Hi
Did you try to change any of the Key size settings in windows using the Font size settings. Basically Windows 10 hates it if you even try to change any of the Font sizes and I had my changed once and it almost ruined my whole Windows OS experience by just trying to change the font sizes. Even the setting for Clear Type if I tried to change it it really messed up the functionality of the Operating System. I would go back and change it back to default if you did change something.
