Upgrading my MOBO,RAM and CPU next month.Formatting SSD and fresh installing my windows 10 64bit home.I bought this copy of windows like a year ago from newegg for $100,i have the CD and the CD key but will be installing with a USB drive.Just curious if i will have to buy windows again or if it will let me change my hardware and still let me use my copy of windows.Its a OEM copy and i have it linked to my microsoft account/outlook.
