At work I have noticed that many of the computers I support have had issues with hard drive fragmentation. Of course these are windows xp machines that have seen heavy use. It is a pain to have to go around to each user and explain how to use Disk Defragmenter MMC to clean up the mess. Thankfully Microsoft has created the Onecare Scanner that preforms a brief anti virus scan, spy ware scan, temp file cleanup, and disk defrag.
The one thing I have noticed is that it works best using internet explorer.
