Before Windows 10’s May 2019 Update, Windows 10 had a dark Start menu, toolbar, context menus, and an action center with light-colored apps. With the May update light theme became the default and when you tried to turn the dark mode on it made the apps dark too.
If you liked the Windows OS theme before the update, you can get it by following this guide.
Get Windows 10 Dark Interface with Light Apps
Here’s how you can get Windows 10’s dark taskbar and start menu back:
First, go to Windows Settings by opening the “Start” menu and clicking on the “Gear” icon. Or press Windows key + I on your keyboard to launch the Windows “Settings”.
Click “Personalized” in the Settings window.
From the left pane, select the “Colors” option.
On the right-hand side of the window, click on the “Choose your color” drop-down menu. You will see that three choices are available; Light, Dark, and Custom.
Light: In this theme, you will see that everything is light-colored which includes application windows and a light taskbar, Start menu, and action center.
Dark: As the name suggests that it’s a Dark theme that turns everything dark, from app windows to the Start menu, taskbar, and action center.
Custom: In this theme, you can custom select the theme of your choice. It allows you to choose a combination of dark and light themes. Customizing the Windows 10 OS theme, you can get the combination of your choice where you can have a dark taskbar and light application windows that look exactly like Windows 10 old theme.
Select the “Custom” option from the drop-down menu.
Two new options will appear below the “Choose your color” menu.
Select “Dark” for “Choose your default Windows mode”. And “Light for “Choose your default app mode”.
Close the Windows Settings after making the changes and you will notice that the taskbar is now in dark color whereas application windows have light color just how Windows 10 used to look.
