I'd say you need to be more specific as to what your goals are here if you hope to get any answers. This question is too vague.

I hope you find this post helpful.

there are power API calls that might be of interest

Sorry for the delaied clarification...
I need the time of inactivity like the one after the screen saver starts.

I don't think you will be able to get that granular. As soon as you query I think it will alter the inactive time.

I hope you find this post helpful.

There is a [tt]GetLastInputInfo()[/tt] in [tt]user32.dll[/tt] that will return the time of the last user input (keyboard or mouse I believe) in milliseconds since last reboot. This requires Win2K or later.

There is also a window message broadcast to all windows relating to expiration of the screen saver inactivity interval. I can't recall the name and value of this message right now. Probably a WM_SYSCOMMAND with an argument like SC_SCREENSAVE. Ahh, I think that's it, see: How to write a 32bit screen saver.

Neither of these is directly useful from a WSH or HTA script however. You'd need a code component created using VB or C++ to make the API calls needed, and you'd need to intercept window messages to use the other approach.

Maybe someone else has another answer, possibly via WMI?
