If your .cab files were installed on your computer, you can save them to a CD.
If they are installed, they might be in the:
C:\Windows\Options\Cabs folder (See Note below)
Sometimes they are in;
C:\win98     or     C:\win98SE
You can search for them by going to Start/Find/Files or Folders and typing in
*.cab
Look in your C:\ drive, and if your drive was partitioned, look any any other fixed hard drive you may have.
If you have a friend with the same Operating System on their computer and the correct Windows installation CD, you could borrow it and copy the CD.
You will need to record your Product Key code from your computer which can be found in the Registry here:
Need to find product keys!Finally, you can contact Microsoft about getting a replacement CD shipped to you.
