Microsoft Windows 1.01, the first public version of Windows, was released on November 20, 1985. It is shown here running on an IBM PC XT (Model 5160) with a CGA Display.
You can also run Windows 1.01 with an EGA Display.

The above simulation is configured for a clock speed of 4.77Mhz, with 256Kb of RAM and a CGA Display, using the original IBM PC Model 5160 ROM BIOS and CGA font ROM. Even though the CGA was a "Color Graphics Adapter," the only CGA mode that Windows supported was the 640x200 2-color mode, hence its black-and-white appearance.
This PC XT configuration also includes a 10Mb hard disk with Windows 1.01 pre-installed. This particular configuration will NOT save any changes when your browser exits, since it has been pre-configured to always start Windows 1.01 in the same state.
NOTE: The Windows 1.01 mouse pointer can be controlled with your mouse, but only when your mouse is within the "CGA Display" window. This is a restriction imposed by your web browser, not PCjs.
For more control over this machine, try the Control Panel configuration, featuring the built-in PCjs Debugger, with save/restore enabled.
