I am currently using Registry Mechanic as my registry cleaner, and it expires in a week. I've Googled and came up with several other cleaners that make RC look a little less than stellar. Not that I've been unhappy with RC, but I was just wondering if it's best for me. I downloaded five others' evaluation copies and ran them and came up with a vast difference in results. Max Secure found 1650 errors, ASO found 123, XP Repair Pro found 923, Registry Patrol found 74, Registry Mechanic found 5, and XP Medic would not even run at all. It's rather confusing as to which program is truthful and will cause less havoc by "repairing" the bad entries. That's why I've come to the good members here, hat in hand. I'm asking for your opinions and suggestions on the best tool, whether it's one of the above mentioned ones or another. Thanks in advance for the help and recommendations.
