those are from XP Media or Tablet Edition ,not Vista.
your OEM has put them on HDD, likely that you have no original XP Disk, but
only the files on Harddrive.
Burn them to disk for backup purposes, because the i386 plus the cmpntns
contains all the files needed to reinstall XP.
That Cd will not be bootable, so in case you need also to create the floppy
disks to start the XP setup.
Lookup Microsoft Website, they have the floppies for download.
I guess you have made a Upgrade to Vista - that would explain your question.
If you plan to use vista alone and are lucky with it, have backuped the
folders and all then you can delete them.
Like I said, in Vista there are no such foldernames.SO Vista wont miss them
