I know that somewhere in the MicroSoft Windows 7, there is a program tool that will allow me to change the time before my computer shuts down. Lately I am having trouble because my computer will go back to the home page when I'm not ready to leave a program that I'm looking at. I need to change the time to allow my computer to stay on longer!

Type POWER OPTIONS into the search box,
This will give you he Power options and then it's simply a case of changing the active power plan..
