Background
Since some months already Windows 10 starts the quiet hours mode over and over again automatically. I mostly recognize it when using Telegram and no notifications are arriving.
I then check the notification center icon and in most cases there is no icon, which indicates the quiet hours mode being active. In other cases sometimes the indicator is showing up. I always need to disable it manually after it happens.
Question
Is there any way to check what activates the quiet hours (something like logging accesses to the registry key), or maybe even a way to completely disable quiet hours forever?
Additional info
Edition: Windows 10 Pro
Version: 1709
Build: 16299.125
I also use the automatic night mode for reduced blue light, if that matters.
