Windows 7- Student Discount

hi, i've just ordered the student discount, Windows 7 Professional for $29.99. My question is how do i make a CD copy? So i can have a back up of it. Thanks

Make bootable iso from student d/l

just wondering is there a need to make a CD copy? can i just download the exe file and run it?

Probably - you can copy the files to cd in the normal way - in case you need them again.

ok cool, so i just need an iso program to burn to cd right? i'm kind of confused about post number 2, which option do i use to copy to a CD?
