A large part of my complaints about Windows Update have come because it can brick your machine, System Restore doesn’t work, and so you’re stuck spending a weekend trying to back up and fix stuff.

When I ran Ubuntu with ZFS on root, I had it so that I every time apt was run, it took a snapshot. This came in handy when my WiFi driver got borked during an update; I was able to restore from a previous point, it took like ten minutes.

Using it for the OS partition is not very well supported right now though (for a consumer), installing etc. works fine, but DISM doesn't support ReFS so adding features generally doesn't work
