Are you aware that MS already sells an operating system that can install patches without rebooting? Are you also aware that Linux can do the same? Why can't a supposedly mature 40 year old operating system do the same? Do you have any concept of the number of man-hours it would save globally? The amount of lost work? The impact on patching compliance and security?

My guess is they don't actually believe they have any competition, and therefore don't care to improve anything that doesn't also improve their bottom line.

every week when I login into my Ubuntu with unattended updates enabled I see this: "system restart required".

the hot patch feature you mentioned is paid

		Not to derail but there are issues with kernel patching. If it does work you start building a very large matrix of various levels of hot patches and then sometimes it just doesn’t.

		On Ubuntu, when this message is shown, most of the updates except the kernel are already applied so you are mostly pretty secure. And you can choose when that will happen. And it’s just a normal reboot. On Windows, IIRC, you are blocked during the whole update process which can take several minutes.
