How to prevent windows from sleeping in C#?

Question

See more:

I tried moving the mouse programmatically but this didn't stop the "away from PC" because the user didn't do the move instead of the keypress that may be problematic.

What I have tried:

I simulate a keypress for Ctrl but I want to move the mouse 1 pixel to the right and then one pixel to the left and have the PC stop the away from PC time.

Why not just tell the user to change the power settings?

The idea of "Caffeine" program is taken from Linux, it prevents PC from sleep without changing the power settings always.

Here's my program and the source code.

I tried 2 codes for moving the mouse, the mouse moved, but the PC knows the user didn't do this so the computer remains in "away" mode.

You can use SetThreadExecutionState with ES_SYSTEM_REQUIRED
Note: its a native method.

But if the PC shuts down unexpectedly or the program terminates unexpectedly this remains and the computer doesn't sleep forever.

Does this have to be annulled after use?

Is there a way to move mouse and make the PC think it's the user who did it?

the system will discard the set flags when the thread that set it is no longer exists/killed (normally or abnormally)
