Owners of the Surface 3 and Surface Pro 3 tablets should be able to download new firmware updates for both devices. Microsoft started rolling out the updates this week, along with some new Intel HD Graphics drivers.

So far, there's no word on what is contained in these updates. Microsoft has not yet posted a change log on its official Surface update history pages. When this happens, we will update this post with the information.

Thanks to Alex for the tip!
