modify the registry to speed up Windows 7 system boot speed
1) Run regedit into the registry.
2) Open to: HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\PrefetchParameters
3) On the right side of the "EnablePrefetcher" primary key, change its default value from 3 to 0.
4) Restart your computer
modify the registry to speed up Windows 7 system shutdown speed
1) Run regedit into the registry.
2) HKEY_CURRENT_USERControl\\PanelDesktop, set the key value of "AutoEndTasks" to 1.
3) Then modify "HungAPPTimeout" to "4000 (or smaller)" (default is 5000), the key value is also under "HKEY_CURRENT_USERControl PanelDesktop"; the last step to find "HKEY_LOCAL_MacHINESystemCurrentControlSetControl", also the WaitToKillServiceTimeout is set to "4000";
remove the menu delay time of the delay
remove pop-up menu can be accelerated to some extent Window7. The key value to be modified is in the "HKEY_CURRENT_USERControl PanelDesktop". Modify the "MenuShowDelay" button under it, change the default 400 to 0, press F5 to refresh the registry, and the restart will take effect.
Shortening the waiting time before closing the application and the process
Similar to the waiting time before shutting down the service, Windows Vista also has a section before forcibly closing the application and the process. Waiting for the program or process to close itself, the Windows system will force it to abort only after the time limit is exceeded. Therefore, shortening the default shutdown of the application or waiting time can also speed up the shutdown of Windows 7.
The setting method is similar to the above. Find the following branch in the registry: HKEY_CURRENT_USER\\Control Panel\\Desktop, double-click "WaitToKillAPPTimeout" in the right panel, and change its value from the default 20000 (the unit is also milliseconds) to A small 5000 or 1000, so if Windows does not receive an application or a shutdown signal after waiting for 5 seconds or 1 second after issuing a shutdown command, a corresponding warning signal will pop up and ask the user whether to force abort.
