I am using Vista and XP to run belkin peripheral

ok- i use the same one, no driver needed- you hook it all up then boot the pc's and you hit the scroll lock key two times-then tap the up or down keys once. this will switch between the 2 pc's- this is a decent switch, and i really like it. good luck with it! if you need further assistance reply. but this is simple to make it work, so you should be ok. be well!
