Microsemi's (Adaptec) maxView Storage Manager Agent software requires the following registry key: HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\StorMan CCleaner offers to delete it during fix. If not excluded, the maxView Agent will fail to run and you cannot manage your Adaptec RAID controllers via the maxView GUI. Perhaps this could be viewed as Adaptec doing something odd rather than a CCleaner bug, but Adaptec is a rather big dog and messing up RAID controller management presents some rather big problems.
