In the test version of Windows 11, the Hotpatching option has been added.

Microsoft has introduced the "hot patching" option in the test version of Windows 11, which allows you to avoid frequent reboots of the operating system after installing updates.

Hotpatching "fixes the code of running processes directly in RAM without the need for a reboot," as Microsoft explains. This way, users will be able to install certain updates on the fly without having to restart the operating system.

The idea of "hot patching" is not new - it was previously implemented in Windows Server. Now Microsoft is testing this feature for Windows 11 Dev Channel. Thanks to the innovation, users will no longer have to restart the OS after installing each monthly security update.

However, periodic reboots will still be required-about once every three months - to install basic system updates. That is, instead of monthly reboots, their number will be reduced to one per quarter - in January, April, July and October, according to Windows Central.

Critical security updates, new features, or bug fixes can still arrive at any time, out of schedule, and require a system reboot.

According to Windows Central, Microsoft plans to include a "hot patching" option in the consumer version of Windows 11 24H2, which should be released in the second half of this year. This feature will first appear on devices with the x86-64 architecture, and ARM64 support is expected by 2025. It is not yet known which specific versions of Windows 11 will receive "hot patching".
