I created a user preference to show file extensions, using the registry.
The registry shows the setting is correctly configured -- HideFileExt = 1, but after running gpupdate /force, Windows Explorer does not show the file extensions, nor does it show in the view options.
I do have the registry setting running in the user's context, and item-level targeting for now to a specific computer group.
This is just one of several registry preferences that appears to be getting set, I can see the registry entry in regedit, but not applying or showing itself to apply.
Why would this happen??
