My system has almost 12Gb of .msp files. At least some of them result result from failed patches that were later successfully installed or superseded by later versions or replacements for the software involved. It is possible to go through and manually search for which ones are registered and delete the copies that are not. But with 12Gb that gets tedious really fast. It would be a nice feature if CCleaner could automate this search and delete process. Or, does someone know a better (and safe)way to do this?
