I want to start a process when user select a account to login at LogonUI.
I had tried to create it in LogonProvide.dll with API which normally create a process, such as CreateProcess, but all failed.(LogonProvide.dll is called winlogon.exe and run as system account)
Is there any way to solve this problem.

You can place the application to run in Registry using the key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

I have my "secret weapon" I use to learn all I need about auto-start processes: Sysinternals AuroRuns application. Go to Sysinternals Web site: http://technet.microsoft.com/en-us/sysinternals[^], download Sysinternals Suite: http://technet.microsoft.com/en-us/sysinternals/bb842062[^], unpack and run AutoRuns.exe. Read help, browse auto-run categories and items — you will find out what is called from where and how you can add your application to it.

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.

Sergey Alexandrovich Kryukov 12-Apr-11 10:58am

As to the "weapon", the only two links in my Answer are about it. Sysinternals was acquired my Microsoft, so it is at Microsoft site now. Even if it does not help you right now, the Sysinternals Suite is a must-have collection of all kinds of free system utilities. Some source code is also available; I've leaned a lot from it.

Yoour follow-up question looks new to me (about Ctlr+Alt+Delete), so could you describe the scenario you want in detail, and the purpose if it? I would think about it, sounds interesting.

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.

Sergey Alexandrovich Kryukov 15-Apr-11 4:20am

You will certainly need to do a serious research, not sure if you can succeed. At this moment, I have no idea how to help it, frankly; sorry.
May I ask you, our of curiosity, what's the ultimate goal of all this activity?

Change the user name. (:
Ultimate goal is that the process will do a operation register user information to system.
If want to let the operation success and correct, process need to run as the user who you want to register. And the process is run when windows logon, it may the most hard crux.

It's a nice set of tools, my 5 :)

Sergey Alexandrovich Kryukov 12-Apr-11 18:29pm

Thank you, Espen.
Yes, it is, of the must-have class, for those who wish to support a neat performing system.

Solution 2

This could help you:

Start Your Windows Programs From An NT Service[^]

It is an article from Xiangyang Liu[^] that will allow you to start your application as if it was a service.

Easy to use and it can work for you.

Regarding the CTRL+ALT+DELETE, you should look at GINA.DLL (if you are using a prior to 7 windows version).

In windows 7 I don't know how to change it's behavior.

HTH!

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

Sergey Alexandrovich Kryukov 12-Apr-11 11:29am

Unfortunately that's not it. The Service is started before logging and and keeps running while people log in and out.

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.
