What Is The Best Calking To Use Around The Windows On The Outside Of The House. I end u p calking every year because the calking cracks and starts peeling.

What joint space are you caulking? Between what part of the window and whatever?
What have you been using?
Most of the "lifetime" acrylic latex and/or silicone-based (paintable type only for me) caulks last a fairly long time (>5 years) if they are applied correctly (clean, dry surfaces).

You're doing something wrong if it peels after a year.
What are you caulking?

I use the GE 50 year silicone.
Comes in white and clear.
Easy to work with.
Just make sure you tool it, if you know what I mean.
The white stays white.

Several reasons caulk can fail. Wrong product for the material being caulked. Joint surfaces not properly prepared. Joint not properly designed.
Here's a link on joint design. Silicones work well on smooth surfaces. Urethanes work on masonry and wood. Acrylics work on wood if surfaces are cleaned and prepped properly. You can't apply caulk on top of old, failed caulk. Read the label for instructions on joint prep.

Cracking and splitting may be from too much caulk in the joint without an "hour-glass" shape or backer rod for two surface bonding (not three); page 30: http://books.google.com/books?id=fD...resnum=1&ved=0CAgQ6AEwAA#v=onepage&q=&f=false
