Well, depends on what you need to restart.

If it’s just a service or two, then it’s pretty quick.

Obviously you need to know, what you’re doing.
And I think that’s pretty hard with windows, because it never tells you, what it’s actually doing during an update.

With Linux it’s much more transparent and often the restart of a service is just part of my update routine.
No need to close and save all my open stuff, and reboot. Just restart the few services that got an update and that’s pretty much it.

So, really depends on the update, the transparency of it and also the personal insight/skill
