This software startup context
Various tabs show information about this software context startup:
  • [ User ] tab:
    Allows to detect a user context change ("impersonation").
  • [ Environment ] tab:
    Shows the received environment.
  • [ Startup ] tab:
    • This software name and location (the exe name is also displayed on its title bar).
    • The arguments it received
    • Its current path
    • Its base priority
    • Its startup time
    • Its parents processes stack
      • If this software was launched automatically by means of the task scheduler, one of its parents processes is taskeng.exe.
      • If this software was launched automatically by means of a shortcut on the Program/Start menu, by means of a registry machine Run key, or by means of a registry user Run key, one of its parents processes is userinit.exe.
        If this software automatic startup is too much delayed, the parent process stack contains explore.exe only. This occurs for instance when the user session is the first one since the system started, or on Windows 8 / 2012, when the user opened his session starting a software instead of displaying the desktop. Apparently, this anomaly comes from Windows: when this problem occurs SysInternals Process Explorer External Link (Microsoft) gives the same information.
Monitoring another software startup context
If you want to know how and when another software was launched:
  • Rename the software to be monitored so it is not started
  • Copy this software to the software to be monitored folder
  • Rename this software to give it the software to be monitored name
You could need to do that when writing a software that launches another process, when writing a command file, or when searching how and when a suspected malware software is started.
Controlling this software return value
Click on [ Return Value ] tab.
You can set the value this software will return on termination. Default value is 0.
This can be useful when testing a command file (.cmd / .bat) that processes the ERRORLEVEL environment variable.
