<p>Microsoft is introducing a new &#8220;hot patch&#8221; system for Windows 11 Enterprise users, allowing installation updates without requiring a reboot. This feature, previously available only on Windows Server and Datacenter versions, is designed to reduce disruptions caused by system restarts.</p>

<p>Enterprise users on Windows 11 version 24H2 must opt-in to use hot patching. Updates will follow a hybrid schedule: quarterly updates in January, April, July, and October will still need a reboot, as they bundle the latest security fixes with new features and improvements. However, during other months, hot patch updates will apply security fixes immediately without interrupting workflow. These updates temporarily modify the system’s memory, ensuring protection until the next reboot applies permanent changes.</p>
<p>This innovation tackles a major pain point for businesses—downtime during updates. Reboots can disrupt critical systems and workflows, especially when devices depend on one another to operate. By enabling instant security updates, hot patching helps IT teams maintain protection while reducing interruptions.</p>
<p>However, there’s a trade-off. If updates are delayed for convenience, systems may remain vulnerable, particularly after Microsoft discloses patched vulnerabilities, giving hackers an opportunity to exploit them.</p>
<p>Hot patching is exclusive to Enterprise users, and Microsoft has not shared plans to make it available for home users.</p>
