Is Windows screwing up your background colors, e.g. Files Explorer is black, your taskbar is white

[progree]

and it's driving you crazy, and you followed advice you found online to go to Windows Settings (WindowKey i or Windows Start leftside menu) and choose Personalization -- > colors - > and change from dark to light or choose custom colors and screw around with the dark and light settings

and it changes things but about a minute later, it reverts back or to something else?

I recently (Oct 16) did a Windows update and a PowerToys update and that's when the problem started

It turns out that PowerToys has a new app, called Light Switch,

Windows 11 can now automatically switch between light and dark modes. How to do it, Mashable, 10/16/25

Light Switch is a new one packaged with PowerToys 0.95, as outlined in a Microsoft blog post.

I found it 10/18/25 - Light Switch was On, I turned it Off.

Back to Personalization -> Colors -> I have it set to Dark, because I can't stand my taskbar being white. But File Explorer background is black, arggh, but I can live with it.

Anyway, my taskbar has been staying black as desired. If it continues to be stable, then I will explore Personalization -> Colors -> Custom Colors and fiddle around with the 2 light/dark settings to see if I can get File Explorer white, while keeping the taskbar black.

By the way, my system is Windows 10, and yes, I know that starting October 14, no more updates, so I'll have to sign up very soon for the updates extension (for a year).
