: I have a CTX lap top with windows 98. I want to know if I can use the windows 98 cd that came witht my laptop to upgrade my HP pavilion(windows 95) to windows 98, and how do I go about doing it

If the disk is marked upgrade then you can with no problem, however this is illegal.

You can use the disk if you format your HP's drive. This is crap if you don't have all the original disks of the software you have installed and a backup of your files.
