Ran into an issue yesterday when my mouse randomly wouldn’t “connect.” It showed up the in the device manager but never would actually work.
One issue I saw was there were no “hardware” device functions listed if I right clicked and went to properties on the device… this was a red flag so I started messing around.
2 hours later I finally fixed it.
Try this first:
1. Remove the device from Control Panel\Hardware and Sound\Devices and Printers.
2. Click the connect button on the mouse (you should see the lights alternating flashing green/red.
3. Inside of Devices and Printers click add device.
4. Right click the “Microsoft Bluetooth Notebook Mouse 5000” option and click properties.
5. Under bluetooth services check ”Drivers for keyboard, mice, etc (HID)”
6. Click Okay
7. You should see a “Installing Driver Device Software” notification window.
8. In device manager you will now see the device with a clock on it.
9. After about 30 seconds you should get a popup that says Bluetooth HID successfully installed, and then in Devices and Printers the little clock is gone and you have mouse access!
So if the above didn’t work don’t worry you can still do it. The first step is to take control of the existing mouse driver.
1. As administrator navigate to C:\Windows\System32\Drivers.
2. Find the mouclass.sys file and right click and select properties.
3. Change to the security tab, and click “Advanced” button.
4. Click Owner, then Edit button.
5. Select your user, and hit okay, and okay again, and okay one more time. You should be back on the security tab.
6. Under security, select edit and remove all permissions for System and TrustedInstaller. You can do this by clicking the “Deny” Full Control box.
7. Now try to reinstall the mouse as above, but this time you will see an exclamation point. On the mouse, once you see this go and delete the mouclass.sys file, and hit trouble shoot. It will say something about missing driver, just hit okay a couple times, and you will be up and running!
