Removing wind sound is tricky since it's basically white noise with frequency components all over the spectrum. But depending on specific environments, it can be more of a "pink" noise that only spreads over a few octaves.
You'd have to look at the frequency spectrum of the wind noise and create a band-pass filter to drop that range a few decibels. You can do this with SoundForge. Apply the filter and hope for the best.
If it's just wind it's not too difficult. If the wind is masking voices or other sounds you want to keep it's a lot more difficult, since you'll lose some of their content in the filtering process. If the wind is changing in volume and pitch AND masking voices there's not a lot you can do.
I've only tried taking out wind on one occasion, and it came down to just experimenting with the filter until I could hear a definite inprovement. But the wind sound was still there in the background. Good luck.

Worked pretty good. Left a bit of a warble in some of the quiter portions, but all in all, did the job.
