There used to be an auto logoff screensaver (winExit.scr) in the Windows 2000/2003 resource kit, although it doesn’t appear to play too well with Windows 7/Vista. I needed the functionality that this provided for the systems in our meeting rooms, as people have a habit of leaving the systems logged on in there then leaving the room!
As I couldn’t find anything (for free!) that did this, I thought it was time for a bit of D.I.Y! So here we have my AutoLogoff Screensaver for Windows 7/Vista. Dead simple, drop in your C:\Windows\System32 folder, then probably use group policy to force it onto certain machines, or the local policy with gpedit.msc! Dims the screen like a UAC prompt in order to try and get the users attention a bit more, there’s no configurable options at the moment, just 60 seconds warning until logoff. If I get alot of requests I might add some additional funtionality, but it’s serving my requirements now, so I’m happy ;)
Update 06/09/10: I’ve now added the ability to change the amount of time the warning lasts for, you can either leave as the default 60 sec, or create a reg key in HKLM to set your own – see readme file for key name!
