How to remove Chrome policies?

Solution 1:

Policies in Chrome are in the registry.
Is this your company computer? because if you removed it they will put it back again.
Anyway, delete the following keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google
HKEY_CURRENT_USER\Software\Policies\Google

Solution 2:

i can't understand your problem, the windows registry locations of chrome policies

Windows registry location:

Software\Policies\Chromium\ExtensionInstallWhitelist 
Software\Policies\Chromium\ExtensionInstallSources
