Joins a number of patches released for Windows 8.
Microsoft has released a firmware update for the Surface RT tablet that improves the device's performance.
In addition to the launch of Windows 8's first critical security patches, the software firm has issued a system firmware update for Surface RT, as well as Windows RT operating system updates.
The fixes, which are listed under a "cumulative update", includes performance improvements "when you wake the computer and when the computer is asleep, in order to improve battery life". A separate patch also fixes "an issue that may prevent Windows Store Apps from being installed fully."
While initial reviews of Surface mentioned the tablet could be slow at times, reports are suggesting that the update in question improves application launch times. Apps apparently launch around two seconds faster than before.
However, the update seems to failed to address an audio stuttering issue with Surface RT.
