Windows – Lock Screen after screensaver starts + delay

lock-screenscreensaverwindows 7windows task scheduler

I would like to have my win7 desktop lock after say 15 minutes of idle time. I also want my screensaver to start at 5 minutes of idle time.

I tried using programs that run a command after a certain amount of "idle" time, like Idle Start or Idle Controller. These programs however, seem to calculate idle time themselves, based on mouse movement and keyboard activity. And this will lock my screen while I'm watching a movie.

When you watch videos, your mouse and keyboard are idle, but Windows knows not to start the screensaver or turn off your display.

Is there any method to attach an event (lock the screen) to whatever Idle timer Windows uses, the one that is aware of videos and games and whatnot?

Alternatively, it would be awesome if I could lock the screen when my monitor turns off (which is already set at 15 min).

[EDIT]

In case anyone is unclear, I do not want my computer to sleep. There are settings in Windows to lock the screen: 1. on screen saver, and 2. on wake. I do not want either of those.

I was asking if anyone knows of any "arcane" tricks. Could Task Scheduler or a registry hack help?

Best Answer

Set your screen saver to lock when it comes on, then open regedit.exe to 

HKey_Local_Machine\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\

Find the entry on the right hand side of the screen for ScreenSaverGracePeriod (if it's not there, create it as a REG_SZ. Add (or change) the value to be 600 (that's 600 seconds, or 10 minutes).

Now, your screen saver will come on at 5 minutes, and you have an additional 10 minutes past that to wiggle your mouse and come back. After the screen saver has been on form 10 minutes the computer will automatically lock itself.
