Seems like good ol’ Billy decided to charge for a new Microsoft Windows license if you decide to change your motherboard. Apparently, thats the “one base component “left standing” that would still define that original PC.” So change your motherboard, you will be considered having a new PC. Thus the extra charges for a new license.
So to the many hobbyists that build PCs either for a living or leisure, you are now likely to think twice, or else switch to Linux.
For me, its Apple for my next desktop, since now they have the Intel chips
