Microsoft's Surface Pro 3 and 4 get a bunch of firmware updates

Microsoft is releasing new firmware updates for both the Surface Pro 3 and Surface Pro 4 today, some of its oldest supported devices in the lineup. Indeed, the Pro 3 came out almost four and a half years ago, so it's certainly notable that it's still receiving updates.

Here's what's new for the Surface Pro 3:

Windows Update History Name

Device Manager Name

Surface – Firmware – 3.11.2550.0

Surface UEFI – Firmware

  • 3.11.2550.0 improves battery stability for devices not in use.
Surface – Firmware – 38.14.80.0

Surface – System – 2.0.1350.0

According to Microsoft's value indicator chart, these updates improve security with no effect on other categories like reliability, battery life, connectivity, compatibility, and performance.

The Surface Pro 4 got a few more updates than that, also improving security and battery stability.
