]--[Control]--[SessionManager]--[MemoryManagement], in the right window of [PrefetchParameters], change the value data of [EnablePrefetcher] as follows, if you use the PIII 800MHz CPU or above, change the numerical data to 4 or 5 Otherwise, it is recommended to keep the value data as the default value of 3.

4, use the CPU's L2 Cache to speed up the overall performance

In [Start]--[Run]--type [Regedit]--[HKEY_LOCAL_MACHINE]--[SYSTEM]--[ CurrentControlSet]--[Control]--[SessionManager], in the right window of [MemoryManagement], change the value data of [SecondLevelDataCache] to the same decimal value as CPU L2 Cache: for example: P4 1.6GA L2 Cache is 512Kb, The numeric data is changed to a decimal value of 512.

5, run the Defrag program when starting the computer

In [Start]--[Run]--[Regedit]--[HKEY_LOCAL_MACHINE]--[SOFTWARE]--[Microsoft ]--[Dfrg]--[BootOptimizeFunction], set the string value [Enable] to: Y is equal to on and set to N equal to off.

Third, the registry optimizes the computer speed

1, clear the unused DLL file in memory

In [start]--[Run]--type [Regedit ]--[HKKEY_LOCAL_MACHINE]--[SOFTWARE]--[Microsoft]--[Windows]--[CurrentVersion], add an item [AlwaysUnloadDLL] in [Explorer], the default value is set to 1. Note: If the default value is set to [0], this function is disabled.

2, speed up the menu display speed

In [Start]--[Run]--type [Regedit]--[HKEY_CURRENT_USER]--[ControlPanel]--[Desktop], will The value data of the string value [MenuShowDelay] is changed to [0]. If you feel that the menu display speed is too fast after adjustment, you can change the value data of [MenuShowDelay] to [200] and restart.

3, speed up the automatic refresh rate

In [Start]--[Run]--type [Regedit]--[HKEY_LOCAL_MACHINE]--[System]--[CurrentControlSet]-- [Control]--[Update], change the value data of Dword[UpdateMode] to [0], and restart it.

4, speed up the boot and shutdown speed

In [Start]--[Run]--type [Regedit]--[HKEY_CURRENT_USER]--[ControlPanel]--[Desktop], Change the value data of the string value [HungAppTimeout] to [200], and change the value data of the string value [WaitToKillAppTimeout] to 1000. Also in [HKEY_LOCAL_MACHINE]--[System]--[CurrentControlSet]--[Control] Change the value data of the string value [HungAppTimeout] to [200] and the value data of the string [WaitToKillServiceTimeout] to 1000.

PS: However, it should be noted that there is a certain risk in modifying the win7 system registry, so everyone should try to back up before modifying, and need to be more careful when modifying.

The above is a way to speed up the network connection and system response speed of Win7. Are you still worried about the long response time of Win7 system program? Try the method described above.
