WAU - Intune deployment Issues

[kajavede]

Hi, to start off, sorry for using AI to summarize all my questions and issues, I wrote a few versions myself but always ended with a scattered and unreadable slop.

I am testing WAU 2.12.0 in an Intune-managed environment.
I deployed the WAU ADMX templates through Intune. I did not configure:

Get Black/White List from external Path
Activate WAU GPO Management [DEPRECATED]

because one is documented as already default and the other is deprecated.
ADMX settings configured
I configured the following settings through ADMX:

Notification Level
Random delay for scheduled task triggers
Updates Interval
Updates at Time
Application GPO Blacklist

What works
The WAU logs show that blacklist and notification settings are being respected.
Example:
Notification Level: Full
WAU uses Black List config
Applications in the blacklist are skipped correctly:
Google Chrome : Skipped upgrade because it is wildcard in the excluded app list
Microsoft OneDrive : Skipped upgrade because it is in the excluded app list
So at least some ADMX configuration is clearly being read and applied.
What does not appear to work
The scheduling-related settings do not seem to affect the scheduled tasks.
I tested both:

Installing WAU through:

winget install Romanitho.Winget-AutoUpdate

Direct MSI installation

In both scenarios only the following scheduled tasks were created:
Winget-AutoUpdate
Winget-AutoUpdate-Notify
Winget-AutoUpdate-UserContext
I never see a:
Winget-AutoUpdate-Policies
task on any test machine.
The Winget-AutoUpdate task is created with the default trigger configuration and does not reflect the ADMX values configured for:

UpdatesAtLogon
UpdatesAtTime
UpdatesInterval
UpdatesTimeDelay

Current workaround
As a workaround I install WAU using your (Romanitho's) winget install script with these parameters:
--scope machine --override "/qn USERCONTEXT=1 UPDATESATLOGON=0 UPDATESATTIME=09:00:00 UPDATESINTERVAL=BiDaily UPDATESATTIMEDELAY=06:00"
This creates the scheduled tasks exactly as expected.
Questions

Is the Winget-AutoUpdate-Policies task expected to be created in the current version?

Is there a supported way to centrally modify scheduling through ADMX after deployment, without reinstalling WAU with adjusted parameters?

Additional question about default exclusions
I also noticed that default_excluded_apps.txt contains the following browser exclusions by default:
Brave.Brave*
Google.Chrome*
Mozilla.Firefox*
Opera.Opera*
This means that a default installation excludes several major browsers from updates.
Is there a supported way to replace or disable the default exclusion list during installation without modifying default_excluded_apps.txt afterward?
Thank you.
