Windows 10: replacing the key?

Bought a pc with what turns out to be a less than legit key for win home 10. From what I have been able to gather, I should be able to get a legit key and register it. Is there a direct site I can purchase the key I didn't find it here but... this site is freaking immense!, and what other precautions should I take?

Follow either of these steps to fix the issue with the Active window hiding behind.

1. Press Windows key + X key and click on Control Panel.

3. Click or tap onEase of Access Centre.
4. Click on Make the Mouse Easier to Use was uncheck Activate Window by hovering over it with the mouse.
5. Check if issue is resolved.

Method 2:
I would suggest you to completely uninstall the touchpad driver and reinstall it. Kindly follow the below given steps.

1. Press “Windows key + X” and click on “Device Manager”.
2. In the list of devices, you should see the touchpad drivers.
3. Right click on the device and then select "Uninstall".
4. In the uninstall dialog, make sure you select the option to delete the driver package from the system. This causes the driver package installed earlier to be deleted.
5. In the Action menu of Device manager, select “Scan for Hardware changes” option. This will cause the device driver to be reinstalled. Once the driver is installed, close all windows and restart the computer.
