AFAIK you cannot change CSP/KSP after you have installed CA. However you could make a migration. The process could be as follows: 1. Backup your CA database / Stop Certificate Services. 2. Backup all the configuration (if you used configuration scripts this should not be a problem)
Another way to remove the burn odor from your microwave is to wipe down the interior with a half water-half vinegar solution. Then pour a quarter to a half cup of straight vinegar into a shallow bowl, place it inside the microwave, close the door, and leave it at least overnight.
You can add four or five cloves, too. Put in the microwave and heat on high until the water boils and creates steam. It's the steam that really accelerates the deodorizing. Caution: The water and steam will be extremely hot. Be sure to let the mixture cool completely (at least 15 minutes) before opening the door. Leaving the door open for a while afterward will help circulate the air. You can also try baking soda. Just fill a large bowl with 1 cup of water, 2 tablespoons of baking soda and a drop of vanilla or lemon extract. Place in the microwave and heat on high for two to three minutes. The walls of the microwave will be damp and make it easy to remove stains, and the smell will be gone, too.
