How do I subvert computer idle detection on Windows?

In order to detect user absence GetLastInputInfo() can be used.

I want to make GetLastInputInfo() return that I've just used keyboard/mouse all the time - as I've been actively using the computer so that whoever relies on GetLastInputInfo() thinks I'm actively using the computer.

Can I use any Windows API functions to achieve that?

What is this for? Do you just want to disable the screensaver? If that's the case, then you're probably better off looking at the SetThreadExecutionState function.

The other options are:
