This machine was purchased with Win10 Home, the predecessor machine had
Win7 Pro (but now has linux) I changed the product code on this machine
for the code from the sticker on the predecessor and it re-activated
with Win10 Pro.



I found that the MS server must recognize the HW.

I had a machine with an activated version of Win10 that I transplanted
into another machine. It needed to be activated for the new H/W.


When I later brought that first machine back into service and installed
Win10, it came up as activated.
