1. Reduce Timeout To Kill Service Or App
Before Windows shuts down, it attempts to properly close all running processes. If a service doesn't close immediately, Windows waits for a few seconds, until it prompts the user that the service is not responding to the shutdown request. The amount of this waiting time is defined by registry keys and you can reduce it.
These are two fairly harmless registry hacks. If you follow the steps outlined in this article, it should in no way harm your system. Nevertheless, I have to issue a warning:
Editing the registry can damage your operating system! I or MakeUseOf take no responsibility whatsoever! Make a backup of your registry before continuing.
For the first hack, click the key combination > [WINDOWS] + [R], type > regedit into the text field, and click > OK to launch the registry editor.
In the registry editor, navigate to this folder:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
Within that folder (on the right) find and double-click the string > WaitToKillServiceTimeout.
In the > Edit String window, change the > Value data from the default of 12000 (12 seconds) to 2000 (2 seconds). Click > OK to save the change.
For Second Hack
HKEY_CURRENT_USER\Control Panel\Desktop
On the right, find and double-click the string > WaitToKillAppTimeout.
If this entry does not exist, you can create it. Right-click into the folder and click through >New > String Value, and name it > WaitToKillAppTimeout.
Set > Value data to 2000, click > OK.
In the same registry folder, if you see an entry called > AutoEndTasks, set its > Value data to 1, then close the registry editor.
Shutdown time: 27 seconds
2. Create a Fast Shutdown Shortcut
As of Windows 2000, Windows has come with a remote shutdown tool to shut down and restart Windows. You can control this tool through the command line, but a much faster alternative is to create a shortcut.
§ Right-click your Windows 7 desktop and select > New > Shortcut.
§ Enter > shutdown.exe -s -t 00 -f in the location field, click > Next, give the shortcut a descriptive name, e.g. Shut Down Computer, and click Finish.
The letters (options) added above tell the tool to shut down (-s) with a timeout of zero seconds (-t 00), and to force running applications to close without forewarning the user (-f). Basically, it unites the registry hacks from the first tip in the shutdown process. You can see a full list of options when typing > shutdown.exe into the command prompt, which you can open via > [WINDOWS] + [R] then type > cmd into the text field and click > OK.
You can move this shortcut from the desktop to your quick launch bar or pin it to the taskbar. Double-click the shortcut to instantly shut down the system.
Shutdown time: 24 seconds
3. Brute-Force Method
This method is also known as hard boot, as it is typically used to shut down and immediately reboot the computer. It should be used with extreme caution!
If you're in a hurry and cannot wait for 20 seconds or if your computer responds slowly or even froze, simply hold the power button for several seconds and Windows will shut down immediately. Since this method literally kills not only the operating system, but also the hardware, it should not be used as a routine way of shutting down your computer. In a worst case scenario, it could cause your hard drive to crash.
Shutdown time: 5 seconds
