Is there any controindication on using Registry Cleaners SW (CCleaner or Registry Mechanic) with NIS 2009 ? I know that many users are against these applications, but so far, I never had problems and I love the idea to eliminate useless registry entries. I red somewhere that Registry Cleaners can somehow damage NIS 2009 so I don’t run them anymore since I installed NIS 2009. What is you opinion or experience. Thanks in advance.
