Modify the registry to speed up the Windows 7 system shutdown speed
1) Run regedit to enter the registry.
2) HKEY_CURRENT_USERControlPanelDesktop, set the key value of “AutoEndTasks” to 1.
3) Then modify “HungAppTimeout” is "4000 (or smaller)" (default is 5000), the key value is also under "HKEY_CURRENT_USERControl PanelDesktop"; the last step is to find "HKEY_LOCAL_MACHINESystemCurrentControlSetControl" ;, also set WaitToKillServiceTimeout to "4000";;
remove the menu delay
remove the delay when the menu pops up, you can speed up Window7 to some extent. The key value to be modified is at “HKEY_CURRENT_USERControl PanelDesktop”. Modify the "MenuShowDelay" key under it, change the default 400 to 0, press F5 to refresh the registry, and the restart will take effect.
Short wait time before closing application and process
Similar to waiting time before shutting down service, Windows Vista has the same time waiting for the program or process to close itself before forcibly closing the application and process. After this time limit, Windows will force it to abort. 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. Locate the following branch in the registry: HKEY_CURRENT_USERControl PanelDesktop, double-click "WaitToKillAppTimeout" in the right panel, and change its value from the default 20000 (the unit is also milliseconds) to the smaller 5000. Or 1000, in this way, if Windows does not receive an application or a shutdown signal after waiting for 5 seconds or 1 second after issuing the shutdown command, a corresponding warning signal will pop up and ask the user whether to forcibly abort.
