== IsUserAnAdmin() function ==
Determines whether the currently logged on user is a member of the Administrator's group.
----
> There are times when a program needs to perform an operation that requires the current user to have administrative privileges. This function uses a Shell32 API call to query as to whether the user is an administrator, returning 1 for true and 0 for false.

Edited to add that the minimum OS for this API function is Windows 2000. It won't work on versions before that. [[user:Alyce]]
