The immutable distro doesn't work for Windows most likely due to disk space. As someone who has informally supported a lot of Windows devices in enterprises it was surprising to me how many Windows problems are a result of running out of HD space and how often updates can't happen (the old fashion kind) simply because there isn't enough HD space for the update. I wouldn't be surprised if something like 5% of updates couldn't happen due to this.

Windows does do hotpatching, but there's a lot of things that aren't hotpatchable. Do you really think that Windows is like "naw, we could do zero reboot updates, but prefer not to because we are so dominant in the OS space"? This would be an incredible feature for the enterprise. In fact the enterprise version added a bunch of new hotpatch support just last year, but still requires quarterly updates and only does security updates. You really think that they did all that, but decided to not do the rest because they're comfy?

Again, I haven't seen Linux or Mac solve the problem fully either, nor iPhone or Android. AFAIK even every cloud provider has to do a reboot. Would Google or Amazon or Oracle have figured this out if it was so easy? How is it that there is no actual software engineer in industry that knows how to do this, but everyone on message forums seems to? Why don't these companies just hire people from message forums?
