|I suggest it's generally wise(r) to avoid running alleged registry cleaners/fixers etc. - unless you really problems and hope they may help resolve them. Frequently folks use such utils and end up with problems they didn't know they had - such problems often being introduced, or "imagined" by the utils themselves...|
That olde maxim:
"If it ain't broke... don't fix it...
is useful to remember when thinking about using these utils.
