Thanks Ed...
I dont understand ... how can i do to differentiate teh owner with GetThreadDesktop, im intrested in this one becauser its easy with application.ThreadId to get the current threadid but the GetThreadDesktop returns a handle to the desktop...
Maybe you can explain it to me a little bit more deeper...

Sorry about my poor english

Given a Process handle, you could use GetUserObjectInformation() or GetUserObjectSecurity() or given a threadID, you could use GetThreadDesktop() to differentiate the owner of a given process.
