CCleaner is good but

After running CCleaner I run System Mechanic to find junk files.SM finds up to an extra 4.5 meg of extra junk to delete so what is CCleaner missing as I prefer CC for it's speed.

And maybe CC could wipe most of the dbx files,selectable, just by automated deletion of such as outlook will create new ones at startup.

System Mechanic isn't the best software. I recall using it about a year ago and it found many false positives in registry, and deleted some "temp" files that were needed.

System Mechanic isn't the best software.

I completely agree, however I'll go one step further and say it's an expensive and dangerous POS! About three years ago I tried it on my old Win98 system and was shocked that it reduced the registry from approximately 6 MB to 1.5 MB, it literally killed the registry. Good thing for MS-DOS and being able to restore a registry backup.

regedit.exe can do that too [but regedit.exe nor System Mechanic is actually causing the problem; it's just bringing it to your attention]. If your registry contains binary mayhem (garbage characters where they shouldn't be), even regedit.exe will truncate it to 1 MB or less. I've had this happen right before my eyes. :)

I'd have to agree with the objections made here concerning System Mechanic. I was glad that I had a clean clone available on another box to restore the partition it damaged when I tried the evaluation version. I've not had any difficulty whatsoever in that way with CCleaner.
