Description

JwImpersonateLoggedOnUser impersonates the current logged on user (on console) and returns an interface pointer to the token. It's automatically freed and reverted to self if it runs out of scope.

Remarks

This function is intended only for use in services. It impersonates the user working in the active console session and ignores all the other terminal session (like RDP). This function works also on Windows 2000 Workstation.
