There are several software programs that have not been installed on my computer for years. However, I keep finding references to them every now and then -- even after running Ccleaner's Registry Cleaner and Registry Mechanic. Many of them even still show up in the Application section of CCleaner.
Is it safe to find the folders referencing these various programs under the "Software" section in RegEdit and simply delete them? If that's OK, I assume that deleting them will clean up the problem so that they're no longer found. Right?
