In reply to a post by TinyMongomery:

Hardly worth buying a licence just to evaluate Windows 11.

That is why I put on the bottom, Windows 11 will run without a key. My brother used Windows 10 without one for nearly a year until I got him one while sorting out his computer.

Thanks

I only asked about licencing as I have probably a dozen or so old Windows 7 desktops (think the are Dell) in the barn, we took the opportunity to upgraded the hardware and OS when we moved a few of our outlets to new premises. Didn't know if I could use one of those licences for the proof of concept as the mini pc may be the way forward if I need to upgrade any more .
