Unable to change Windows Background Display Bitmaps

We have a custom wallpaper on our banking workstation computers.  We change the background periodically - Christmas, New Years, St Pat's, etc.  

The changes are made in this location:  Active Directory>Group Policy Object>Administrative Templates>Desktop>Active Desktop>Active Desktop Wallpaper.  We change the path of the wallpaper to point to: \\UNC\Policies\xxx.bmp (where xxx is the name of the bmp).

This quit working recently.  All user profiles get the StPat'sDay bmp when they hit CTL-ALT-DEL after their system goes into screen saver lock mode.  We cannot change or get rid of the bmp file from displaying in the background.  It seems like the file is locked or set in the users profiles (not roaming profiles).  Would this be caused by a recent Microsoft security update?  Any ideas why we cannot make this change anymore, in the location we've used in the past?

Thanks

I have set the policy in:
User Config > Admin Templates > Desktop > Active Desktop.
Enable Active Desktop = Enabled
Active Desktop Wallpaper = Enabled (Wallpaper Name: C:\wallpaper.jpg,
Style: Stretch)
The wallpaper.jpg file is present on the all the affected machines and
the policy itself works fine as some of the machines accept the
wallpaper.

The permissions on C:\ are set for everyone to have at least read
access.

Check this registry key on the workstations:

HKEY_USERS\.DEFAULT\Control Panel\Desktop\Wallpaper

If the St. Pat's file is there, remove the existing value and leave the key set to nothing.
