This keeps Windows stable while successfully preventing forced updates like Windows 11 25H2.</p> <h3> Key Features </h3> <ul> <li>Blocks <code>wuauserv</code> and <code>UsoSvc</code> instantly.</li> <li>0% CPU usage / Lightweight tray app.</li> <li>No registry hacks or service corruption.</li> <li>Works even during forced update phases.</li> </ul> <p>Check out the full source and documentation on GitHub:<br> <a href="https://github.com/type2Rhyme/UpdateBlockerProTray" rel="noopener noreferrer">https://github.com/type2Rhyme/UpdateBlockerProTray</a></p> <p>Happy blocking!</p> windows showdev tools utility
