Are you trying to say Windows/macOS won't break if they lose power in the middle of the upgrade process? I remember long time ago (maybe back in the xp/vista days) when my Windows installation broke when we had a power outage during my upgrade. Haven't happened lately, but searching online I can see bunch of people having the same problem with latest Windows versions and macOS as well, requiring a reinstall to fix.
