To customize the taskbar in such a way, you’re going to need a third-party app. This is how you can add some curvature to your Windows 11 taskbar with RoundedTB.

How to Download and Install RoundedTB

RoundedTB is a freely available Microsoft Store app with which you can add both curved corners and margins to Windows 11’s taskbar. Because it’s an MS Store app, you’ll need to be signed in to a Microsoft account to download it from there.

If you don’t have a suitable account to sign in to, you can set up one on the Microsoft account website. When you’ve set up and signed in to an MS account in Windows 11, you can download and install RoundedTB as follows.

Open the Microsoft Store from the Start menu’s pinned app section and search for RoundedTB, or visit RoundedTB’s Microsoft Store page directly. Click the Get button to download and install RoundedTB. After installing it, you can click an Open button on the RoundedTB MS Store page to launch the app. Alternatively, enter the keyword RoundedTB in Windows 11’s search box to find and open the app from there.

How to Change the Taskbar’s Corner Radius and Margin

Now you can have some taskbar customization fun with RoundedTB. To add some curve to the taskbar, drag the slider for the Corner radius bar to the right. Applying a maximum curve setting of 48 will add rounded corners to both sides of the taskbar as shown in the snapshot directly below. Click Apply to save any selected options.

To add some margin to the taskbar, drag the Margin bar’s slider slightly to the right. Doing so actually reduces the width of the taskbar by removing pixels from the top and bottom of it. If you drag that bar’s slider to the far right, the taskbar will completely disappear. So, it’s best not to set that option any higher than about nine as shown directly below.

How to Apply RoundedTB’s Advanced Options

RoundedTB includes more options you can access by clicking the Advanced button. Dynamic mode is the most interesting advanced setting. Selecting and applying the Dynamic mode option turns the taskbar into something akin to the macOS Dock. That setting strips the width of the taskbar down to the number of icons it includes like in the screenshot directly below.

Selecting the Dynamic mode option on its own will remove the system tray clock and area. However, you can preserve the clock by selecting the Show system tray area option. Alternatively, select the Show system tray on hover option, which enables you to view the tray area by moving the cursor over it.

Just below those system tray options, you’ll notice a TranslucentTB compatibility checkbox. TranslucentTB is kind of like a RoundedTB sister app that enables you to add transparency to Windows 11’s taskbar. Our guide on how to make the taskbar transparent in Windows 10 article provides further details for that app.

Selecting the TranslucentTB compatibility option will enable that app’s taskbar transparency effects to work with RoundedTB.

When you’ve finished tinkering with the taskbar, you can close the RoundedTB window. RoundedTB will still be running in the background after exiting its window. You can completely close the app by right-clicking its system tray icon and selecting Close RoundedTB. However, closing the app also removes its taskbar customization.

Enhance the Taskbar’s Aesthetic Appeal With RoundedTB

RoundedTB is a nifty customization app for enhancing the taskbar’s aesthetic appeal in Windows 11. You can add altogether more stylish rounded corners to the taskbar with RoundedTB. Users who prefer the macOS Dock to the Windows taskbar will also appreciate its Dynamic mode option.
