Since you are running Enterprise, is this computer part of a domain managed by a company/organization? If so, you need to talk to your IT folks. These settings are likely being set by the domain's AD server based on organizational security settings.
If this system is not part of a domain, why are you using the Enterprise version?
It is actually a school laptop but they are not strict whatsoever with the security as we have them at our own risk. I'm the administrator of it and am allowed to change nearly all of the settings. No blocked websites, no needing admin privileges to install something, so i was just curious as to why this would be greyed out.
