Hi,
Thank you for writing to Microsoft Community Forums.
We understand how frustrating it could be when devices do not work the way they supposed to and we truly appreciate the time and effort that you have taken to work on this issue. However, we see that the wireless Desktop 7000 you are currently using is not compatible with Windows 10, which might be the reason for the issue you are facing.
We would suggest you to follow the steps mentioned below to install the driver from the repository and check if it resolves the issue.
- Open Device Manager.
- Right click on wireless keyboard and mouse driver and select Update driver.
- Click on Let me pick from a list of device on my computer.
- Click on Browser my computer for device software.
- Select Human Interface Device and click on USB composite device.
- Then follow on-screen instructions to complete the process.
If the issue still persists, check for the version of Microsoft Mouse and keyboard center installed on your computer, as entertainment keyboard 7000 and wireless laser mouse 8000 is supported by Microsoft Mouse and Keyboard Center 2.3. You can download Microsoft Mouse and keyboard Center 2.3 from Download Center.
