A new firmware update is rolling out to users using the Microsoft’s Surface Pro 4 2-in-1 Windows 10 device. These updates are usually provided via the Windows Update service, and are delivered in stages to Surface customers. So, if the update is not available on your machine now, don’t worry, it should be available in the coming days.
In case not, please manually check Windows Update later.
Here’s the official changelog for July 11 release:
Windows Update History Name
Device Manager Name
Surface – Keyboard – 1.1.504.0
Surface Type Cover Filter Device
Alternatively, you can visit the Microsoft Download Center to download the Surface Pro 4 update (msi file) manually, but this is recommended for advanced users or enterprise deployment or at least for a user who knows how to deal with it.
