Consider the following scenario:
The Windows shell starts the legacy .cpl file. However, the legacy .cpl file requires the highestAvailable run level. Therefore, the Windows shell uses the user token to determine whether the Windows shell starts the .cpl file. The Windows shell does this by using the asInvoker run level or by using the requireAdministrator run level. If the user has a filtered token, the Windows shell starts the .cpl file by using the requireAdministrator run level. If the user does not have a filtered token, the Windows shell starts the .cpl file by using the asInvoker run level.
This problem occurs when you use a non-administrative user account that has a filtered token. In this situation, the Windows shell starts the .cpl file by using the requireAdministrator run level. Therefore, you are prompted to type your administrative credentials.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Vista Service Pack 1.
When an application is marked with the asInvoker run level, the application takes no action. The process inherits the process token of the parent process that created it.
When an application is marked with the requireAdministrator run level, the process must be created by a user token that is a member of the administrator group. If the user who tries to create this process is not an administrator, the user is prompted to type the administrative credentials.
When an application is marked with the highestAvailable run level, the application indicates that if a user has a linked token. Then, the application runs with the higher-privileged token. The highestAvailable run level is generally used for applications that have a user interface that is designed for the Users and Administrators groups. When an application is marked with the highestAvailable run level, the application obtains the full user rights of the user. Users in the Backup Operators group and in the Network Operators group have a linked token and are prompted to type their administrative credentials. Additionally, the dialog box that these users receive has their user tile and the tiles of the members of the administrators group.
