Internet Explorer Security Level - High Only

Came across Internet Explorer Security option only has High level available. There's no other level available such as Medium, Medium-High. Even the Custom Level doesn't help. This is because "Internet Explorer Enhanced Security Configuration" has been enabled. Follow this to turn it off :

1. Close all instances of Internet Explorer.
2. Click Start, point to Administrative Tools, and then click Server Manager.
3. If a User Account Control dialog box appears, click Continue.
4. Under Security Summary, click Configure IE ESC.
5. Under Administrators, click OFF.
6. Under Users, click OFF.
7. Click OK.
