The upcoming Windows 11 update might eliminate the need for a reboot, as “Hot Patching” is said to be introduced soon.

According to a report from Windows Central, Microsoft is in the process of testing an innovative update procedure for Windows 11. This procedure aims to eliminate the need for system reboots when installing security updates through Windows Update. The upcoming feature, known as hot patching, is anticipated to be introduced in Windows 11 24H2 later this year.

Hot patching is not a novel concept for Microsoft, as it has already been utilized in Windows Server operating systems and Xbox consoles. Essentially, hot patching involves dynamically patching the in-memory code of a running process without requiring a restart. Microsoft utilizes Cumulative updates as a foundation to prepare for subsequent security updates, seamlessly integrating them into the operating system without disrupting the running processes. To maintain stability, the baseline is reset with each cumulative update.

Recent developments include the extension of hot patching to non-Azure versions of Windows Server 2022 by Microsoft. This expansion helps clarify the company’s decision to implement this feature in consumer builds of Windows 11.

The new Windows update feature, which allows on-the-fly installations without requiring a reboot, comes with a condition—it activates Virtualization Based Security (VBS). For gamers, this may pose an issue, as VBS is often disabled to optimize system performance, given its known slight impact on speed. Microsoft is presently testing the hot patching feature in the Windows 11 dev channel, specifically with Windows Insiders who have VBS enabled.

The advantage of having more updates without the need for reboots is significant, alleviating the inconvenience of time-consuming Windows updates. Users often experience delays of several minutes during the installation of Windows updates. Hot patching addresses this concern and proves particularly beneficial for users engaged in mission-critical tasks that cannot afford interruptions caused by a system restart.

Windows Central reports that Microsoft aims to incorporate hot patching into standard PCs alongside the 24H2 update. However, there’s a delay in extending support for Arm64 devices, which is expected to be implemented a year later in 2025. Notably, hot patching will be exclusive to security updates. While it remains uncertain if other updates will be adapted for hot patching, the possibility exists if Microsoft identifies a viable implementation method.
