I don't know if this is something I should be able to figure out using a native capacity of Windows XP, or what. I've been contemplating a clean install of Windows for a while, and as part of that I want to clean up the clutter on my hard drive. There are zillions of little programs and such that I have downloaded, most of which I never use, some of which I use all the time, and some of which are probably running and doing useful things right now but which I have been using for so long that I have forgotten I installed them.
What's the best way to see how often a program actually runs? I was thinking that it would be nice to have something spreadsheet-like, that will tell you how many times a program was started and how long it was active in a defined period of time (in the last year, last 6 months, since Windows was installed, etc.). Presumably there is a way to get at this information somewhere in Windows, but I don't know how to get to it.
