When Cleanup premium notifies me that I have outdated or corrupted drivers and I click in resolve, it shows a screen where it shows a scan for performance issues. The scan just keeps running with increasing count (over 10,000 before I stop it) without showing any additional information. Why is it doing this and what does it mean? What performance issue is it finding? It should show me something useful. It does this on all of my machines, so seems to be by design, but I can find no information about it. Before I consider buying driver updater I want to know what this behavior is for, other than scaring me to buy something I may not need.
