So we will only have 1 active version running at a time, right?
Also, others have commented to my post and confirmed what I need to do when it's time.
Lastly, a tutorial on what to do for the 29th could be helpful if there isn't one already. Just a thought.
This paragraph gives us the rules for continuing as an Insider:
The paragraph below gives us the exceptions to the rules:If you don’t have your Microsoft Account (MSA) connected to your PC, starting in the next build you’ll start seeing notifications asking you to do so. You’ll need to connect the MSA that you registered for the Windows Insider Program with (and accepted the “Microsoft Windows Insider Program Agreement”) in order to continue receiving new Windows 10 Insider Preview builds (both Fast and Slow rings) from Windows Update. If you already have your MSA connected to your account on your PC, then you’re all set. We’re introducing new infrastructure in Windows Update to help us deliver new builds more effectively to Windows Insiders, and ensure that we’re flighting builds to people who have registered and opted in to the program. Connecting your MSA also allows seamless access to Windows Insider-only functionality in the Windows Feedback app and Insider Hub too.
This change is for the Windows Insider Program ONLY, and is specific to how we’re delivering the
Insider Preview builds. Once available on July 29th, you do not need an MSA to upgrade Windows 10 on your Windows 7 or Windows 8.1 PCs if they are not receiving Insider Preview builds. You will not be required to use an MSA on
new PCs that come with Windows 10 preinstalled or clean installed from media. Some features in Windows 10 do require an MSA to use, such as downloading apps in the Windows Store
If that really the case, unless someone has a bunch of windows 7/8.1 home or pro disks people wouldn't upgrade to windows 10. With the retail version of windows 7/8.1 you are allowed to transfer to another computer. You have to remove if possible from one computer and put it on the new computer. You might have to call Microsoft and tell them you moved it. That why retail version cost more.
