“NVIDIA GeForce GTX 1050 – Device adapters 23.21.13.8808 required to support Windows Mixed Reality features. NVIDIA GeForce GTX 1060 – Device adapters 23.21.13.8808 required to support Windows Mixed Reality features.

You should have been prompted to download the firmware update a few days ago via the usual methods. If not, you can grab them manually from the official site. The file will let you install drivers selectively if needed.
