Maybe Windows Should Warn Users When an Update Is Going to Take 45 Minutes?

Windows usually only takes a couple minutes to do an update. Today I rebooted my machine because it was acting up and now I'm sitting here waiting for it to update (20 minutes in and I'm at 26%). I'm imagining the millions of hours of lost productivity because Microsoft doesn't consider warning users that an update will be particularly long, nor does it allow them to restart without updating.

This kind of user-hostile design constantly reminds me that I don't control my PC -- Microsoft does.
