Microsoft IntelliPoint Driver (64-bit)
Full user review
"Windows 7 Pro and ITP 8.0 are the fulfillment of I/O."
I am a middle-road gamer, and use gaming mice besides my Microsoft mouse. ITP 8.0 allows me to set my gaming inputs and keep them , instead of rolling over the settings.
I cna't think of any cons.
I use my desktop computer for a variety of functions, and the software for my Sidewinder X5 mouse (Microsoft) is one of amazing pluses to a multi-functional system.
