Has anyone ever experienced Win 11 DND mysteriously turning itself back on, regardless of whether persona management (ProU for us) is enabled or even blown away?

Single Session MCS Pooled Random 23H2 Win11

FWIW, I've tried these with no luck.

```$registryPath = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Notifications\Settings"

New-ItemProperty -Path $registryPath -Name "PresentationQuietHours" -Value 0 -PropertyType DWORD -Force
New-ItemProperty -Path $registryPath -Name "GameModeQuietHours" -Value 0 -PropertyType DWORD -Force
New-ItemProperty -Path $registryPath -Name "FullScreenQuietHours" -Value 0 -PropertyType DWORD -Force
New-ItemProperty -Path $registryPath -Name "UpdateQuietHours" -Value 0 -PropertyType DWORD -Force```

Have you tried this?

```reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\QuietHours" /v "Enabled" /t REG_DWORD /d 0 /f```

Will try it, thanks, we were putting that under MS/Win/CV/Notifications, which is where it was on Win10.  Will try one key up, right on CurrentVersion as you suggest, thanks!

No luck, but it does seem that it is related to QuietHours or more specifically the last checkbox here (wild guess).

The reason I say that is Do Not Disturb appears to auto disable +1 hour into a session.

Odd thing is, the base image has not received a feature update, these are deployed as 23H2 via SCCM, not IPU'd from earlier builds.
