When I finished rebuilding my last desktop computer with a new motherboard and related components, I needed to reactivate Windows due to the hardware changes. It means moving the retail license to the new motherboard. I have done this before, but this time I could not. The troubleshooter didn't work, and most of the pages and links were greyed out. The only choice was to give Microsoft my phone number for a call back. This is the process that I followed.
