By whom? I would think that unless HDPMI (or any other DOS extender) emulates Windows completely, then HDPMI clients have a need to know whether they are actually running under Windows (version whatever) or not?

I don't think so because PQMagic 4 also thinks it's running under Windows when HDPMI32.EXE is running. (It just crashes if only HDPMI16 is running). Anyway, here is my Windows detection code:
ClearRealRegs(Regs); { Are we running in a Windows DOS box? } Regs.AX := $160A; { DOS Multiplex - Get Windows Version } if Intr($2F, Regs) = 0 then WinVersion := Regs.BX; { Win95 = $0395 }
Notes:

1. The return value of the Intr function is the value of the AX register as set by the callee.
2. Intr calls real-mode interrupt 2Fh via 31h/0300h, not protected mode int2F.
3. I'm sure you can easily work the rest out.
