A Curious Confluence of Ideas​

Windows has long flirted with ARM devices, from the early days of the Surface RT to more modern incarnations of Windows on ARM. However, Monce’s project is a game changer by reinterpreting “ARM” literally—switching from the typical chip architecture to the notion of a wrist-worn device. Essentially, the concept transforms your smartwatch into a potential portable Windows machine. Even though it originated on April Fools’ Day, an updated note boldly asserts the project’s serious ambitions, stating it is “not finished either,” yet far more than just a joke.
This isn’t Monce’s first foray into defying expectations: previous ventures like DuoWOA (aiming to install Arm64 Windows 11 on Microsoft’s Surface Duo) and LumiaWOA (bringing Windows 10/11 to the Nokia Lumia 950/950XL) have already set the stage for this latest experiment. By reimagining Windows not just as an operating system for desktops or tablets but as software that can run on a tiny smartwatch, the project challenges both our technical assumptions and our perceptions of device boundaries.

Background: Windows Meets Nontraditional Hardware​

Monce’s approach, which has captured attention on platforms like The Register, builds on a long history of Windows on ARM projects that push hardware beyond its intended limits. Unlike previous attempts where devices built with ARM processors were simply repurposed, this project innovates by installing a UEFI (Unified Extensible Firmware Interface) bootloader on a Google Pixel Watch 3. The watch, typically a well-specced Android gadget, becomes the testbed for a Windows Preinstallation Environment (WinPE) image—a stripped-down version of Windows designed for setup and recovery.
Key details include:

• Device Under Test: Google Pixel Watch 3
• Software Component: An ARM64 build of Windows PE
• Method: Installation of UEFI followed by enabling USB mass-storage mode, though the final stage of installing a full OS remains undocumented
