Application Security May Not Work After Improper Shutdown

You can use Application Security (Appsec.exe) to limit which programs can be run by users on a Terminal Server. A default list of programs is included to allow users to successfully log on to the server. You can add other programs to the list to restrict user activity. After an improper system shutdown, this list may not be read correctly from the registry and memory may contain an incomplete list of programs. Therefore, users who could log on or run certain programs earlier may not be able to because the list is incomplete.
