Microsoft have been true to their word with the Surface tablets, releasing updates every month and addressing user feedback, fixing bugs and generally doing a good job of making sure the devices operate as they should. Something Microsoft has to keep up with if they want to stand out from the crowd at all, given that the market is already flooded with fans of Apple and Samsung devices.
The Surface Pro has been given a few tweaks, such as UEFI firmware update that enables the PXE boot feature. Although that feature is only available when using the Surface Pro Ethernet Adapter due to the UEFI integration needed to implement PXE boot. The Trackpad Settings driver has also seen an update for the Surface Type Cover which enables interaction with the Trackpad Settings app for Japanese customers and continued improvement in Wi-Fi connectivity and stability.
The Surface RT sees similar updates but obviously it has a different feature set to the Pro, it still gets a UEFI firmware update, only this time it is to enhance the Surface RT speaker volume and improves system stability. There is also a driver pack that improves overall performance and works with the updated UEFI firmware to enhance Surface RT speaker volume. Last of all the trackpad settings driver for the Surface Type Cover is updated to enable interaction with the Trackpad Settings app for Japanese customers.
