It's rather like shouting.
I've yet to find a scanner that meets your requirement for Windows PCs even if I think all the way back to Windows 3.1.
Not to leave you without hope, there's always Linux on some bootable memory key but then again if you can't install a scanner driver then you may not want to research that approach.
