Windows 10 fresh reinstall licensing quetion

post #1 of 12
Thread Starter 
I did the in place upgrade to Windows 10 back when it first came out. Since then I have had issues with lag in a number of games, netflix, etc. I have redone drivers, applications, games, nothing fixes it. What I would like to know that I haven't found a good answer to is how the licensing works after an upgrade and then doing a reinstall. Does anyone know if I can use my old 7 key as it was "upgraded" to a 10 key? Or is MS going to make me get a new key as its no longer an upgrade but a clean install?

No key is needed. Just install a fresh copy of 10, go online and it will auto register. It works by checking your motherboard's unique identifier to see if the system has been activated previously.

Here is what I got from Microsoft's site. https://www.microsoft.com/en-us/software-download/windows10

"If you haven’t upgraded to Windows 10 yet and perform a clean installation, you’ll need to enter a qualifying product key for Windows 7, Windows 8.1 or Windows 10 or buy a license in order to activate Windows 10. Click here for information on qualified editions."

I have Windows 7 and have already registered for 10. I am just going to use their utility to make a Windows 10 install USB drive, and plan to just have to enter my supplied Windows 7 license key. Fingers crossed that it all works. I'll update here if it does or does not.

You don't need the key if you upgraded to Win 10 on the same system previously. Read my first post. wink.gif
If it did ask after you've installed the OS, that just means the auto authentication timed out. biggrin.gif

I haven't installed Windows 10 on the machine yet. I was wanting to do a clean install versus an upgrade.

Ahhh right. Sorry I thought you had upgraded.

I had an issue on my laptop where I could no longer boot into Windows. I'd get a boot loop on the bios screen. I had to do a total reinstall of Windows with a fresh clean install. I had to enter my previous windows 7 key in order to get win 10 to activate.

And it worked?

I ended up doing a regular, upgrade install, then wiped the drive and done another fresh install. Worked fine.
