NonStop

NonStop allows one to deactivate/hide the possibility of shutting down (or sleeping) a Windows system.

Building

Get the source (Cloning/Downloading)
Open the NonStop.sln with Visual Studio for example
Build the project
There should now be a NonStop.exe which you can run

Notes

The program was tested on Windows 10 x64.

How does it work?

NonStop alters registry values in the background so that shutting down/sleeping is not possible anymore on the given machine.
(Look at src/NonStopTool.cs to see the mentioned registry keys)

Limitations

The program cannot currently stop a user from shutting down a system via PowerShell/CMD which is not easily possible.
