Removing old OS files after XP install?

[Guest]

I installed XP over an existing Me system and after several months now
everything seems fine. I lost quite a lot of disk space however and would
like to know how to clean up to old OS files saved during the XP install. I
did select to backup the old OS just in case there were problems but I feel
reasonably sure now that I won't need to go back so I'd like to get rid of as
much unneeded stuff as possible. I do the 'Disk Cleanup' and have removed all
but the last Restore point but still have only about 1GB left on a 6GB drive
and I'm sure there is at least another gig or so being wasted.
Any suggestions welcomed.
Thanks!

The Add/Remove app in control panel will let you remove the uninstall files.
