NTREGOPT is used on a loose
(if I remember!) monthly basis to optimise my registry. This comes with the rather excellent registry back up tool
ERUNT. I have not yet used ERUNT in anger on my 64 bit WIN 7 system but I have used it on my old XP machine. I'm assuming all would be well.
(It does back up my registry, but as I've said, I've not put it back as a necessity yet!).
HandiCapsLock neuters the Caps Lock key. When running, to enable Caps Lock you need to do a double tap. Do be aware though that if
(like me) you add it to your Startup folder, your AV may complain. ESET AV does, but I just add it to its Exclusions list. Never had a problem in the last 3 or 4 years I've used it.
