Windows 10: Screen backgrounds have all turned black instead of usual white?

Since recent Windows 10 update my screen backgrounds have all turned black instead of usual white. Can't see how to change this in Personalisation/Settings even after changing background from 'dark' to 'light' - I'm so angry their stupid software took in upon itself to alter how I'd set the laptop up :-(. Any advice gratefully received! Thanks, Karen

MicroSoft home screen background screen turned black with white letters instead of whit with black letters. all other screens are normal black lettering on white.

Needs assistance finding settings for screens - they black instead of white. I think Grandson hit wrong buttons. My email background and excel, word are all black.

Microsoft 10 - background is black

Hi,

I installed Windows 10 and now the background on my excel files is black, making the writing illegible. How do I change it back to white background. I also noticed my search bar for google is also black, instead of the usual white.

Thanks.
