Microsoft is working to fix the situation. With insider build 10565, they are allowing activation by manually entering a Windows 7/8/8.1 Product Key. Hopefully this gets incorporated in the major Windows 10 update release they are saying will happen in November.
Glad I could help solve your problem. Showkey Plus has several unique features that other product key sniffers do not have - the ability to read the product key that was previously used for an upgrade, the ability to read a product key from a back-up image, and the ability to manually enter a product key and it will tell you what version of Windows 7/8/8.1/10 it is for.
Superfly gets all the credit for Showkey Plus. He's pretty amazing when it comes to Product Key stuff.
