IBM marketed "OS/2 for Windows" which made it sound like a compatibility layer to make Windows behave like OS/2. In truth it was the OS/2 operating system with drivers and conversion tools that made it easier for people who were used to Windows.

Untrue. OS/2 for windows leveraged the user’s existing copy of windows for os/2’s compatibility function instead of relying on a bundled copy of windows, like the “full” Os/2 version.

Os/2 basically ran a copy of windows (either the existing one or bundled one) to then execute windows programs side by side with os/2 (and DOS) software.
