I found out that if I enable Protected Mode in IE 9, the Browser runs very slow and freezing up sometimes. I deleted all cookies, histories, and other in Internet Option | Delete but it did not help.
As soon as I disable Protected Mode in Internet Option | Security | Internet, IE 9 is running much faster. I will need Protected Mode enable for Internet browsing, how do I make IE 9 runs faster with Protected Mode on? Also, I don't see the Settings in domain GPO! Please help, thanks.
