You may want to consider including the PageDefrag utility in your list of registry defragmenters. It was developed by Sysinternals which was bought up by Microsoft. I have found it to be very useful. http://technet.microsoft.com/en-us/sysinte...s/bb897426.aspx

Thanks, I had already read your posts and found them very useful. I agree before I do anything with the registry that I need to know more, but I am getting tired of nursing Windows and having to become an IT professional to get it to keep running. Anyway, I have read where they may be no real performance gains by tweaking the registry anyway.

I am new to using CCleaner and want to clean out some of the junk in my registry, but I want to do it in steps. So, I am wondering whether it is possible to classify the registry integrity tests that CC uses from the least likely to damage, to the most likely to damage. Damage is probably not the right term, but you know what I mean (I hope). Given the list of registry problems that are listed in the check boxes on the left of the registry window in CC, how would you rank them from least sensitive to most, i.e. is deleting a missing shared DLL potentially more hazardous than deleting an Installer? I am thinking start menu ordering may be the least, but I know nothing about editing the registry. Thanks
