it a bug in the Display Enhancement Service (as far as i can tell) in the command prompt Code: sc stop "DisplayEnhancementService" wait a bit and then Code: sc start "DisplayEnhancementService" and try and pray that brightness controls work. If not, keep trying. for me brightness controls do not *at* all (keyboard combo, slider, powershell) until i restart the service.
I tried stopping and restarting the service but still not working Anyway that's what these releases are for, to find and iron out the bugs Let's hope they are more diligent than last years fiasco
I think the next build is 18333. Remember the 17666 from RS5 ? It's funny builds with these numbers - 111 222 333 and more.
