Specifies that Google Update should roll installations of Google Earth Plugin back if the client has a higher version than that available.
If this policy is not configured or is disabled, installs that have a version higher than that available will be left as-is. This could be the case if "Target channel override" is set to a Channel with a lower version, if "Target version prefix override" matches a lower version on the Channel, or if a user had installed a higher version.
If this policy is enabled, installs that have a version higher than that available will be downgraded to the highest available version, respecting any configured target Channel and target version.
This policy is meant to serve as temporary measure when Enterprise Administrators need to downgrade for business reasons. To ensure users are protected by the latest security updates, the most recent version should be used. When versions are downgraded to older versions, there could be incompatibilities.
This policy is available only on Windows instances that are joined to a Microsoft® Active Directory® domain.
