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.
Lemon, lime and orange juice are natural odor-busters and will not only eliminate the burned-popcorn smell, but will fill the kitchen with a clean, citrus scent. Just combine cup of juice (or chop up a half of any of the above citrus) with cup of water in a 4-cup or larger microwave-safe container.
