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.
For a scorched smell: wipe inside of the microwave with a heavy dose of white vinegar. Let it set for a couple of minutes. Rinse with water. Then, bring two cups white vinegar to a boil in the microwave. Boil for about 3-5 minutes. (Do not let the vinegar boil dry.) Repeat a second time if needed.
