Windows 11 24H2 Introduces “No Reboot” Updates Feature with KB5058497 Launch

Understanding the Windows 11 24H2 Hotpatch Update KB5058497

As part of the latest Patch Tuesday rollout on May 13, 2025, Microsoft introduced the Windows 11 24H2 hotpatch update KB5058497. This groundbreaking update, designed exclusively for the Enterprise version, allows for installations without rebooting, reflecting a significant advance in update deployment efficiency. However, it’s important to note that users of Windows 11 Pro and Home editions are currently excluded from this feature, with no timeline provided for a possible future rollout.

What is Hotpatching and Its Benefits

Hotpatching, previously seen in Windows Server environments, minimizes the operational downtime typically associated with updates. This process is a game changer for system administrators, enhancing productivity by enabling the installation of crucial updates without the interruptions caused by rebooting.

How It Works Behind the Scenes

Hotpatching modifies small sections of code in memory while Windows continues to run. Here’s a concise breakdown of the process:

Essential system components remain loaded in memory.
The hotpatch package includes only the corrected code segments and a reference map.
During operation, Windows transfers these pieces to idle memory pages, adjusting running applications to use the updated code.
The updated files are saved to disk, ensuring that changes persist even after a reboot.

This efficient method negates the need for a full system restart, thus dramatically improving update rollouts.

Understanding Update Categories

Despite the tremendous capabilities of hotpatching, full baseline updates, which are comprehensive cumulative updates released quarterly, will still necessitate a system restart. Understanding the distinction between these updates is vital for system management.

Baseline vs. Hotpatch Updates

Quarter	Baseline Update (Requires Restart)	Hotpatch Update (No Restart Required)
1	January	February and March
2	April	May and June
3	July	August and September
4	October	November and December

KB5058497 falls between the May and June updates of 2025, categorizing it within the “no restart” timeframe. It’s critical to recognize that this hotpatch capability is only available to Windows 11 24H2 Enterprise versions and specific Windows Server editions.

Implications and Future Updates

As of now, users running Windows 11 Pro and Home will not experience the convenience of such reboot-free updates. These users will continue to receive the conventional update KB5058411, which, while offering similar fixes, still requires a reboot after installation. Keep an eye on Microsoft’s updates as further announcements regarding hotpatch adoption for pro and home versions could be made.
