If you rely on a third-party alarm app on your phone to wake you up, there's a big tweak coming in the Windows 10 Creators Update that should make working around the "Quiet Hours" setting much easier. As confirmed on the Windows developer Uservoice, third-party alarm apps will be able to break through Quiet Hours in the Creators Update, meaning you don't have to worry about your alarm not going off if you use something other than Microsoft's built-in alarm.
Windows Insiders will be able to test this feature out on the Fast ring in an upcoming build. From the Uservoice post:
We just enabled this in the next Insider fast-ring flight of the Creators Update! All third-party alarm apps will break through quiet hours now, just like the first-party alarm app! (Build 14972 or newer).
This is a small, but convenient change that should come as good news for those who depend apps like Realarm to wake up in the morning, but also want to take full advantage of Quiet Hours. Of course, there are a lot of much bigger updates coming along in the Creators Update that are worth checking out as well.
Thanks to Adam and Paul for the tips!
