The USB receiver for Microsoft Wireless Comfort Desktop 5000 is pre‑paired at the factory and is not replaceable or re-pairable with a generic or different receiver. When the dongle is lost, the practical options are:
- Replace the desktop/mouse/keyboard set
- Purchase a new Microsoft desktop set that includes its own receiver.
- Check warranty and request a replacement if eligible
- Verify whether the desktop set is still under warranty. For Microsoft PC accessories like Wireless Comfort Desktop 5000, warranty is validated using proof of purchase and the terms listed under Hardware warranty, services, and repair.
- If it is within warranty coverage, submit a replacement request for the accessory.
If the product is out of warranty, a new set is required because a standalone replacement receiver is not provided.
