Microsoft is rolling out a new set of firmware updates for its ARM-based Surface Pro X devices. There are two sets of updates for both models of the Surface Pro X, meaning those with SQ1 and SQ2 processors are receiving stability improvements and other fixes.

First up, the new Surface Pro X model with the SQ2 processor is getting new firmware updates that improve the overall device stability and reliability. In addition, this batch brings enhancements to the external monitor connection experience and also addresses a variety of issues. You can find the full details below:

  • Surface System Aggregator - Firmware: 1.207.139.0 Improves device stability and reliability.
  • Qualcomm(R) Wi-Fi B/G/N/AC (2x2) Svc - Network adapters: 1.0.1540.0 Addresses critical security vulnerabilities and improves connection stability.
