Oldest GUI application that still runs on Windows 11
90Original Thinker
A hands-on probe of Windows 11 backward compatibility that diagnoses why 1992 NT pre-release binaries do or don't run.
What it adds
Tests exactly how far back Windows 11 binary compatibility reaches. It pins the cutoff to specific ABI changes in late-1992 NT builds: the move from cdecl to stdcall and the system crtdll.

Its strongest original claims
- FREECELL.EXE from Win32s dated 22-Feb-93 runs fully playable unmodified on latest Windows 11.
- NT builds up to mid-1992 used cdecl instead of stdcall for API calls, causing arguments to be removed twice and crashes.
- CDPLAYER.EXE from NT Build 347, linked 16-Nov-1992, runs on Windows 11.
- Other Build 347 programs crash in their bundled C runtime, but CDPLAYER uses the system crtdll.dll, which Windows 11 still ships in SysWOW64.
- A small DLL emulating a CD-ROM with fake audio lets the 1992 CD player actually play audio.
