After inserting the USB, I received a pop up to download firmware driver at this link

Wireless Keyboard 850 | Microsoft Accessories

After downloading and running the 2 drivers (Mouse Keyboard Centre and Wireless 850 Keyboard Update), keyboard is still not responding/ not working.

I have turned on Filter Keys under "Ease of Keyboard Access", updated drivers under Device Manager, uninstalled and reinstalled drivers. I have ran Keyboard Troubleshooter. Keyboard is still not working.

My OS is Windows 10 Pro and there are no pending Windows Update. Windows 10 is at the latest update version.
