Hi. I noticed that my WINDOWS folder contains alot of double dlls(60-70%), and was wondering if there's a SAFE way to remove these. I have the feeling that some serve no purpose(old application left-overs). Folders in question are the SYSTEM 32 folder and other various folders inside WINDOWS. I am running XP-PRO with SP/2. I heard of a tool called ClnSys-any good? Any help would be well taken. Thanks!!!
