the price of the registry cleaner program doesn't matter but if i can get it cheaper don't hesitate to type it down.okay.

for anyone that has good reasons to get the registry cleaner they tell me to get and have good info about the program and if it is a registry cleaner program that doesn't mess with my computer's registry but only cleans invalid registry entries.
