.adm template not working

I was playing around with trying to create some custom .adm templates
for group policy, but the settings I'm trying to add do not work. Can
someone explain this behavior to me? For instance...

; Test Group Policy Registry Tweaks
;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
CLASS USER ;;;;;;;;;;;;;;;;;;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; This one shows up as expected

listed under it
