re: Disable end user installation
Easy. Start the policy editor (winkey+r, gpedit.msc), Go into the following key:
Conmupter Configuration -> Administrative Templates -> System -> Device Installation -> Device Installation Restrictions.
Here you will find the various controls to limit end user installation of devices. Only thing third party utilities does here, that the build in tool doesn't is give you a nice gui frontend for entering the restrictions, and thus block you from blocking devices the gui tool doesn't explicitly know about.
Now, does anybody have the usb-id of these pesky photo-frames, so I can type up a policy and let the honourable register hand out to tired BOFHs worldwide?
