Some registry items come back or not cleaned?
After cleaning and repairs why some registry items still appear on re-scan?

After cleaning the Registry, the first thing many people do is to run analysis again to see if it's really clean. In some cases, you may see some new Registry entries appear in the second analysis. This is nothing to worry about. Removing unneeded Registry entries, can sometimes uncover other entries that can also be removed. All you need to do is run Clean again and these will be removed. If you find some registry entries that are not removed even after a second clean then this is almost certainly because the entry has been locked by the OS. In this case, it is best left alone.

If these are locked files we suggest you to "Ignore" these files on future scans. You will be prompted to add these locked files to the ignore list during cleaning and repair.
