Hey Guys i'm planing to do a clean installation on my current OS(win 7 home premium) to Win 7 ultimate...my OS is on C drive...and all my precious files(games,music,vids...etc) are stored D,E,F...should i proceed with the installation or back it up on an external HDD???...Help is appreciated!!..thanks
If it's just the OS drive being replaced then it shouldn't be a big issue. However if you clean install the OS, you will have to reinstall all your software/programs. Data files (music, videos, documents,...) will be fine.
