Microsoft began work on Windows on Arm (WOA) long before the original iPad

Microsoft recently released a new Building Windows 8 blog post which talked about the development of Windows on ARM (WOA). With that blog post, a photo of a post-RTM version of Windows 7 was revealed. Details of this photo reveal that Microsoft has been working on Windows on ARM for longer than we though, a lot longer in fact.

The recent Building Windows 8 blog post revealed many new features and details about Windows on the ARM processor architecture. Along with the blog post, a video and a couple of photos were revealed. One of the photo’s is of a ASUS phone, running a post-RTM version of Windows 7. This special version of Windows 7 is running on an ARM processor.

First seen on iStartedSomething, taking a look at the photo details reveal that Microsoft have been working on WOA for a long time, even before the original iPad launched back in 2010. The photo was taken on the 22nd of January 2010, almost a week before the iPad was set for announcement.
