In a support document that has since disappeared, Microsoft refers to hot patching, which involves installing updates without restarting the PC. The transfer follows earlier tests in February.

Microsoft hinted at the advent of hot patches in a recent online support document, but it disappeared as quickly as it appeared. The document contained no valuable information other than the title: Hotpatch for Windows (Ge) – 2024.08 B.

Hot patches would be a welcome addition to Windows. With a hot patch, the operating system receives an update without the need for a reboot. The entire update process then runs in the background, which is much less disruptive for users.

Microsoft has been testing hot patches since February. Redmond tested the function in Windows 11 Insider Build 26058 (canary). Microsoft already has a lot of experience with the technology. It is already being actively used in Windows Server and Xbox.

Microsoft hasn’t officially confirmed it yet, but there’s a real chance we can expect hot patching with the Windows 11 24H2 update, which is due out this fall. Hot patching is currently only being developed for traditional x86 machines. ARM systems will have to wait until 2025 to install Windows updates without rebooting.

Not every update will work using the new method. Some will still require a reboot. Monthly security updates are probably an ideal first candidate for the new method to be introduced. In theory, you would only need to reboot your PC after the major quarterly updates in January, April, July and October.

Of course, unexpected updates in between can always require a reboot, for example to close a serious zero-day leak.

The only thing Microsoft doesn’t say in its update is which versions of Windows 11 will support hot patches. Will every version get it? Or will it be reserved for Pro, Enterprise, or Education versions only? Wait for Microsoft to provide more clarity, perhaps through a support article with content that effectively stays online.
