I am looking for a program that reliably prevents the computer from shutting down. This can be useful in various cases:
- during PowerPoint presentations
- while running a huge download over night
- when backing up an entire disk
The tool should
- be gratis
- run on Windows 7 and higher
- prevent shutdown done via the
shutdown
command - prevent reboot due to Windows updates
- prevent shutdown via power button switch
- prevent reboot of other installers (whatever software might cause this)
- just do this and not a bunch of other stuff like some system enhancement tools do
I have tried the Registry switch HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU\NoAutoRebootWithLoggedOnUsers
but it was not very helpful and applies to Windows Updates only, not to other software.
