What happens if you format your PC or switch to a new one? (lifetime license)

These Microsoft licenses have a lifetime validity: they are not a subscription service and do not require periodic renewals for a fee. When you purchase one of our Operating Systems, you will own it forever with no additional future costs, and you will be able to enjoy the advantages of having a genuine Microsoft license you can use on your computer or device, even after formatting or migrating to a different one. You can reuse it forever, bearing in mind that it is valid for one device only, and must be therefore deactivated on any previous devices before reactivating on a new device.
