This seems like a classic windows update issue. In fairness to Microsoft it is difficult to prevent bugs when there is a huge install base, with a huge range of hardware, with a huge range of users on different mixes of updates and updating at their own. I personally think that’s totally believable.

I’m a little bit sceptical here - yes, managing that is complicated. But it also is Microsofts fault - managing and constructing updates that work even with different versions or update paths is possible. I really struggle to see how an update could even kill the start menu or Explorer.
