Wherein the access token is: used to describe the security context of a process or thread, and the information in a token contains an identifier and access privileges of the user account associated with the process or thread. When a user logs in, the system verifies that the user's password passes comparison with information stored in a secure database. If the password is authenticated, the system generates an access token. Each process executing on behalf of the user has a copy of this access token.
Step S102: copying the first access token to obtain a second access token;
specifically, the first access token is copied by using a DuplicateTokenEx () function to obtain a second access token.
For example, the acquired access token is copied as a to a as a master token B using the DuplicateTokenEx () function.
Step S103: acquiring a session identifier of a currently active application program session;
specifically, the SessionID of the current activity is obtained through the wtsgetateconcolsessisionid () function.
Step S104: replacing the session identifier of the second access token with the session identifier of the currently active application program session to generate a third access token;
specifically, the Session ID of the primary token B is replaced with the currently active Session ID acquired in step S103 above by a SetTokenInformation () function.

And S4, acquiring the currently active Session ID through a WTSGetActiveConsolideSession Id () function.
S5. the Session ID of the master token B in step S3 is replaced with the Session ID in step S4 by a SetTokenInformation () function.
S6. finally, the interface program is started by the main token B and createprocessuseser () function in step S5. Therefore, normal communication between the service program and the interface program can be realized.
In this embodiment, the access token a associated with the current process is obtained through the handle of the current process, and then a master token B is copied according to the token a. And then acquiring the current active Session ID, and replacing the acquired Session ID into the main token B. So that the process started by the master token B can be started in the active Session.
