Disable Microsoft suggestions on Windows 10

On my start menu I have some unwanted suggestions/ads, to disable them with the GUI go to windows settings and search for :

• in english Show suggestions occasionally in Start
• in french Afficher occasionnellement des suggestions dans le menu Démarrer

and disabled it !

But I am curious and I wanted to know where this setting was stored :) In general this kinds of stuff are in the windows registry, but it’s big.

• Open regedit
• Select HKEY_CURRENT_USER
• File / Export in a “before.reg” file
• Change the setting
• Export again the HKEY_CURRENT_USER in a “after.reg” file
• Compare the files

And the key is …

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]
"SubscribedContent-338388Enabled"=dword:00000000

… and you have some other keys in the folder [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]

Here is the list that I have changed from 1 to 0

DisableContentDelivery.reg

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]
"OemPreInstalledAppsEnabled"=dword:00000000
"PreInstalledAppsEnabled"=dword:00000000
"SilentInstalledAppsEnabled"=dword:00000000
"SoftLandingEnabled"=dword:00000000
"SystemPaneSuggestionsEnabled"=dword:00000000
"ContentDeliveryAllowed"=dword:00000000
"SubscribedContent-338389Enabled"=dword:00000000
"SubscribedContent-338388Enabled"=dword:00000000
"PreInstalledAppsEverEnabled"=dword:00000000

I just left the RotatingLockScreenEnabled and RotatingLockScreenOverlayEnabled because I like it :)
