问题 I have cross-compiled a 32-bit analog clock made in ArithmeticExpressionCompiler from Linux to DOS using the GNU Assembler. When run under FreeDOS in QEMU or VirtualBox (which are far better emulators than NTVDM is, right?), it creates this picture: I expected it to also run on Windows 10. However, when I try to run it on Windows 10, I get this error: What does that even mean? My program is not 16-bit, it's 32-bit, so why is some 16-bit subsystem even being run? And what does the "error 4001h

Please, what is the

They are 1985 DOS apps, so trapping for them was easy... capture any process that launches under NTVDM.exe Now, the problem is finding out which program NTVDM is actually running under the hood. Apparently there are a coupleof the 1985 programs that they SHOULD be allowed to run, so I need to see the actual EXE name that is hiding under NTVDM. WqlEventQuery query = new
