Removing Outlook

For 24H2 this requires 3 or 4 separate steps:

1. From Components, remove both Outlook apps.

2. From Settings, Tasks (UScheduler) / OutlookUpdate -> Delete

3. From Registry, import this reg file:
Code:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CloudContent]
"DisableCloudOptimizedContent"=dword:00000001

4. The last setting will disable Content Delivery Manager, which also includes Spotlight wallpapers and other news feeds. If you want those features, then apply a revert reg file from Post-Setup (After logon):
Code:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CloudContent]
"DisableCloudOptimizedContent"=dword:00000000
 
I believe Content Delivery Manager can be removed as a component can't it? I may just leave Outlook be.
 
There's a simple reason for each of these steps.

1. If you don't remove both Outlook apps, Windows Update will replace them with the New Outlook app.

2. USO Scheduler has a hidden task to install the latest Outlook, regardless of whether your image has any Outlook apps.

3. Even if you followed Steps 1 & 2, OOBE tries to force the new Outlook on your system. To block this attempt, you will need to temporarily block CloudOptimizedContent, which has the same effect of disabling Content Delivery Manager.

4. After OOBE has completed, there will be no further attempts to install Outlook. Therefore if you like, it's safe to re-enable CDM at this time and allow it to perform the usual tasks.
