Just a day after its release, the first firmware updates are now available for the new Surface Pro X. As is usual with these types of updates, the focus is firmly on improving system stability. There's also a single update geared towards improving battery performance.
Here's a look at all of what's new, as detailed in Microsoft's release notes:
- Surface UEFI– Firmware: 3.444.140.0 improves system stability.
- Surface System Aggregator – Firmware: 14.57.139.0 improves battery performance.

- Surface Pro X Power Engine Plug-in Device: 1.0.0800.0 improves system stability.
The Surface Pro X is an evolution of Microsoft's Surface Pro design language, slimming down the bezels and bundling the hardware in an overall smaller package. That's largely because of the new Microsoft SQ1 ARM chip that powers the machine, making it the first Surface Pro to run Windows 10 on ARM. The Surace Pro X also pairs with Microsoft's new Surface Slim Pen, which takes a flatter form than previous Surface Pens and can be wirelessly charged in a cradle above the detachable keyboard.
The Surface Pro X is available to buy now with prices starting at $999.
