"I good at removing some but not all bad or outdate reg enties"
It remove many reg errors. Haven't had any problem with it removing something that they shouldn't. It do have a Registry compressor that can reduce the size of old registry files to they don't grow to big.
IT don't remove many entries that are from old softwares that has been delete long ago. Or some corrupt entires that I can't be delete be going int the registry.
