Hi Paul,
Thank you for writing to Microsoft Community Forums.
I understand the inconvenience you are facing with the working of Mouse. I appreciate your effort in trying to fix the issue.
Provide us additional information to assist you better with this issue:
- What is the make and model of the computer?
- Is your computer connected to domain network?
I would suggest you to follow the steps mentioned below and let us know if that helps.
- Close all your open apps: Then see if the cursor improves. If it does, the number of open apps might have been interfering with your PC’s connection to the mouse.
- Restart your PC. This will refresh the drivers.
- Change the cursor settings. Select the Startbutton, and then select Settings > Devices > Mouse > Additional mouse options > Pointer Options and adjust the pointer speed.
If the issue still persists try installing the latest edition of Mouse and Keyboard Center and check the status of the issue.
I see that you have already tried changing the Bluetooth adapters, however please refer the section ‘**To manually install the Bluetooth driver’**and ‘Uninstall the Bluetooth adapter in Device Manager’ from the article **Fix Bluetooth problems in Windows 10**to verify whether the steps you have tried was in the same procedure.
You may also the section Hardware support if the issue still persists.
Hope it helps.
