HKLM\Software\Policies\Microsoft\Edge
Enable this policy to use roaming profiles on Windows. The settings stored in Microsoft Edge profiles (favorites and preferences) are also saved to a file stored in the Roaming user profile folder (or the location specified by the administrator through the 'RoamingProfileLocation' (Set the roaming profile directory) policy). If you disable this policy or don't configure it, only the regular local profiles are used. The 'SyncDisabled' (Disable synchronization of data using Microsoft sync services) only disables cloud synchronization and has no impact on this policy. See https://go.microsoft.com/fwlink/?linkid=2150058 for more information on using roaming user profiles.
