Opera works fine on Windows 10
Opera works just fine with every build of Windows 10 including ALL the beta builds. It's been my alternate browser for a few years and when there were EDGE growing pains, Opera is always there for me.
Version: 53.0.2907.68 - Opera is up to date
Update stream: Stable
System: Windows 10 64-bit
I'm on 1803 build #17134.48 no issues.
