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.
Immediately wipe out the microwave with a damp cloth or paper towels, and if you have a pool of liquid in the bottom of the microwave, use a handful of paper towels to soak it up so you don't get any on yourself and burn yourself. After you've wiped it all clean, poke your head in and smell the inside of the microwave.
