That being said, we would encourage everyone to upgrade because Windows 10 is the best Windows ever – familiar, safer, faster, and full of innovations. After any upgrade, you can easily go back to your prior version of Windows within 31 days if you choose. We do this by keeping a full copy of your previous operating system on your device – including apps and settings – for the first 31 days following your upgrade. At any time during the first 31 days, you can go to “Settings->Update and Security->Recovery and Uninstall Windows 10” to return to your prior version of Windows.And of course, if you choose to upgrade, then you will have 31 days to roll back to your previous Windows version if you don’t love it.Ok we get it... 31 days. What happens after that? Some have stated their old PID keys still worked after 30 plus days when they decided to revert back to their old OS so that's good news. But I also note here how many times MS stressed 31 days so I wonder if there's more to come after that should one take longer than 31 days to revert back? Seeing how "aggressive" Microsoft is going to get in pushing Windows 10 out who knows what this might mean in the coming months?if you choose to upgrade (our recommendation!), then you will have 31 days to roll back to your previous Windows version if you don’t love it.
Just a thought.
BTW I'm running Windows 10 on two machines and loving it, so my question is not MS hate. Thank you.
