Windows 10: I have a computer with Windows 10 Pro installed without a Product Key and no repercussions.

I purchased a computer made in 2008 from a trading site. It came without a hard drive. I installed a new SSD and downloaded the Media Creation Tool and installed Windows 10 Pro 64-bit. I installed it without a Product Key. I read that there would be a watermark and I would have to purchase Windows 10 to remove the watermark. But there was no watermark. This was almost a year ago that I did this. I also read this could happen eventually. Never happened. I have another computer with Windows 10 Home Edition 64-bit. I see both computers say "Window's is activated with a digital license

:)

 

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.

 

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.

 

Clean Windows 10 (?PRO?) install

As far as I am aware there is no Windows 10 Pro version.
But I'd be happy to be wrong.
