Enhancing Windows 11: The Introduction of Hotpatching
Microsoft has recently rolled out a significant enhancement to Windows 11, drawing inspiration from its server lineage—Windows Hotpatching. This innovative feature is designed to reduce system downtime by enabling crucial security updates to be implemented without requiring system restarts. Initially introduced for x64 devices powered by Intel and AMD processors in Windows 11 version 24H2, Hotpatching is now also accessible for Windows on ARM devices.
The Advantages of Windows Hotpatching
According to Microsoft’s announcement, Hotpatching brings several advantages for Windows 11 users. One of the principal benefits is the immediate application of security updates, eliminating the need for users to wait for a restart. This instantaneous approach significantly narrows the vulnerability window, enabling IT administrators to ensure that all users are equipped with the latest security enhancements. Moreover, Hotpatching greatly reduces the frequency of required system restarts, resulting in minimal downtime and enhanced productivity.
Streamlined Updates and User Control
In addition to its immediate security benefits, Hotpatching allows for the deployment of smaller updates at an accelerated pace. Organizations benefit from enhanced control through tools like Microsoft Intune and Windows Autopatch. Since its inception in April 2025, millions of devices have successfully received Hotpatch updates, and the feedback from users has been overwhelmingly positive, highlighting the feature’s effectiveness.
Scheduling and System Requirements
Microsoft distributes Hotpatch updates on a monthly basis. However, it is important to note that some updates may still necessitate system restarts in particular situations. Approximately every three months, the company issues a baseline update that requires a restart, followed by two months where users can experience uninterrupted updates without forced reboots. This month, users can expect a new baseline update, while the months of August and September will feature no-restart Hotpatch updates. It’s essential to stay informed, as there may still be occasional updates that could require a system restart.
