Just wondering if anybody has upgraded a Windows 7 family pack (Upgrade media), which is basically a 3 pack windows 7 home upgrade version containing 1 licence key that can be installed on up to 3 computers to windows 10 via the free upgrade version. If so what was the procedure you used to upgrade all computers?
Im finding conflicting information and not sure the exact procedure to use?
I assume MS helpdesk is no help?
I would try burning a disc from the ISO file and use in all three. I did a single license upgrade this last week using that method (so if I have to reinstall I may save on download time etc).
It picked up the already installed key (from win 8.1), perhaps it would do the same on your three.
