From: "Frank Haber" 

Right you are.  A bit of web-diving produced the surprising info that
REGEDT32 is the older, and started in the NT3.5 era.  I had no idea.  I'd
been made gunshy by the Win95's Regedit crashing with large registries, and
saving a damaged registry - thus the many replacement registry editors in
the 95/98 era.  For some reason I'd got it in my head that the
"32" meant "newer, superior."  Not true.
