> There were at one point switches to the WIN command to tell it whether to come up in real mode or 286 protected mode. In the latter it definitely did use the features of protected mode.

Windows 3.0’s WIN.COM supported:

/R for real mode (8086)

/S for standard mode (16-bit protected mode)

/E for 386 Enhanced Mode (32-bit virtual machine manager (VMM), running Windows in VM1, and DOS apps in VM2+)
