You can now install Windows on the Microsoft Surface Duo dual-screen smartphone

It’s been a few years since Microsoft stopped developing Windows-based operating systems for smartphones and ended support for existing devices that shipped with Windows 10 Mobile. But if you want to run Windows on a smartphone made by Microsoft, now you can. You can’t do much with it yet.

the Microsoft Surface Duo is a dual-screen smartphone that runs a suite of Microsoft apps on Google’s Android operating system. But developer Gustave Monce revealed earlier this year that he’s been porting Windows 11 to run on the device, and now he’s published instructions and software that anyone can use to run Microsoft’s desktop operating system on Microsoft’s mobile device.


Windows 11 on Surface Duo is the latest achievement of the WOA Projectwhich previously ported Microsoft’s desktop operating systems to work on phones like the long-discontinued Microsoft Lumia 950XL.

This is possible because while Windows used to be an operating system that required an x86 processor, Microsoft is now also creating versions for ARM processors. Most people who want a Windows on ARM device will need to buy a laptop or tablet with a Qualcomm processor that comes with Windows preinstalled, but the folks behind Project WOA have hacked their own Windows on ARM (WOA) devices together.

That said, it’s still early days for Windows on the Surface Duo. Monce says the software is “an early preview” at this point, and almost nothing works. CPU frequency, USB, side buttons, and opening and closing the device to sleep and wake it up work. But very few others do.

In fact, so far it looks like only one of the Duo’s two displays works with Windows – I guess you could call it the Surface Uno?

Also, to install Windows on the Surface Duo, you’ll need to erase all of your Android data. So be sure to back up everything important before you start.

And the installation process has only been tested on first-generation Microsoft Duo devices with 128 GB of storage. Got a 256GB model? There is no guarantee that it will work. And if you have a newer Surface Duo 2so you definitely shouldn’t try installing Windows 11 using the WOA project guide.

With that out of the way, here’s everything you need to replace Android with Windows 11 on the original Surface Duo:

Not a fan of Windows, but intrigued by the possibilities of running something other than Android on the Surface Duo? Monce notes that the UEFI firmware can also be used to boot main Linux on the phone.
