'Personalize' in the contextual menu that appears.
Immediately, you will be taken to the Personalization settings screen in the Settings Windows application. Here you can quickly change the theme by clicking on a corresponding thumbnail in the 'Click a theme to apply' section at the top of the window.
This is also a great way for you to switch between light and dark themes on the operating system quickly when needed.
If you want to save a custom theme, view all available themes, or download new themes, scroll down and click 'Themes'.
In Windows 11, a custom theme is a combination of personalization settings related to shape, accent color, dark or light mode, mouse pointer style, and sound scheme. You can set each of these aspects individually in the respective settings.
At the same time, Windows 11 also provides quick links to each setting item at the top of the Personalization > Themes page. To set it up, simply click on the 'Background', 'Color', 'Sounds' or 'Mouse Cursor' items. Each link will take you to the respective settings page, where you can set those options.
If you've previously set up a custom background image in, or modified the color scheme, accent color, or mouse pointer style, there's an option that allows you to save your personalization pack as a custom theme. Adjust in Personalization > Themes. Just click the 'Save' button as shown below.
Then Windows will ask you to name the theme. Enter a name and click 'Save' again. Your custom theme will appear in the list of themes below.
You can expand the 'Current Theme' menu. In there, you will see thumbnails of each available theme arranged in order. In each thumbnail, you'll see a preview of that theme. Click on any thumbnail to select and the corresponding theme will automatically be applied.
To install new themes from the Microsoft Store, click the 'Browse Themes' button.
The Microsoft Store app will open to the 'Themes' section. If you want to download a free theme to your PC, click the 'Free' button located under the theme's name.
Alternatively, you can also purchase paid themes with your Microsoft account.
Wish you have a satisfactory interface.
