Windows 10: Moving Windows 10 License Key

I've done some searching but I couldn't find an answer...

I built a computer last year and bought Windows 10 from the Microsoft store to install on it. Microsoft emailed me the product key and it's been running fine for over a year. Lately, I've been having issues with it (hardware issues) and decided to build a new machine. I have a new motherboard, processor, RAM and M.2 SSD and I'd like to move the product key over. I believe I'm legally allowed to do that with the retail copy I purchased, though I'm not sure. So, questions are...

1) Am I legally allowed to move the product key over? I'm planning on only using the new machine. The old one is trash. If I need to buy a new license, then so be it, but I wouldn't mind saving a couple hundred bucks.

2) How do I go about it? I've seen deactivation videos on youtube, etc. Do I need to deactivate on the old machine? I should be able to keep it running long enough to do what needs to be done.

Any help is appreciated.

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

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?

 

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.
