Windows 7 - No right-click in Windows 7 with macbook pro

I got a macbook pro from work with Windows 7 and some mac OSX operating system dual booted on it.

I am unable to figure out how to get my right-click back in Windows 7, and of course, that's the OS I predominantly use. It's driving me nuts.

Also, not sure if anyone else has ever heard of this problem. My macbook pro headphone jack has a red sensor light that won't turn off, and unfortunately it disables the speakers. I thought the sensor was broken as I tried some tricks I read on other forums (using a matchstick, cleaning the sensor with rubbing alcohol, etc.) but it was an epic fail. However, I noticed that whenever I boot up on the mac OS, the sensor turns off and the speakers are enabled. Now I'm wondering if there's a setting in Windows 7 I could change that would fix it.

To be honest, not having sound on one OS isn't a big deal, just an annoyance really.

If anyone has an ideas, I'd appreciate it.
Thnx.
