The Internet Explorer Maintenance options in group policy are no longer enabled or supported in IE 10.
Previously we used this for setting the users homepage, publishing a few company defined favorites and the Proxy server / pac file.
In order to facilitate the same / similar functionality you need to use GPP, but this can only be performed on a Windows 8 or Windows Server 2012 so you get the options for IE 9 and 10
Its worth noting that GPP makes use of f5,f6,f7,f8 keys to enable or disable the entire page of preference etc.
F5 activates all the options you see. (Green)
F6 activates only the current selected setting. (Turning just this option green)
F7 Disables only the chosen setting. (red/white)
F8 Disables all the settings. (red/white)
Publishing Internet Explorer 10 Favorites is as easy as editing the User Configuration > Preferences > Windows Settings > Shortcuts
Action: Replace, Target Type: URL, Location: Explorer Favorites
