Guess I'll continue to dual boot with 7 and insider until they get major bugs stomped out, or a year passes, or the insider program is shut down, whichever comes first then I'll upgrade from 7.
What I think will happen is that first we have to accept an upgrade (unless we upgraded our Win 7 or 8.1 systems to Win 10 at the beginning) to Windows 7 or 8.1. After that, we can use the ISO to reinstall Windows 10 as a clean install. And, yes, I hope that's not the way we have to do it, but it seems to be what we're being told. That is if I'm reading my tea leaves correctly.
Senarie: Running windows 8.1. Upgrades to windows 10. Run Windows 10 for a week. Buy a SSD. Take out the old HDD, and mount the SSD. Now clean install windows 10 on the new SSD.
Question: How does the new installed Windows 10 "know", that I have upgrated from windows 8.1 at an earlier state??
I'll get new keys through MSDN anyway, so it doesn't really matter to me if I do the free upgrade or not. I likely will on at least one PC just to see how the whole process works etc. It makes sense to me what they did. If you stay an insider your RTM build comes as just another preview build with a fixed expiry date like any other preview build. Opt out and you have to install another OS on that PC when your Preview expires. If you qualify for the free upgrade, you can then do that if you want. Then your RTM build becomes a fully licensed Windows 10 install. I have a PC that I upgraded to the TP from Windows 7. It's 10 Pro so I think that's the one I'm going to do the free upgrade on to a full version. My laptop is running 8.1 Pro activated with my TechNet 8.0 Pro key. I may try that one too just to see what happens. It also has an embedded OEM key for 8.0 Core. It has the GWX icon saying its good to go. For me its more for testing purposes than getting a free upgrade to 10. I want to see the upgrade process first hand so I can answer questions accurately.
Oh, well, at least I know where I stand now i.e. no freebie for wife's Vista!! Had my hopes raised there for a short while.
Think I will buy a used PC with Win 7 Pro on it as it would be cheaper than buying win 10 on its own. But the downside is the upgrade to win 10 would be OEM. Hmmmmm. Decisions, decisions.
Maybe, like Bunny, I just cough up for the retail version in August and move on.
Everyone needs a laugh and I still am not convinced of anything. Can I keep Win 7 and Drop out of the TP after the 29th.?
