Q: After installing Windows 10 update, I see unexpectedly light-themed UI elements (e.g. address bar) in File Explorer and unreadable text in context menus when using dark theme. How do you fix it?
chicagotech.net: Windows 10 Update 1809 may cause this problem. Next update may fix the problem. A temporary solution is going to Settings > Personalization > Themes and reverting back to the default Windows theme. After that, feel free to return to your preferred theme.
