I'm migrating a group of users from Windows 7 to Windows 8.1. These users are restricted from changing proxy settings via GPO.
In Windows 7, you can change proxy settings only via de LAN Settings within the IE settings window. However, in Windows 8.1, Microsoft has added the Network>Proxy settings from the PC Settings menu in the Metro interface. So now users can disable the Automatic Proxy Configuration that we have set for them and can navigate freely the internet.
I have been looking at a GPO setting to prevent that from happening and the only way I've seen to do it so far is to block the Control Panel/PC Settings completely, but that will not allow them to change other settings that I need them to be able to do.
Has anyone worked out a solution for this or is there a new GPO setting I haven't found?
I have already tried the suggestion here: http://social.technet.microsoft.com/Forums/windows/en-US/7d420c66-2e89-43d7-b136-baf5f69690f1/locking-down-ie-proxy-settings-under-pc-settingsnetworkproxy-on-windows-81?forum=w8itprosecurity
But that didn't work.
