It's called "Session 0 Isolation". It used to be, prior to 7 maybe Vista , that services ran in the same Session as the first user to login to the console, Session 0. Since services normally run with elevated privs, it was possible for a malware service to show a UI to the user in the same session. Hence, the rise of Session 0 Isolation. S0I was designed to protect users from potentially bad service and driver processes as well as the other way around, protecting legit services from potentially hazardous user applications.
Your code previously only worked because services and user apps could run in the same Session, under different Stations.
That doesn't happen anymore under 7. Even services tagged as "Allow Interactive" are stuck running under Session 0, completely isolated from Session 1 and above. You can create new processes, specifying the Window Station and Desktop to run the process under, but you can NOT specify the Session to run under. Even if the Station and Desktop id's are identical, each Session maintains its own table of Stations and Desktops. Are you passing the users security token to CreateProcess??
Then you can pass the modified token to CreateProcessAsUser. I have no idea if it's going to work or what else has to be done to get to the user to see the process. In order for a "user" application to be executed from a service, the "Allow to interact Yeah, the only problem with doing that is it's interactive all right, just not on the users Window Station. Under 7, the service will run under WinSta0, but a different WinSta0 than the user sees. The service WinSta0 is still stuck in Session 0, which the user won't see.
It seems I'm just going to have to find another way to do this and that will require some change to the requirements. Basically, with the switch to Windows 7 "you can't get there from here" anymore. Felice Pollano Feb pm. Dave Kreskowiak Feb pm. Felice Pollano Feb am. I seen this question marked as an answer because I have the same problem. Since the reply is signed as an answer, but is not, I think is better to know for anyone else reading the thread.
Kindly Specify is there any other ways to overcome winsta0 from windows xp to windows 7?? Dave Kreskowiak Nov am. You haven't read this entire thread, have you? Thanks dave I have a application which works on windows xp.. I understood what happened.. But i need the solution for that.. I have to call that application.. Dave Kreskowiak Nov pm. You have no choice but to scrap what you have and rewrite so that your service doesn't attempt to do anything with the users station. You'll have to have a separate application that runs on the users desktop and accepts commands from the service over some IPC channel, like a named pipe.
This second application can do whatever you want, like launching other applications because it is running as the user and in the users Desktop. One flaw in the 'correct way'. You have to have the client app running to interact with the desktop. If someone closes the client then your service can no longer tell the user something. And as the service cannot restart the client s0i you are stuck. Everyone seems to assume the control wanted is client to service where as I want service to client.
Then ask for thier response upon some questions to continue processing. I also have the issue where I want a generic service to run in multiple environments. With shell explorer. By the way. The statement about it not being possible to start a client visible app in session 1 from service in session 0 is kind of a lie. Microsoft themselves do it. You you see in action at least once a month EXE in session 1 your logon. Dave Kreskowiak 6-May am.
Actually, it's not a lie. Your service cannot use it. End of story. Trying to force it to do so only makes your code possibly incompatible with future Windows, i. WinXP to Vista and above. Good luck trying to get it to work. Dave Thanks If i made like this how can i use it for Windows XP??
When it works on Windows 7, it'll work on Windows XP. You're just now being forced to do it the correct way instead of a "hack" only supported on XP and lower.
Dave one more thing I need to know.. Dave is completely wrong! Posted May pm Robson Carvalho Joaquim. CHill60 May am. That article is dated and is for Vista. Windows has moved on a bit since then and many of the security holes have been filled in. If you read the entire thread you will find Robson Carvalho Joaquim May pm. Your statement isn't true. I use the CreateProcessAsUser in window 10 and work flawlessly Try yourself and come back here to change your comment. Dave's answer is wrong, just because the question is about starting a process in a user session session 1 and above from a service, not presenting a GUI in session 0.

Alternate solution: "control userpasswords2" On a Windows host, you can reset the Computer Access Code without opening the LogMeIn host interface using the so-called control userpasswords2 method.
Go to the computer that you want to be able to access remotely. Type control userpasswords2 and click OK. Click Reset Password. Type and confirm your new Computer Access Code. Click OK to save your change. On the left panel, open the Users folder and right-click to display the menu.
