Switching to dark mode
Step 1: Go to Settings. You can either type it into the Windows search bar, or click the gear icon in the Start menu.
Step 2: Head to Personalization, which features an icon of a paintbrush over a computer monitor.
Step 3: When the window opens, click Colors in the lift-hand sidebar.
Step 4: Scroll to the bottom of the first section and look for an option that says, “Choose your app mode.” Here, you will have two options: Light and Dark. Check the bubble beside Dark.
Step 5: That’s it! Your windows should now be black, though, your background image will remain largely the same.
