The number of times I've seen Windows 10 break on a Windows update on some machine in a new and interesting way is significantly higher that most Windows OS releases I've seen. Its outperforming Windows Millennium in this metric. Sometimes it also manages to break the user's apps at the same time. At issue seems to be MS ramming updates down people's throats. I'd say there is a benefit in waiting for patches to be tested thoroughly, and scheduling less aggressive restart times. MS needs to release control of this aspect as they clearly don't understand change management. I appreciate updates can be deferred, however I find after a while they apply regardless resulting in unexpected restarts on systems that are expected to always be available.
