Mic Jack on WIndows 7

Ok I have a MacBook Pro. For some reason a genius at apple decided that it would be a good idea to combine the headphone and microphone jack into one jack. So obviously when I go on Windows 7 nothing works. Is there any way to get that microphone jack working on Windows 7? This is REALLY driving me insane and I need to be able to use this jack. I tried a bunch os stuff and nothing works. Thanks in advance.

Have you installed all the proper drivers from your Leopard or Snow Leopard DVD?

Also download and install the Boot Camp 3.1 update as it addresses problems with the mic jack and some others. Note that the update requires that Boot Camp 3.0 be installed first. The update executable must be run from within Windows 7.

Regards.
