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.
Of couse, if at any point the smell and stains have been removed to your satisfaction, you do not have to continue to the next steps. Fill a bowl with 1/2 cup water and 1 tablespoon white vinegar. Microwave it for 4-5 minutes and leave it with the door shut for 10-15 minutes. Steam will loosen smell-causing detritus stuck to the walls. Vinegar absorbs odors, even stubborn ones like burnt popcorn smell. After the waiting period, remove the bowl and wipe the inside of the microwave down with a paper towel.
