What is a one-sentence summary of the following article?
Take care to remove any clips holding the molding in place properly. These clips release many different ways (i.e. pull straight out, remove the middle first, push in from either side, etc.) but damaging them will mean that they have to be replaced. They can range from very cheap, to relatively expensive, and some of them are hard to find. The pinch-weld is an area at the front of the car where different metal components welded together. This provides structure and forms a frame for the windshield. In order to remove the windshield you must cut it away from the pinch-weld. This can be done from inside or outside the vehicle with a cold knife or razor. The urethane is a very strong, but flexible, polymer based adhesive.  If you choose to cut from the outside you might have a problem when the windshield has been placed too close to the pinch-weld. If there is less than 1/8” of urethane then the knife will not have room to drag properly. This causes the glass to break and make a mess. Cutting the windshield out from the inside of the vehicle is the other option.  You can use an extended handle razor knife and cut with a repeated dragging motion.  Many installers also use power cutters which are faster but do more damage to the metal pinch-weld. This should be done with two people. Open the front door on either side of the car and reach one arm in to gently push the glass away from the pinch-weld. Get a hold of the glass from the outside of the car and lift it straight up off of the pinch-weld.

Summary:
Remove any plastic moldings from around the windshield. Analyze the best angle to separate the windshield from the pinch-weld. Cut the urethane. Remove the windshield from the car.
