Solution
  1. Open Registry Editor, navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
  2. Select  Chrome, on the right side, see the ExtensionSettings key.
  3. If the Web Filter extension is forced installed (can be via EMS or GPO), it will have below similar value:


{"mbdegapampkgaclohepfibppdhongjgh":{"installation_mode":"force_installed","update_url":"https://clients2.google.com/service/update2/crx"}}

  1. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge.
  2. For Edge, the ExtensionSettings key will have below similar value:


{"ckhgbbanigpkebahlfehgaegmepacdeo"{"installation_mode":"force_installed","update_url":"https://edge.microsoft.com/extensionwebstorebase/v1/crx"}}

 

  1. If the above registries exist, the WF extension may be force-installed by GPO. Open a Windows Command prompt, run below command:


GPRESULT /Z >"%USERPROFILE%\Desktop\rsop.txt"

 

  1. Open the rsop.txt in the Desktop to identify any GPO being pushed that may result in this force installation.
  2. If there is no GPO detected (example below), check with other third-party endpoint management tool, for example Intune, and look for below extension ID in the configuration:

mbdegapampkgaclohepfibppdhongjgh --> Chrome
ckhgbbanigpkebahlfehgaegmepacdeo --> Edge

 

  1. If this extension ID appears anywhere in the third-party tool, proceed to remove or disable it:
