Why has the contrast and screen views been changed after a Windows 10 upgrade?

[Windows Central Question]

Windows did an upgrade upon shut down two nights ago. Upon using my desktop the next day, the appearance has changed. All screens are now black with white text (Microsoft Office programs (word, excel), pdf files, web pages, etc. How can I return to the original settings with a white background and black text? Please help!

It sounds like high contrast has been enabled somehow.

Go to Settings > Ease of Access > High contrast, and turn it off.
