I only know my experience with the systems here at work. Win95B (OEM/OSR2)
and NT 4 systems, looking at the Windows Explorer program. It is possible
that Windows Explorer does not do graphics normally, but highly unlikely.
I have seen the same results on at least three different machines here,
running Win95B, NT4, and 95 (unknown flavor)...
