Sorry for dumb question if already asked, but did not found exact response. A friend of mine has an Home made PC with a legit Windows 7 Ultimate x64 on it. He grabbed a Win10 10240 ISO made from an "install.esd" , then ran setup after mounting the ISO file. This was yesterday. (He could not resist to wait 12 day more !! ) He told me the installation went fine, and his Windows 10 pro show "activated". I ask him to check the status using slmgr -dlv and the 4 last four digits of the key are "3V66T". His question is : Does this installation will be upgraded after July 29 to final release ? He was not asked for creating an MSA account during install. Any advice appreciated , he has cleaned Windows.old with Ccleaner so cannot reset to Win7.
