Fix: Logitech MK270 Some Keys Not Working

Not just the antivirus software, third-party applications can also sometimes be problematic for other apps. Hence, we recommend you temporarily disable the antivirus software, restart the computer, and check if the problem is solved. Otherwise, remove third-party apps and check if the keyboard is working properly.

You should also remove the Logitech software. Because it can sometimes conflict with the hardware. After removing the app, check if this method does not trick. You can later reinstall the software, if required.
