It's possible to use a camera without the disk or drivers. If your computer has a card reader, you can take the pictures, take out the card, and stick it in the computer's card reader (then just copy them from the card reader drive to the computer's hard drive).
I haven't used any camera software since my Nikon Coolpix 990.
Even without a card reader you can use Internet Explorer to get the pictures off a lot of cameras with a USB cable (and Windows Fax and Scan, or Document Imager [I fogot which one it is])--just let me know if you don't have a card reader built into the computer.
