So, I've never been part of any Windows Preview, just Windows Phone.

The preview will allow me to use the system up until May 2015. I wonder what will happen after that timeframe is over?

I have a Lenovo x220, which came with Windows 7 Professional. I also have the serial key for the upgrade to Windows 8 Pro. Do you guys have any idea if it will work when I install Windows 10 final? Or I will have to downgrade to Windows 7, update to 8 and then to Windows 10 (assuming it will be a free upgrade, as rumored)?

How did that work when the Windows 8 preview was available?

Im asking that because I went full commando and installed W10 after a clean format on main computer's C: drive hahaha

Downgrading won't be a problem, but I'm REALLY lazy to do that.

Historically, upgrading from a beta to a final release isn't an option.

I heard of it being POSSIBLE, but I wouldn't bank on that.

After the thing expires, I know Windows 7 Release Candidate would reboot randomly after a certain time period of on-time IIRC, i could be wrong though.

I'm not sure about the upgrade path though, I'd upgrade starting at 7, but eh, I don't know for sure.

I suspect there will be either an upgrade trick to create an ISO or ISO available and all you will need it to verify your windows 8 eligible for free upgrade key.

That would be my guess...it was possible to install a clean 8.1 using these tricks.

Since this is 10...pretty sure they won't want to try to tie it to obscure upgrade path that's tied to having 8 installed and upgrading that..i would be surprised if there was not a much easier clean path since this is a Major version release.

That date is just picked from the ether. Expect to see a Technical Preview update that will push the date up to or beyond the official release date.

No, you will not be able to upgrade from a technical preview to final release. Reason: licensing in the release version will conflict with technical preview by design.
