I have win xp media center, dell laptop duo processor, 1gb ram. use ccleaner, spybot s&d, spyware blaster, and adaware with avg anti virus.
Using 1.34.407 latest version of cc.
Every time I do scan for error and remove any items in cc I get and mmc.exe error after running defrag. I back up registry reinstall and all is fine. I have also ran sfc and reinstalled dll's from xp cd and repaired missing dll's. I have repeated this 3 times to ensure this is the same response and error. After sfc repair all is well, so scan now option is removing a dll related to the mmc.exe error.
