The Microsoft Wireless Desktop 3050 keyboard connects using its dedicated USB wireless receiver. Windows 11 does not support pairing this model directly over Bluetooth, and it cannot be used without the matching USB module (receiver/dongle).
Without that USB receiver, the keyboard cannot be installed or used on Windows 11. The only options are:
- Obtain the original USB receiver that was paired with this specific keyboard (for example, from the seller).
- Replace the keyboard with a complete Microsoft wireless set that includes its own receiver, or use a Bluetooth keyboard that can pair directly with Windows 11.
If a compatible receiver is obtained and plugged into a USB port on the Windows 11 PC, Windows will automatically install the necessary drivers and the keyboard should start working without needing a manual user guide.
