Microsoft Wireless Desktop 850 Keyboard & Mouse

Get the convenience of wireless and the productivity of a full-size keyboard and mouse with the Wireless Desktop 850.

Wireless Freedom and Security at an Affordable Price

Enjoy the freedom and convenience of wireless technology. Confidently roam up to 15 feet away from your PC while maintaining a strong wireless connection. Or, take the mouse separately to use with a laptop while traveling—the tiny transceiver conveniently snaps into the bottom of the mouse when it’s time to pack up and go. Setting up the keyboard and mouse is simple—just insert the batteries, plug in the tiny transceiver, and start typing! This keyboard also has Advanced Encryption Standard (AES), which is designed to help protect your information by encrypting your keystrokes.



1) Reliable wireless connection - Enjoy the 2.4-gigahertz (GHz) wireless technology, which delivers a reliable connection with up to a 15 foot range, with virtually no interference.

2) Advanced Encryption Standard (AES) 128-Bit Encryption - This keyboard features Advanced Encryption Standard (AES*) technology, which is designed to help protect your information by encrypting your keystrokes. Each keyboard is permanently paired with its receiver at the factory—no key information is ever shared over the air.

3) Windows shortcut keys - Quickly access frequently used tools, like the calculator, zoom and audio controls by using shortcut keys.

4) Designed for comfort – in either hand - Superior comfort that’s designed to fit your right or left hand.

5) Microsoft optical technology - Precise optical tracking technology provides highly responsive cursor control.

6) Snap-in transceiver - Plug the wireless receiver into your computer’s USB port when you’re ready to work. Then snap it into the bottom of your mouse when you travel, and the mouse will automatically turn off.
