Windows 10: Lost my windows product key after a factory reset and reinstall windows.

I reseted my computer to clear everything and start the computer as new.But when I was done it said that my key would stop in a couple days, then it said for maybe 3 days. Now I only have "Activate windows"glued stuck to my screen at the bottom right of the screen. And I have reseted my pc before and this has never happened then. I have searched up on youtube and so on but I can't even find my product key.

Did a factory restore and it reverted back to 8.0. I lost the 8.1 update and windows 10. I lost my product key as well. I have to have step by step instruction to get lost updates of windows8.1 and windows 10 back.

Reinstalling windows 10 after factory reset

Greg,

Of course I tried everything else first, my last choice is a factory reset because I don't want Windows 7 back with Internet Explorer 9, its so outdated I can't surf the web. (And don't even get me started on IE11). Reinstalling Windows ran into a problem
and wouldn't complete. However, this doesn't even matter now because I already did the factory reset and my PC is up and running again. My problem is getting Windows 10 back.

Windows 10 setup does NOT ask for a product key, there is NO step to skip. It runs thru the entire download and installation itself without ever even mentioning a product key until it stops to tell me it failed to validate product key, that's when its over.
The end, it does not give me any options from there.
