  • Above list is ok but next time add QuickGenie also. I personally use this registry cleaner from past few month and its really working very nice

    • windows 10 has deleted ccleaner twice. I’m a paid member to ccleaner. So not sure why they have not fixed this problem; for they have known for years; about the complaints. I will not use ccleaner again… since they can never seem to find my email; thus forcing me to buy it again. Fck them and the horse they rode in on (called profit and judas).
