2008R2 IE 11 Group Policy Preference Proxy Configuration Issues

Question

I've been mulling this problem over for a while and I finally have to accept I can't use IE Maintenance anymore for managing proxy settings.  I've been reading up on how to make Server 2008 R2 work with GPP settings for IE 9 - 11.  Everything I've
read says I need to install the .admx files (link below) or install IE 10+ to get the IE Preferences to show up for 9, 10, and 11.  But when I look at my .admx files in %systemroot%/PolicyDefinitions it has the same exact .admx file that I download
from the Admin Templates.  I can not see the policy preferences for IE 9, 10, or 11 and need these options so I can configure a Proxy server.  How do I go about getting these preferences to become available in Server 2008 R2 SP 1?

Note that I also tried the following to manually add support while testing but it didn't help me:
Open up the policy, and create an IE8 Preference: User Configuration --> Preferences --> Control Panel Settings --> Internet Settings --> New --> Internet Explorer 8 -> Set your proxy settings
Navigate to C:\Windows\SYSVOL\domain\Policies was an easier route, then sort by date for the recently created IE entry.
Navigate to User\Preferences\InternetSettings
Open up the "InternetSettings.xml file, and change the MAX value to something above 10.0.0.0 (I usually put 10.5.0.0). This way, the policy won't trip up later on if IE 11 comes out and doesn't support any of these policies, but at least you'll be safe
until 10.5.0, or until a hotfix is available. "
max="10.5.0.0"

Although seemingly surprising, that's ok - Win7 GPP doesn't know that
IE10 GPP exists at all, so it defaults to whatever the programmer made
the default.

That I cannot confirm - here it displays exactly what is configured.

Cannot confirm, too - that is what I tried with the IE10 GPP for Win7,
and it works. You know about the red/green lines and the F5...F8 thing?

That's a known bug in the proxy settings screen.

Definitely - sorry - wrong. The Server (DC) doesn't know about the
contents of GPP, these are simple XML files the GP Editor writes to sysvol.
In fact, most CSEs store their settings in files on sysvol, and the DC
doesn't care about the contents of these. SOME of them (Wifi, eg) on the
other hand require AD objects, and this objects sometimes require a
specific schema version. But even in this case, the DC OS doesn't matter
- schema updates can be installed on downlevel OS versions, too.
