Don't confuse the technology with the legalities. "The license" is a contractual right that you have legally purchased. If Microsoft's piracy-detecting hair-triggers are firing in a situation where you still have a license per the contact - oem licenses are usually "on this PC" or the like, so toggling UEFI alone shouldn't breach the terms - that should be their problem. You're entitled to your license.
