Same file on different machine configuartions

Hello, I was wondering if the downloaded updates are specific for the same hardware configuration it was download from? As I understood it this is how Windows updates install hardware driver updates. It would be nice to know if I could use the same file so I don't have to re-download when installing the updates on different machine configuration.
By the way, I'm using Windows 7 Pro. The machines widely varies from AMD Phenom, A-Series, core2duo to current gen i3s.
Thank you and have a nice day.
