Yesterday, Microsoft rolled out its first firmware update for the Surface Studio. The company is also issuing a series of updates for the Surface Pro 4. Here"s the list of updates (via Thurrott):
Microsoft – System – 11/4/2016
Microsoft – Firmware – 12/8/2016
Microsoft – System – 12/9/2016
Intel Corporation – HIDClass – 11/10/2016
Microsoft – Firmware – 12/7/2016
Microsoft – System – 10/11/2016
And just like the new firmware for the Studio, we have no idea what"s included in these. Microsoft does have pages dedicated to Surface update history, but as usual, the company is unable to produce a changelog at the same time that the update is actually released.
Obviously, the dates would indicate that the updates are older; however, while there"s one fix for the Realtek High Definition Audio driver listed from December 8, there hasn"t been anything else since August 30.
It"s also entirely possible that other Surface devices are receiving firmware, besides the Pro 4 and the Studio. Unfortunately, until Microsoft decides to post some changelogs, it will just be a guessing game.
