Windows Hotpatch comes to client version of Windows

Good news for Windows users, and for once there’s not a hint of sarcasm here: Microsoft has started rolling out Windows Hotpatch to the client versions of Windows. This feature, which comes from the server versions of Windows, allows the operating system to install patches to in-memory processes, removing the need for a number of restarts. Obviously, this is hugely beneficial for users, as they won’t have to deal with constant reboots whenever a new bunch of Windows updates are pushed.

There are some limitations and other things you should know. First, the way the system works is that every quarter, installations with Hotpatch enabled will receive a quarterly baseline update that requires a reboot, followed by two months of hotpatches which do not require a reboot. Hotpatches can only be security updates; new features and enhancements are rolled up into the quarterly baseline updates. In other words, while this will not completely eliminate reboots, it will cut the number of reboots per year down from twelve to just four, which is substantial, and very welcome in especially corporate environments.

The biggest limitation, however, is that Windows Hotpatch will only make it to one client version of Windows, Enterprise version 24H2, so users of the Home or Professional version are out of luck for now. On top of that, you’re going to need a Microsoft subscription, use Microsoft Intune, and an Intel/AMD-based system (Hotpatch will come to ARM later). I hope it’ll make its way to Windows 11 Home and Professional, too, because I’m fairly sure quite a few of you using Windows would love to set this up on your own machines.
