Windows 10: WIndows EDU and OEM Licence

My Son has a Dell Laptop that came with OEM Windows 10.

He has purchased a desktop, and wanted to activate his Edu Windows licence.

His MSFT account says the licence was already activated 2 years ago, which would be when he got his laptop. There should have been no need to use the EDU Licence, as the laptop has Windows OEM.

Is there a way to de-activate the EDU licence, so it can be reused, and re-activate with the OEM Key I assume it's embedded, there is no sticker.

Two OEM licence keys (different Windows versions) on one PC

Hello,
I'm in the process of building another PC and I want to know if it's possible for two versions of Windows to reside next to each other legitimately. I would have windows 7 and 10 as a dual-boot system. So if I buy OEM keys and activate them would one de-activate the other? I know that OEM licence keys are bound to the mobo and are irrevocable. Any advice is greatly appreciated. Thank you.

 

Windows 10 OEM licence and activation

Hello,

I have several questions the licence and activation:

Can you legally buy used (and decactivated) windows 10 OEM licences and use them with a PC different from what it was supplied with?

Lets assume I bought such licence and the activation was successful on such a machine - does it mean I can continue and legally use the OS?

I read that there was a 'system builder' clause when using OEM licences that lets you transfer said licences to different machies if you take the OEM responsibility on yourself.

If it's not possible with windows 10 OEM is it possible with any other OEM version of windows such as windows 7 or 8?

Thanks,

 

Windows 10 OEM Licence

We recently purchased machines with came with Windows 10 OEM licences and had others upgraded from Windows 8.1 to Windows 10 during the free upgrade period.

Question - Can we use the OEM versions in a business or will we need to upgrade those licences ?

Thanks
