The information in this article applies to:

  • Microsoft Win32 Application Programming Interface (API), when used with:

SYMPTOMS

When a 16-bit Windows application is launched from a Microsoft Windows NT, Windows 2000, or Windows XP service or from a 32-bit process that was launched from a service, the Windows application is always launched into its own separate VDM (Virtual DOS Machine). 16-bit applications launched by other 16-bit applications always run in the same VDM.

STATUS

This behavior is by design.
