Surface Pro X receives December firmware update

Microsoft is rolling out a handful of firmware and driver updates for ARM-based Surface Pro X devices, improving some aspects of the experience. There are two different sets of updates, one for the original Surface Pro X model with Microsoft SQ1 chipset and one for the version with SQ2 chipset.

For those who don’t know, these chipsets are custom variants of Qualcomm’s Snapdragon 8cx, the SQ1 based on the original 8cx, and the SQ2 based on the 8cx Gen 2, which is slightly faster than the original. However, although the chipsets are similar, the two devices receive different sets of updates.

In Windows Update, updates will appear as a single item, with the name “Microsoft Corporation – System Hardware Update”, but it actually contains updates. If you have the latest Surface Pro X with the SQ2 chipset, you will get the following updates.

As usual, sometimes Surface firmware updates are rolled out gradually, so they may not appear immediately to everyone. If you still don’t see the updates, you might have to wait a bit longer. While it’s not yet available to everyone, Microsoft recently introduced x64 emulation for ARM devices like Surface Pro X for Windows Insiders, so if you’ve slowed down the purchase because you couldn’t run all of them. apps, that will change soon.
