So, we know that IE9 was released after Windows Server 2008 R2,
And if you tried to create a GPO preference on Windows 2008 R2 Domain Controller for Internet Explorer you will find options for:
– Internet Explorer 5 and 6
– Internet Explorer 7
– Internet Explorer 8
Lets Open Group Policy Management Console on Windows 2008 R2 domain controller and see:
Start –> Run –> GPMC.MSC –> Expand the nodes and select any group policy –> Right Click and click Edit you will see:
Under User Configuration –> expand Preferences –> Control Panel Settings –> Internet Settings
Right Click in the right pane, and click new to explore available options
And as you see, Internet Explorer 9 is not listed (as you already expected)
Microsoft have a hotfix for this situation, The hotfix will not add “Internet Explorer 9” to the Menu, But it will make “Internet Explorer 8” option applies also to IE9 (without this hotfix, the options will be filtered out, and will not be applied on iE9 users).
Download the hotfix from here, Install on the Windows 2008 R2 domain controller where you configure the group policies, and whenever you need to create a preference for IE9 choose “Internet Explorer 8” from the New menu, and you good to go.
If you are applying Internet Explorer preference on Windows 7 machines, consider installing the below hotfix as well, The hotfix is descried and available for download here:
