Hello,

I have a service running, that is watching a directory. If something 
changes in that directory, my service terminates an app, copies some 
files and starts the previously terminated app again. Unfortunatly, 
after that the app is running under system's account.

Is there a way to start the app like before?

Thanks in advance
Rob'

Look at CreateProcessAsUser() or CreateProcessWithLogonW()

Hi Remy,

thanks for your answer.

I know this fuctions, but I don't know how to get the token of the 
current user. Have you a hint (or better a code snippet) how to do that?

That can be difficult to do from inside a service, especially on XP with 
Fast User Switching enabled, or on systems using Terminal Services (which 
FUS uses internally).  In a nutshell, you would have to locate a running 
process for the desired user (such as the Explorer.exe shell) and extract 
its token via OpenProcessToken().

I suggest you go to http://www.deja.com and search the newsgroup archives. 
This has been discussed in detail many times before.
