Here is my friend’s scenario; he has Windows 7 HP SP1 OEM on his Fujitsu laptop, the Windows Update kb3035583 would not install as the kb2952664 had not installed either. He joined the Windows 10 Home Insider Program and has had updates up to Build 10162 and no further updates to 10166 or to 10240! The build 10162 is activated and expiry date is 2nd October 2015.
He does have a backup of Windows 7 prior to joining the Insider Program.
Question 1. Will he receive the notification to upgrade for free to Windows 10?
Question 2. Can he upgrade to Windows 10 final version using MCT Upgrade option?
Question 3. What would happen when the 10162 build expires, would it roll back to Windows 7?
