The computer I have right now was a custom build that I did a few years ago, and I upgraded it with Win 7 Ultimate 64bit OEM about 5 months ago, which I purchased from Newegg. If I'm replacing the MB, HDD and such can I reuse this license to reinstall on the new Drive, assuming I delete the OS off the old HDD?
If your mobo dies, u can replace it and use the licence.
The replacement must be equivalent of the old one.
This must be activated over the phone with MS.
This restriction is there because u have the licence with great discount.
