To disable it, click the Start or Windows button on the lower left corner of your screen and search for Settings. Next, go to Accessibility and select Keyboard. Lastly, find Filter Keys and toggle off its button to disable.

First, press Windows+R to open a command window where you will need to type “appwiz.cpl”. After clicking the OK button, a control panel will appear where you can uninstall programs.
Next, look for Logitech Software, right-click on it, and select Uninstall. Once successfully uninstalled, remove the receiver from your device and restart it.
Turn on your device and keyboard after. Plug in the receiver again and wait for the instruction for installing the driver. Just follow the installation process and make sure to check if it is successfully installed from the list of installed programs later on.
Restart HID services
To restart HID service, click on the Windows icon and click Windows Administrative Tools. Choose Services then look for the “Human Interface Device Services” and go to “Properties“.
Search for the General tab and from the Start type, choose Automatic and click OK. Be sure that the Service Status is Running.

Once done, check the installation by clicking Action and selecting Scan For Hardware Changes. This should refresh the driver list and remove the exclamation mark.
It is important to update all the drivers and not just the one specifically for the keyboard.
You can install Windows OS updates to conveniently update all the drivers with fewer worries. Once installed, go to Windows Settings and click Update and Security to update your device’s Operating System.
