Hey Bob
If you are able to find the icons on the 98SE disc, and can view them then you should be able to copy the icons of the disk and into a folder in your local drive. You will then need to change all of the icons in the properties of each folder/file. you may be able to find icons from 98SE to use with XP by searching google as well
Let us know how you get on.
My wife just got a computer with Win XP Fam Edit. She is not satisfied with the Desktop Icons that are available for XP. However, she likes the ones on Windows 98 2nd Edit. Can we download them to XP from win 98 Install disk? Please help. I don't want to have to downgrade her pc. Your friend, Bob
