Worked:: ?
**Short description of error**
Using "bpy.ops.screen.userpref_show()" in a script or add-on button doesn't display the Preference window at all.
I know the button works because I used another command and the command executed fine.
It also doesn't work in script editor either
**Exact steps for others to reproduce the error**
Got command from right-clicking and copying command off of preferences menu.
add "bpy.ops.screen.userpref_show()" to script or operator button
