Activation error message on upgrading from 7 32 bit to 10 64 bit
So I followed the guidelines on how to upgrade, which meant upgrading to 32 bit windows 10 and then doing a clean install to go from windows 10 32 bit to windows 10 64 bit. My original windows 7 installation was an activated copy but I don't know if I have a record anywhere of the product key.
I have just realised (about 72 hours after the 64 bit clean install) a semi-transparent message on the desktop telling me to activate windows. Any ideas folks? Am I going to have to find my old key, use it to install windows 7 64 and then upgrade again? According to everything on the net this should not happen.
Cheers,
Dave
