I think the suggestion is helpful for me. THX.
And do you know how to use CreateProcessAsUser in service, and show process interface in current desktop?
I have a way what done at XP, but failed on win7. Service can start a process but will be show on session 0.
These two days I did research about this.

THX SAKryukov for your help. Sorry for reply late. I had try a solution that start an APP in service. But there are some problem.
So I will describe my goal clearly.
I had a process that want to start after user select the user to log on(but don't login).If you know that in windows vista we can make a COM dll to control the logon operation inherit from ICredentialProvider. The dll may be invoked by winlogon.exe, and run as system.
But the process I want to start must start as a user who I want to logon. I had try to use CreateProcessAsUser in DLL, but unfortunately, had not realized yet, also CreateProcessWithLogon will return a error (It can be success after login, and started in a test APP).
These is my status now.
Oh, and the "weapons" is very powerful, I can do a lot research.

Thanks a lot. It must be helpful for me. I will try.

Thanks for your response. But how can I stop user's operation, such as CTRL+ALT+DELETE, Or if want to rollback to the LogonUI. I think it may not correspond to my function. And could you provide some useful links about you "weapon"?
THX.
