Is there a way to skip the standard Windows shutdown procedure and instantly poweroff a computer?

You know that that's basically equivalent to forcing a crash, right? In the sense that the computer isn't able to shut itself off properly (because doing so takes some time), and files could be corrupted when it starts up again. – David Z Jun 28 '10 at 8:19
Basically, yes. It sounds like a stupid idea when you put it that way, but if there was some way to control the crash...or even to force a bluescreen, it would be useful. – user41213 Jun 28 '10 at 8:24

There are some 3rd party programs to do it. For example, Instant Shutdown from Zazub.

Instant Shutdown is a C++ program that instantly powers off your computer when run, as if it were unplugged. Careful when using it, as Instant Shutdown does not ask for any type of confirmation, and all unsaved work will be lost. Instant Shutdown does not generate any Windows improper shutdown error messages, so use it to replace the default windows shutdown option and save yourself 20 seconds.

You could reduce the shutdown time using this registry tweak. Save the following as shutdown.reg and double click to export into registry. (Please take a back up of your registry before)

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]


[HKEY_USERS\.DEFAULT\Control Panel\Desktop]

I saw this same script during a bit of research, but I was hoping for something sub 5 seconds (security program) – user41213 Jun 28 '10 at 8:20
