Legitimate Digital Entitlements are permanent. They are tied to the motherboard. In contrast, the keys injected by third-party tools are often temporary. KMS activations typically last only 180 days. While the "Upgrade Mate" tool often sets up a renewal task in the Windows Task Scheduler, the "updated" license is inherently unstable. If the tool is removed, or if the renewal task is flagged by antivirus software, the system will eventually revert to an unactivated state.
