Seems an ideal way to preserve the drive in case you forget something without having to save the physical drive - he could wipe the drive and sell the desktop knowing he had a back up of the original drive just in case.
Even in that situation, your best bet is to backup all your data to another drive (or laptop in this case). That way you wouldn't waste so much hard drive space, there isn't any plausible reason for needing to back up your temp files, cache folders, .exe files, & all that other stuff.
I mean, if you really wanted you could also create an image of the drive (which still backs up all the crap you don't need, but at least you know you backed up *everything*). Even a drive image is better than doing virtualization. Gotta agree with Budman, virtualizing is way overkill in this scenario, but maybe the OP has some other reason for needing it?
