Yes but there's "should" not "is" or "must". Important is how the ntvdm.exe is compiled. I expect they used MSVC which should use 32bit int.

Here's interesting discussion about this theme:

One post says:

C enums are int-sized. C++ enums are of the smallest size that can represent all the values the enum can take.
