Microsoft is testing «hot» patches in Windows 11

Windows 11 users now have the option to install security updates without rebooting their PCs. The Hotpatch feature, which was previously limited to server versions of the OS, is now included in build 24H2 for Enterprise and Education editions. However, it's not yet available for Home and Pro license holders.

Hotpatch works by applying fixes directly to a system’s memory, keeping applications running without interruption. A full reboot is only required once every three months, when the base update package is installed. In the meantime, the system automatically downloads and applies "hot" patches without requiring a restart.

For now, Microsoft has no plans to roll out Hotpatch for Home and Pro editions. ARM-based devices will get support later, but users currently need to manually tweak registry settings. Microsoft promises to streamline this process by 2025. This update is primarily aimed at businesses, where uninterrupted system uptime is crucial. For everyone else, traditional update methods remain the only option — for now.
