I need a batch file to search and delete registry subkeys

I want to search HKLM\Software\Microsoft\Windows NT\ProfileList and delete any subkeys that end in ".bak". I can only come up with this much of it:

for /F %%a in ('reg query HKLM\Software\Microsoft\Windows NT\ProfileList') DO <something something if ends in .bak> reg delete %%a

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this; it's in test mode and will only echo the "reg delete" commands it would normally run. Remove the uppercase ECHO in line 6 to run it for real.
@echo off
set ProfileKey=HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList
for /f "tokens=7 delims=\" %%a in ('reg.exe query "%ProfileKey%" ^| find /i ".bak"') do (
	echo Deleting subkey '%%a' ...
	ECHO reg.exe delete "%ProfileKey%\%%a" /f
