There also is mention of "Win32 virtual console", the +vtp feature.
This is currently enabled for all MS-Windows non-GUI versions, thus it
doesn't appear to have an effect on how Vim works. The feature itself
is useful to distinguish from an old Vim version that didn't support
this.

A problem related to this is that Vim was originally made for the
console, not for a generic terminal like on Unix. In the code there are
calls to is_term_win32() and different behavior when it returns true.
That is when 'term' is set to "win32". And it is set to that value in a
few places, some may not be correct. E.g. near the end of
did_set_string_option():

#if defined(FEAT_VTP) && defined(FEAT_TERMGUICOLORS)
if (args.os_did_swaptcap)
{
set_termname((char_u *)"win32");
init_highlight(TRUE, FALSE);
}
