In the past few years, we have seen hackers run all kinds of software on smartphones, including early versions of Windows. Hacking Jules has posted a new video that shows Windows 10 running on an iPhone X. The UTM app for iOS was used to pull this off. It is a virtual machine host that lets you run Windows, Android, and more on your smartphone.
Hacking Jules is using Windows 10 v1607 for this video. While many of the features work, the experience can be slow. Apparently, the normal boot time is around 20 minutes.[where to find it]
