Tried it once more, used the manual method. Removed the indicated strings from both of these and rebooted. Still there. Verified with the Resource Editor app that the strings were indeed gone and my edited files were not replaced.
Hacked these two files so far.
C:\Windows\System32\en-us\user32.dll.mui
C:\Windows\SysWOW64\en-us\user32.dll.mui
Next...?
