I've clicked "Update Driver" on all the drivers in Device Manager for the Dongle and Keyboard.I've tried the keyboard right next to the laptop and about half a metre away.
I've plugged the USB dongle directly into my work laptop, same problem. My wired keyboard and mouse work using the same USB-A ports. I've tried another USB-A port in the Hub (my PC only has USB-C). However, there are YouTube videos showing it used on Windows 10 and on Microsoft's official page for this keyboard here shows Windows 10 has full, not limited support.
I've recently bought the Microsoft All-in-One Media Keyboard and was told the guy couldn't getting it working on Windows 10 but it worked on Windows 8.1 fine.
