No way to delete the Windows key from M/B
If you remove the connection it prevents transferring the license, as mentioned. It needs to stay linked. No need for offline time. The previous PC will have its license turned off. I still have my Windows 7 license from an old HP computer. I upgraded to 8 Pro, then 10, then switched machines and upgraded again to 11 before this one. Used four different Windows versions across three computers. Paid $300 for the original HP and $20 to upgrade to Windows 8 Pro.

No one here offers a perfect solution or complete accuracy. If you buy Windows keys at a retail store, you can move them as you wish—just contact Microsoft to activate them on a new machine if needed. Legally, you must delete the previous setup before installing a fresh copy since you’re only authorized for one version of the software. OEM licenses are provided with the device itself; legally, you can’t transfer the license to another unit, and free upgrades like Windows 10 aren’t transferable because they’re added on top of an existing OEM license. Microsoft won’t assist if they discover such transfers, though some “migratable” activation methods might allow reactivation on a different system after major repairs.
Focusing on your case, determine exactly what kind of activation you’re dealing with—Windows 7 or 10? Modern Windows 10 uses a new digital license model mainly for free upgrades. It ignores how the previous version was set up; as long as the upgrade was approved, the system records the hardware details and permits reactivation of that free OS when activation is requested after a reimage. The digital license is linked to the device, making it non-transferable.
There are reports suggesting that if you log in with a Microsoft account, the license might be registered there and could work on other devices. Digital licenses operate through a separate system, so methods relying on product keys or activation IDs won’t apply. The Microsoft backend remains unclear to me.
