The following sequence of operations generates a general protection fault
(GPF) in the target Windows NT Virtual MS-DOS Machine (VDM) :
- In ControlPanel, double-click the International icon and change the
Keyboard Layout to something other than US (French, German, Spanish, UK,
and so forth).
- Open a Windows NT VDM window.
- Start a 16-bit application, such as edit file.txt.
