Why are you trying to delete the file anyway? If Unlocker doesn't work and the file is locked after you disable WFP then you'd have to boot to a CD with a file manager (Knoppix, ERD Commander, Reatogo Builder, BartPE) and navigate to the directory the file is stored and use the "del" command.

If you want to remove Vista, then boot to your XPCD and format the G drive.

In my opinion, that's a lot of work just to delete one file, which brings me back to my first question, why?

Open the file's properties dialog---->Security tab----->Advanced button---->Owner tab--->Select administrators---->OK button

now, this file's owner change to current admin, and you can del it.
