The Free Windows 10 Will Support Unlimited Clean Installs

So Once it is upgraded to windows 10 before 2016, I can use my windows 8 key for activating windows 10 OS rite?

You have to upgrade to 8.1 and that key will work, if you did not use it to upgrade previously.

Sure it did, 8.1 Pro. From previous post #41... The whole reason for trying to do this was to be able to use the Win 7 license to get Win 10 on 7/29. And keep my Win 8.1.

But, oh well, can't get there from here. It's ok, I'm just a pack-rat and like to keep old stuff (like 7).

OK, I get it now.

Back when I worked as a volunteer rebuilding donated PCs for re-donation, we couldn't get that to work; only occasionally did the reinstall media come with the PC. However, one large corporation donated a bucket load of PCs and Windows 98 disks packaged with their keys. Lots of folks got helped by those computers!

I have used that 8 key for 8.1 installation.

Without the requirement of a license key, that will make activations a lot easier.

It's not going to try and insert it's own license SLIC into the Motherboard? In which case changing out the Mobo would actually stop this working..

We are all in uncharted waters, but I do not think you can dual boot. I think that once you go to 10, your 7 or 8 will no longer validate.

Sure I can.

On one computer (probably this desktop), I won't let Windows 8.1 upgrade to Windows 10. I will most likely also use this desktop for the Windows 10 continuing Insider Program.

Well, Rich, you've started me on the way to figuring out how I'm going to work with Windows 10 and Windows 8.1.

I have three laptops, two of which are dual boot. On Lappy 17, I'll let Windows 8.1 upgrade to Windows 10 and keep the Preview as the Insider Program. That's as far as I'll go for now, since I have another 17" (pretty old) laptop and a 15.6" as well.
