Heads up — Microsoft is rolling out the Windows 11 June 2026 Update (KB5089573) and it comes with an important warning: Secure Boot certificates on many Windows devices are expiring this month. If you haven't updated, some machines may have trouble booting securely. On the brighter side, the update also brings faster local file search and a new Low Latency CPU profile for snappier performance. Patch now and don't wait on this one. 🔐
