Need drivers

I mistakingly deleted some files, which caused my keyboard to stop working. I read on here that yes they need to be reinstalled. I found out which ones they are but can't find them. It is a fingerprint sensor and a microsoft ISATAP adapter #10. I have a Dell laptop operating Windows Vista. Could someone pls help? onscreen keyboard clicking is rough.
