We are not uncommon for Microsoft to try in the mobile market, from the beginning of Windows Mobile, to the later Windows Phone and so on. Over the years, Microsoft has repeatedly lost battles in this booming market, but for geek users, the most interesting thing seems to have been to brush Microsoft's different mobile devices into desktop Windows. Prior to this, The last flagship of Microsoft Win10 Mobile, Lumia 950XL, has been successfully brushed into the complete WIndows 10 system, and now, the original Surface Duo, which carries Microsoft's new generation of mobile dreams, has also been attacked by developer Gustave Monce and run on the Win11 ARM64 system.
As can be seen from the released photos, the current surface Duo running the same system as the desktop, Win11 native obviously did not adapt for dual-screen devices, so the phone can only display half of the screen screen at present.
It is worth mentioning that in the list of Microsoft account devices displayed by the developer, the Surface Duo equipped with the Win11 system is actually listed, and it can also be correctly displayed as Windows in the system column. In fact, before this, the purpose of this dual-screen mobile phone development is to carry the Windows 10X system, so it should have done a lot of tests before release, so that the system can be correctly identified seems reasonable.
Since Microsoft has always provided arm versions of Windows, there has always been a group of developers maintaining Windows on ARM (WOA) projects for multiple devices, and you can easily find woa projects and their open source versions on Github, but it is not so simple to really brush these systems.
