ReProgman – The Windows 3.1 interface on PC and Mac

Revisiting Nostalgia with ReProgman

Developer Mayuki Sawatari has unveiled ReProgman, a modern homage to the iconic Windows 3.1 Program Manager. For those unfamiliar with this piece of computing history, progman.exe served as the primary interface for Windows prior to the introduction of the Start menu in Windows 95. Now, thanks to Sawatari’s innovative efforts, this nostalgic interface operates seamlessly on both Windows 11 and macOS.

For the younger generation of tech enthusiasts, it’s essential to understand that before the advent of the desktop and taskbar, computing was a different experience. Users interacted with a singular gray window filled with sub-windows, each housing program icons arranged in a neat grid. A simple double-click would launch the desired application, providing a straightforward yet limited view of the Windows environment.

Upon launching ReProgman, users are greeted with a familiar interface reminiscent of the early ’90s. The application scans the Start menu on Windows or the Applications folder on Mac, transforming each folder into a group and storing this configuration in a dedicated Groups.ini file. Notably, any changes made within ReProgman do not affect the actual shortcuts on the system, allowing for a nostalgic experience without the risk of altering current setups. Users can manually re-import missing items, ensuring the interface remains up-to-date with their preferences.

The functionality of ReProgman captures the essence of its predecessor. Users can drag and drop icons between windows, with the option to copy them by holding down the Ctrl key. The Window menu offers classic arrangements, such as cascading or tiling layouts, while minimized windows revert to icons at the bottom of the main window. Even the exit dialog box has been thoughtfully recreated, signaling the end of a ReProgman session rather than a Windows one.

The inspiration behind this project is as intriguing as the application itself. Sawatari, in a message shared by Tom’s Hardware, mentioned that he simply requested Claude to assist in building this clone. The initial version, crafted in just an hour, was surprisingly functional, though it required further refinements to perfect the user experience.

For those interested in the technical details, the project’s git repository includes a comprehensive specification document that meticulously describes the interface pixel by pixel, based on 640×480 screenshots of the original Windows. This attention to detail reflects the era’s design nuances, such as the distinct pixel measurements that differentiated window frames and menus.

ReProgman is available as a standalone binary, though Mac users should be aware that the distributed version is not notarized. To run it, they will need to execute xattr -cr ReProgman.app or utilize Sentinel for permission. The code is released under the MIT license, promoting further exploration and development.

It’s worth noting that the scope of ReProgman is somewhat limited, currently supporting only Windows 11 on x64 and Arm architectures, as well as macOS on Apple Silicon. Users still on Windows 10 or Intel Macs may find themselves reminiscing about the past through emulation rather than direct interaction.

While ReProgman may not redefine your computing experience, it offers a delightful trip down memory lane, providing a brief yet enjoyable encounter with the simplicity of early operating systems.
