Changing the background color of apps

Hi,

There may be settings on your computer that has been changed that's why the background color of your apps has also changed. With Chrome, you may have added a color change extension to it which allows users to change its background color. With Microsoft Office
applications, there are options to change its background color depending on which application you have open. Below are some of the option:


Change the background or color of a document


Add or change the background color of cells


Change the Office theme

However, for us to properly isolate this issue, we would like to ask the following information:

• Have you made any changes or performed any updates on your computer before this happened?
• Aside from adjusting the appearance settings on your PC, what other steps have you tried?

If possible, we would like to ask for a screenshot of your Office applications to help us sort this out.

Looking forward to your reply.

Regards.
