That's not precisely how it works USAFRet. Also why does everyone care so much, not like he's "stealing" and even if he was, screw Microsoft.
Yeah, and giving it to your friends isn't precisely how it works either.
VLK does not equal 'unlimited'.
Doesn't mean unlimited but exactly the number it's sold for. Why would MS care who uses it as long as it's payed for ? What could have happened in this case is that somebody may have used same license on another computer or more than licenses is valid for and now it has been rejected.
Right.
But why should the business pay for licenses they are not using?
In any case...it does NOT sound like a VLK.
It was Win 7, he Upgraded to Win 10.
Licenses obtained through Software Assurance are not eligible to do that free Upgrade to 10.
Back to the original question - "Will I Still Have My OS After Swapping Motherboards?"
There are two considerations, Operation and Licensing.
Operation - Changing the motherboard often requires a full reinstall.
Licensing - The Win 10 'license' is a combination of hardware + the original Win 7 license. Change the hardware (motherboard), and now you have a different system. It will almost certainly become deactivated. Not 100%, but probably.
Changing hardware often requires a call to MS to reenable that Win 10 license on the new hardware.
It is completely up to them to say yea or nay.
