Frequently Asked Questions:

Is the Microsoft Wireless Desktop 850 compatible with Windows 11?

Yes, the Microsoft Wireless Desktop 850 (PY9-00001) is fully compatible with Windows 11, as well as Windows 10, 8, and 7. It also offers limited functionality with Mac OS X (v10.4–10.7).

What is AES 128-Bit Encryption and why do I need it?

Advanced Encryption Standard (AES) is a specification for the encryption of electronic data. This keyboard uses AES technology to encrypt your keystrokes before they are sent to your computer, protecting your passwords and credit card numbers from being intercepted wirelessly.

How do I connect the keyboard and mouse to my computer?

This desktop set uses a simple plug-and-play setup. Insert the included batteries into the keyboard and mouse, then plug the small USB transceiver into an available USB-A port on your PC. The drivers will install automatically, and you’ll be ready to work in seconds.

Where is the USB wireless receiver located in the packaging?

The USB transceiver is often tucked into a small slot on the underside of the mouse or held in a cardboard insert within the box. If you are traveling, the mouse features a convenient "snap-in" slot on the bottom to store the receiver safely.

Can I use the mouse and keyboard independently?

Both the keyboard and mouse communicate through the same single USB transceiver. While you can use just the mouse or just the keyboard, they both require that specific receiver to be plugged in to function.

Does the keyboard have a CAPS LOCK indicator light?

To maximize battery life (up to 15 months), the Model 1455 keyboard does not feature an onboard LED light for Caps Lock. However, Windows typically provides an on-screen notification or sound if configured in your ease-of-access settings.

What should I do if the keyboard or mouse stops responding?

First, ensure the USB transceiver is plugged directly into the computer rather than a hub. Check that the batteries are fresh and properly inserted. If issues persist, try pressing the small "Connect" button on the bottom of the devices to re-sync them with the receiver.
