"Devices Directly connect to Windows update so those devices get the Yada Yada as soon as they are available" approximately at 16:00 to 16:12 minutes
There's some Windows activation (besides buying a key) that's more likely to allow the Windows 10 upgrade in the future? Win7 with Win Loader, Win8.1 with kms, or other kind of activation?
At the very least, Windows 7 with loader should work (for one thing, Technical Preview was delivered to Windows 7 users via Windows Update), but honestly with the way Microsoft's been trying to put their latest stuff in the hands of consumers I'd imagine it'll be as simple as signing up to get an upgrade key, much like the way Microsoft provided free keys for Windows 8 Pro with Media Center as an upgrade for early Windows 8 users. Point being, I'd almost be willing to place money on you not even needing Windows to be activated prior to a free upgrade to Windows 10. They'd rather you pirate it than not use it at this point.
I have absolutely zero faith in them letting KMS pass. A legit KMS customer would get a new key most likely. Downgrade to W7 and loader it, unless it binds to the SLIC being there and deactivates. But hey, lots of us have devices with SLIC built in, no bootloader required.
This Agreement is only for the Windows Insider Program. Not much has changed from the original document that you agreed to when you signed up for the program. What has changed from the previous version is some things in section 13 & 14.
Your device, heck it's just free... it's just legal things you really don't should care about. If you buy a new device is has Windows 10. If you keep using your Device it has Windows 10, if your device dies.. well needless to say you can't use W10 if it's dead. Also there are things like CPU feature requirements a new W10 build could bring that makes your device "unsupported" because it doesn't support a new instruction set, that's what it means. Equally some very old W7 PC's can not update to W8.1/W10 because they don't support some CPU instructions so these devices are "unsupported" > no free upgrade (not possible anyway!). Needless to say it's likely you will still be able to transfer licenses just like we did before via Phone activation as Microsoft can not invalidate licenses just because your Mainboard died etc not to ignore that in Europe you are allowed to transfer licenses more or less TL;DR Nothing changes.
I Agree, nobody cares, I just want the new build, people are over sensitive, if you're going to be like this just stick to 7, MS Are offering FREE upgrade for the whole first year, you still have time to decide, no one is forced to use it, I like 7 but I prefer new features and staying up to date to new OS and less security flaws, better and faster experience also matters to me and thats all.
