Microsoft has pushed out Windows RT 8.1 Update 3 that brings the Start menu to the OS. Seeing as Microsoft has not publicly announced this release, we are still working to determine the exact update but it looks like it is KB3033055 that enables the feature.
As you can see from the image in this post, the Start menu looks similar to that of Windows 10 with the inclusion of tiles but the left side of the menu looks closer to that of Windows 7.
Microsoft said that they would bring a Start menu to the OS during the month of September and this update delivers on that promise.
For those that are curious, you do have the option to retain the Start Screen if you do not want the menu.
While this feature is not quite as good as Windows 10, it should make those still using the Surface 2 and similar devices happy as it does give them some parity between Windows 10 and Windows 7. And considering how old these devices are, any update, at this point, should be taken with a smile as Microsoft has essentially moved on from Windows RT and left it for the vultures.
If you have a Windows RT device, start searching for updates as Windows 8.1 update 3 is now rolling out. If you do install this release, let us know if you find anything else that his been updated too.
