Inside, I navigated to the bottom to find the exact registry entries from HKEY_CURRENT_USER\Control Panel\Colors. There, I renamed it to something suggestive (ie customized) then right clicked on it, open with - notepad. I had to go to %USERPROFILE%\AppData\Local\Microsoft\Windows\Themes and copied my theme to desktop. I found a way to make Word / Excel / possibly other apps with grey background after meddling with an already created theme - the theme I liked. Also, editing high contrast themes is a pita because for every text color change you have to save the theme with a new, different name. Even with changing their options and making my own, something always doesn't show correctly.

I also tried other themes (ie high contrast themes) but they are not really what I need, they have too much contrast. Sorry for having my 1st post as a request / support question, but I am new to Windows 10 and it's hard to edit documents 8 hours a day with a white background, even with 25% screen brightness. Isn't there any other workaround for this? The HKEY_CURRENT_USER\Control Panel\Colors tweak works fine in Windows 7, 8 and 8.1, but doesn't seem to work in Windows 10. I don't really mind folder background, I would like for background color to be changed in MS Word and Excel applications and not a document-based background which appears on a printed paper, but a Windows based tweak to show for all windows (this includes folders and Office apps) the color silver in background. I'm guessing this is a theme based thing, that's why it's going back to white. I simply change the string for Window from 255 255 255 (which is white) to 192 192 192 (which is silver), but every time Windows restarts, it changes back to 255 255 255.

If the registry hack you are talking about is the HKEY_CURRENT_USER\Control Panel\Colors tweak, it's not working for me on Windows 10 Home 圆4.
