Hi pooch,
Have tried it myself and it found 297
applications on my Vista install less than that on my Windows 7 test install. It was a useful exercise as a few of them I installed a while ago and not had used since the initial try-out
It cleaned a bit of space anyway
One thing to look at is the 2 settings (just the start menu or in depth scan of Program files folder). It also displays a lot of Microsoft excecutables which are probably things I'll never run directly
Quite a few minor updates (and a few major updates where I have old versions installed because I cant/won't afford to update them
)
What I did like was the ability to send the list to a spreadsheet, (now that will be useful on other peoples machines)
