Windows 10: Lost Windows 10 Activation Key

Hi, I recently purchased a Windows 10 Home product off of Amazon, complete in box. I didn't realize the activation key was on paper in the box and threw it all away. When I inserted the activation media, it prompted me with the watermark in the bottom right corner asking for an activation key to activate Windows. Amazon doesn't give an option to contact the seller, and I was wondering how I would contact somebody to get a replacement key.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
