A friend of mine wants to reformat his Dell Laptop, which has a Vista OS. His reason is that he wants to start over...fresh.

I had run some AV/AS/AW scans and he had some rogue programs and some minor infections (uses P2P). So that, combined with "2mb of memory left" (his words, I didn't check), he wants to start over with a new install.
I checked out the Vista Tutorials, but the "Repair" section seems to offer recovery instructions, but no Reformat instructions (i'm not familiar with Vista). I did some Google searches for Reformatting Vista, but thought I would ask my BleepingPeeps for guidance, as I value your knowledge and experience.

Thanks in advance.
Doc.
