Hi! I am a new user and I have a few questions. I saw where you stated to be careful of what you select to be deleted because it is gone for good. Well there were two things that were not checked when I brought up my Registry cleaner so I could start scanning. One was System Services and the other was Filter Entries. Do I select them or leave them blank. I just want to make sure I am picking the correct things and am not messing anything up. So if you can please help me to find where I can learn about what section does what like with the system services and be able to pick the correct ones. Thanks so much for your help.
