You can install the October 2021 firmware update for Surface Pro X SQ1 and Surface Pro X SQ2 via Windows Update if your device runs Windows 10 2004 or newer. Note that, unlike Windows Update, you cannot uninstall firmware updates on Surface devices. Although Surface Pro X SQ1 and SQ2 receive shared firmware update, this does not apply to the third-gen Surface Pro X Microsoft announced a few weeks ago.
In case you missed it, this month, Microsoft released firmware updates for Surface Pro 7 Plus, Surface Laptop 2, Surface Duo, Surface Duo 2, Surface Studio 2, and many other computers. Some of those updates added new features, such as Windows 11 battery optimizations on Surface Pro 7.
