Changing background in gnome also changes it in windows

Changing background in fedora also changes it in windows which is very annoying how to fix

I’m not sure I understand what you mean. Can you please clarify? Do you mean windows as in a window of an application (which is confusing because windows don’t have a background) or a Windows OS installation (dual booting for example—which is also confusing because changing user settings like background in one OS does not affect another OS in anyway)?

That is seriously strange.

What if you change it in Windows? Will it also change in Fedora?
