Hello Anselmo,
You are correct - after running Registry Cleaner in its most aggressive mode and fixing all identified errors, I re-run a Quick System Analysis. This analysis consistently shows 100% for PC Health and 98% for Registry Health. Given jv's statement:
jv16 wrote PC Health is calculated from the number of registry errors and unneeded files found from the computer. The Reg Health is calculated only from the registry errors. And the usefulness is simple: to allow the user to see with a one glimpse the overall status of the computer. No need to run many tools and figure out what different numbers mean, just run the quick system analysis and you see it right away.
I would have expected a Registry Health score of 100%. Oh, well - no worries. Thanks for the response.
