Xampp renamed my hard drive--how to fix?

[Fiddler]

My teacher distributed XAMPP on a stick drive and somehow had his name on it. When I applied it to my C drive, it renamed my drive. I've tried renaming my drive (by right-mouse clicking on it, selecting "rename" and typing c:) but it keeps coming up "Uncle Dave's apps (c:)" instead. How do I get his name off my c drive? I know this isn't exactly an XAMPP thing, but somehow installing it renamed my drive, so I need to know how to not do this in the future, after fixing it. Thanks for any help.

Hello and welcome Fiddler.

What does your teacher suggest? It was something on his disk, so he should have an idea?
