One of our computers only has a small amount of HD space left and I'm trying to delete unnecessary files. It uses Windows XP Professional, 256 MB RAM, 5 G HD (the original 20 g HD was replaced), 1200 MhZ celeron processor, runs on a network with DSL. It's a Compaq Presario 5400US desktop PC. I've deleted or uninstalled numerous files, and run batch files to make space available, but there's still too few megabytes left.

It runs AOL 9.0 and AVG anti-virus 8.5 , but I want to see what can be deleted from folder(s). Other files listed in Control Panel:

  • MSXML 4.0 SP2 (three times): KB 927978, 936181, 954430
  • Pure Networks Port Magic
  • Security Update Windows Media Player 9 (2006). (Windows Media Player is never used)
  • Learn2 Player (Uninstall only)

There are many security updates listed. Can I safely delete Windows security updates from 2006? There are many of these security updates from 2008+.
