Note: If your problem theme did not come from the Microsoft Store, simply download it again from where ever you got it from instead, and then set it as your theme again. If you have trouble deleting either, you may need to take ownership accordingly and then delete them after you complete that procedure.Īfterwards from Settings -> Personalization -> Themes -> click on Get more themes in Microsoft Store and download the theme you deleted and then set your theme back to it again-see if that resolves. From Settings -> Personalization -> Themes you can first simply try to first change whatever theme you have set when the problem occurs to a different theme, and then change it back to the theme you had set-see if that resolves.įrom Settings -> Personalization -> Themes change your current theme to a different theme and then go to %windir%\Resources\Themes or %localappdata%\Microsoft\Windows\Themes or %appdata%\Microsoft\Windows\Themes and delete the theme (and correlated folder name too if applicable) you had set when the message popped up.Note: Try any of these individually in no specific order. As per the Cannot find and save a theme error in Windows 10 after update post, I put some potential solutions together with a bit more detail plus another idea.
