Never install solely because a device name or version looks similar.

Check Windows Update for an applicable driver

Open Settings.
On Windows 11, choose Windows Update. On Windows 10, choose Update & Security → Windows Update.
Select Check for updates.
When available, review Advanced options → Optional updates → Driver updates.
Install only an applicable update and restart only if Windows requests it.

Verify the result and recover safely

After updating

Test the device, check Device Manager for warning symbols, and confirm the installed version only if an update was applied.

If the device works worse

Open Properties → Driver → Roll Back Driver when available. Otherwise use the restore point or reinstall the previous official package.

Stop when the device works correctly. A numerically newer driver is not automatically better for every computer or Windows build.
