Hi. I have been using CCleaner for some time, and it appears to work well.
However, I recently downloaded Uniblue RegistryBooster on the recommendation of a friend.
It "detected" over 400 "serious registry errors" - even though I had just run CCleaner registry cleaner.
Of course, I would then have had to buy the product to "fix" these errors.
Is this just a marketing scam, or does our free CCleaner miss errors that other products find?
