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

On Windows, IIRC, you are blocked during the whole update process which can take several minutes.
OTOH, I upgraded my parents' PC yesterday, after three months of downtime. It really took at least two hours and four reboots. The machine was screaming and the task manager showed a blue rectangle for CPU load (uninterrupted 100%) and a green one for the disk load (again, uninterrupted 100%) while nothing was usable all the time.
Same process takes <10m in Linux (specifically Debian), and an optional reboot, without any hardware load drama.
Funnily, dynamic updates support installation failed after all the kicking and screaming, and I didn't try. Maybe I'll look into it later.
I'd rather teach my parents to use Linux instead. Updates will be a breeze with 3±2 minutes of total background work without any interruption and 30 seconds of occasional downtime.
What I’m against is tolerating a bad OS design with more capable hardware and allowing Microsoft to worsen the experience. This is a pattern of Microsoft since forever.
Oh, that particular PC has no NVMe support anyway. I don’t know why that M.2 port is SATA only.
Especially when every other major OS can handle this more gracefully. I can version upgrade a fully loaded Debian installation in less than 6 minutes, reboot included, on a SATA disk, for example.
Also, while tangential, Windows providing the worst update experience, and calling Linux a major, mainstream OS superior in some ways feels unbelievable when I look back a decade.
In fact, they already figured out hotpatching and will sell it to you for server 2025.
Off topic, but I'm pretty sure that Ubuntu's livepatching is just kpatch under the hood,
