The Main Policy was created many years ago. In the summary report, it clearly shows Internet Explorer Maintenance (Preference Mode)>URLs/Important URLs>Home page URL (set to school web page).
Editing the GPO, the option to change the settings "Internet Explorer Maintenance" under User Configuration\Policies\Windows Settings\ does not appear. Verified it does not exist on any of the other GPOs, as well.
All Browser settings have been moved to another policy, with the exception of this setting because it can't be reset or removed (or seen).
How can I remove this setting altogether from this policy?
Other info if needed: The GP Mgmt is v.188.8.131.52, running on virtual domain controller Windows Server 2008 R2 SP1.
