Microsoft has started to issue updates to its Surface RT device this week with the company's first monthly Patch Tuesday since Windows 8 and Windows RT's launch on October 26th. The software maker has taken the opportunity to issue a system firmware update for Surface, which appears to have improved performance.

I managed to install seven Windows RT updates today on my Surface RT and I compared the system to an unpatched one and noticed improvements in app launch times. On average, apps launched around two seconds faster than before, a noticeable improvement. Unfortunately, the updates don't appear to have adressed an audio stuttering issue with Surface RT. Out of the seven patches, Microsoft also managed to patch two security issues with Windows RT. We are testing the firmware update fully and we'll let you know if we notice any additional improvements.
