Upgrade from 17115.1 to 17120.1 done without any issues.
One interesting observation however. Before upgrading, I updated all Store Apps, and after upgrade was complete, Store wanted to upgrade all my Store Apps again. Now I'm not sure if the upgraded build brought back old App versions or that this build has Apps available that are only compatible with 17120.1 and beyond...
I have just installed 17120 but not yet clicked update now, and am just preparing an iso using uupto iso and I noticed the uup donwloads
DIR->ESD: Microsoft.ModernApps.Client.professional
DIR->ESD: Microsoft.ModernApps.Client.All
I do not recollect these before, and I wonder if this is why you observed it seems to download all and the updated them.
It also took a lot longer to get through the initial uuptoiso phase where it lists all esds.
