I see a lot of angry posts like this, but fail to understand how it's reflected in reality in 2019—I agree that Windows 10 was a little messy at launch, but it's come a long way from where many of these complaints seem to stem from.

1. Prohibit OEM partners from shipping Windows 10-based PCs booting from a mechanical hard disk (yes even "SSHD"). Vendors can add a mechanical hard disk but may not boot from it.
2. By default, no automatic reboot without manual consent especially for consumers.
Long term, look very hard into what kind of update requires a reboot and why. Be willing to break compatibility where required.
