I am running Windows 7 with 4 gbs ram and a dual core 3 ghz processor
What the heck is this thing doing except keeping my power company in business
While you're upgrading, check your current agent version. While 4.0 sorta works for win7 (or did for several of our test machines before I became aware....), I believe 4.5p1 or better is where you need to be to be considered officially supported on win7.
