Hi Winterstorm,

there is a collection of several key to disable aditional Ads in Windows 11:

Code:

Windows Registry Editor Version 5.00

; Sync provider notifications in File Explorer
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"ShowSyncProviderNotifications"=dword:00000000

; Get fun facts, tips, tricks, and more on your lock screen
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]
"RotatingLockScreenOverlayEnabled"=dword:00000000
"SubscribedContent-338387Enabled"=dword:00000000

; Show suggested content in Settings app
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]
"SubscribedContent-338393Enabled"=dword:00000000
"SubscribedContent-353694Enabled"=dword:00000000
"SubscribedContent-353696Enabled"=dword:00000000

; Suggest ways to get the most out of Windows and finish setting up this device
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UserProfileEngagement]
"ScoobeSystemSettingEnabled"=dword:00000000

; Show me the Windows welcome experience after updates and occasionally when I sign in to highlight what's new and suggested
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]
"SubscribedContent-310093Enabled"=dword:00000000

; Let apps show me personalized ads by using my advertising ID
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\AdvertisingInfo]
"Enabled"=dword:00000000

; Show Microsoft account-related notifications on Start Menu
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"Start_AccountNotifications"=dword:00000000


Some of them are already present in WinReducer or in other requests, but I believe it to be a good reference.

Best regards,
Markus
