As it says in the title my computer is currently full of junk and my files are a complete mess. So I wish to wipe my computer and install Win 10 when it comes out. However only this year I have brought a version of Microsoft office and I still have the product key written down. When I wipe my hard drives and start fresh will I be able to redownload it and renter the product code or will it reconsign my Microsoft account or something like that? Because I have only brought it recently it seems like a huge waste of money to have to buy it again!
Thanks for your help!
