Yes, I've been using CCleaner for at least 2-3 years and I recommend this application to many of my friends, telling them registry clean-up never gave me any problem. (which is truth!) They dare remove junk files but they think cleaning up registry is problematic. I always assure them telling them my experience.
What I learned today was quite surprising. Kindly fix this as I still like to recommend this to people.
Keep up the good work and all the best~
