Hi all, i was wondering one thing ... If i use a cleaner (ccleaner, regseeker, jv16powertools, etc ...) and that for whatever reason (bug?) deletes entries in the register that should not, is there risk to change the settings of programs installed in my system? Or the only risk is of missing files? I mean, are there also programs that "interpret" deleting files, like a restoration of default values for its option? Then, if i set automatic defragmentation (or cleaning ..) and simultaneously convert a file, is there the risk that if both programs are trying to access the same time, conversion fails? Thanks in advance!
