Basically the equivalent of taking out the trash, you should feel good about it. :^)

Stable so far on 3 different devices for me.

The first 1903 update made the start menu search annoyingly different. The second made it worse by cancelling all the icons I put on it.

It took 15 minutes to figure out all the favourites icons I was missing

I already don't like the non black task bar and the subtle outline around the search box. 

like microsoft knows how to create a good looking UI anyway, they fragmented everything

I can't find the legacy microphone settings for my usb sound card which let me enable AGC, the new audio settings in the metro panel doesn't show this option anymore
