      Hello,

      i found a very weird effect when f.lux is running, even when it is in disabled mode. Procmon by Sysinternals shows that explorer.exe constantly reads the registry keys and subkeys
      HKLM\Software\Microsoft\Windows\CurrentVersion\RetailDemo\OobeWrite
      HKLM\OSDATA\Microsoft\Windows\CurrentVersion\RetailDemo\OobeWrite (doesn't even exist).

      This happens every second precisely and stops if f.lux is exited, so there is definitely a link between explorer.exe and flux.exe in this case. Is there something happening every second in f.lux, like a timed function call?

        @Girofox123 thank you - it looks like the Windows API (called "SHQueryUserNotificationState") which tells us if it is a good time to notify someone actually writes to the registry, so we have stopped doing it so much (v4.131 should have the fix). There may still be a way to trigger this in the future, but it will be rare.
