Can i upgrade to Windows Media with an 80gig hard drive?

Answer 1

You sure can , just keep an eye on what you put on and what you have left . 80 is a lot unless you are using high def movies to store

Answer 2

YES of course.

But if you have some money to spare and a vacant bay, you could consider adding another hard drive. They are SO CHEAP nowadays. I just bought TWO new 80Gb (1 SATA & 1 IDE) 3 weeks ago for ONLY $63 total. My first and oldest 80Gb drive cost me $58.
