Customizing Shell UI Elements Beyond the Basics Task View & Experimental WinUI Styling

Windows has always offered ways to personalize the desktop experience—wallpapers, accent colors, and themes are the basics. But if you’re willing to dig a little deeper into the built-in Settings app and system menus, you can shape how the shell UI looks and feels beyond just the surface.

In this guide, we’ll walk through what you can do today with Windows 11’s built-in features to tweak Task View and explore the WinUI-based styling already integrated into the OS.

1. Task View Customization

Task View (accessible with Win + Tab) is your hub for multitasking and managing virtual desktops. While Microsoft doesn’t expose every possible tweak, there are still ways to refine its look and feel.

Steps:

Transparency & Background Effects
- Go to Settings > Personalization > Colors.
- Toggle on Transparency Effects.
- This changes Task View’s background into a blurred, acrylic-like layer, giving it a cleaner and more modern aesthetic.
Accent Colors in Task View
- Still under Settings > Personalization > Colors:
  - Enable Show accent color on Start and taskbar.
  - Pick a bold custom color or let Windows Automatically pick an accent color from your background.
- Your chosen accent carries into Task View highlights, buttons, and virtual desktop indicators.
Virtual Desktop Names & Wallpapers
- Open Task View (Win + Tab).
- Right-click a desktop and choose Rename.
- You can also set a unique wallpaper for each desktop by right-clicking the desktop thumbnail > Choose background.
- This makes Task View more personal and visually distinct.

2. WinUI Styling That’s Already Built In

WinUI is Microsoft’s design system for modern Windows apps—and parts of it are baked right into Windows 11’s shell. You don’t need external tools to see or tweak them; you just need to enable and adjust what’s already available.

Steps:

Mica Material & Transparency
- Enable Transparency Effects (same as above).
- This doesn’t just affect Task View—it also powers WinUI surfaces like the Start menu, Quick Settings, and File Explorer command bar.
Rounded Corners Everywhere
- Rounded corners in app windows and menus are a default WinUI styling choice. To see them consistently:
  - Use built-in apps like Settings, File Explorer, and Photos (they’re all styled with WinUI).
  - Apply Light or Dark mode via Settings > Personalization > Colors for best contrast with the rounded edges.
Dark Mode for Cohesive WinUI Look
- Go to Settings > Personalization > Colors.
- Under Choose your mode, pick Dark.
- WinUI’s dark styling is deeply integrated across system menus, Task View, and modern app shells.

3. Advanced Shell Personalization with Built-In Options

Beyond the flashy styling, Windows includes subtle personalization controls that influence how shell UI looks and feels.

Taskbar Behavior
- Settings > Personalization > Taskbar lets you choose alignment (center or left) and which system icons appear.
Start Menu Layout
- Adjust pinned apps or switch to More Pins or More Recommendations under Settings > Personalization > Start.
Themes
- In Settings > Personalization > Themes, you can save and switch between full theme packages (wallpapers, sounds, colors, and cursor styles).

These changes carry into WinUI surfaces automatically, keeping the shell cohesive.

You don’t need to dive into hidden flags or third-party apps to enjoy a more personalized, modern shell UI. By making smart use of built-in Windows features—from transparency effects and accent colors to virtual desktop wallpapers and WinUI dark mode—you can give your system a distinct look that feels polished and uniquely yours.
