I came across RegCure website, you download their free scan and it cleans up your Windows Registery and finds other errors. I downloaded it and scanned for errors, it found many - but however for Regcure to fix the errors, you need to Register and a pay a fee, $39.90. Is that true? And if it is true why do they call it free scan. I heard CCleaner is good. Which is Better RegCure or CCleaner?
