Under Settings – Extensions ; you get an error that says “This extension is managed and cannot be removed or disabled”

Removing it is pretty straight forward; although not through Google Chrome

• Note the ID of the Extension that you wish to remove; appears as junk alphabets (eg: lmnoplmnopsatlyu)
• Close Google Chrome
• Open Windows Explorer
• Ensure you have access to all hidden files – Organise – Folder and Search Options – View
• Navigated to C:\users\<username>\Appdata\Local\Google Chrome\User Data\Default\Extensions
• Delete the Folder that matched the Extension ID
• Restart Google Chrome
