Auto Shutdown Genius
Full user review
It does what it says it will do, I will say that. Written fairly well in that it has no conflicts with Windows 7 Home Premium. It installed and uninstalled cleanly so that's a plus. All of the options written work as well.
If you're looking for this program to just shutdown your PC after a given amount of time, it will certainly do that. However, whether you are using the computer or not it will shutdown on you after the time you set has elapsed, period. Idle or not.
The knowledge base FAQ is pretty much non-existent on the vendors website. The only help you'll get there is how to install it, run it and uninstall it. As far as the company's claim that it will run on Vista and Win7 is a thin claim.
I contacted the vendor with the "idle" issue I mentioned previously and was told, and I quote, "We cannot fix that on Vista and Win7."
