My work PC has been a little sluggish lately so I decided I'd do a bit of spring cleaning on it today. Now I don't want to do all this manually so I start looking for a tool to do this for me. First stop http://www.hanselman.com/tools then search page for "temp" and sure enough Scott has found one.
CrapCleaner is a nice little tool and apparently this is something I should do more often based on how much it found to delete ( about 2.6 GB).
