With the launch of Windows 11, Microsoft has brought some visual changes to its desktop operating system, including adding noticeably rounded corners to windows, menus, and dialog boxes.While the new design update has been widely embraced by many users, there are some who prefer the more traditional angular look.

The good news is that it is possible to disable rounded corners in Windows 11, and this guide will walk you through three easy ways to do so.


1. How to disable rounded corners in Windows 11 using a third-party tool

Win11DisableOrRestoreRoundedCorners is an open-source tool on GitHub that helps you disable rounded corners on your Windows 11 PC.Since this tool modifies your computer's system files to remove rounded corners, it's a good idea to create a restore point before using it.

1. Go to the GitHub website to download the Win11DisableOrRestoreRoundedCorners tool.

2. Double-click the downloaded executable file to run it.

3. If you see the Microsoft Defender SmartScreen window, click More info and select Run anyway.

4. When prompted by User Account Control (UAC), select Yes.


Once you complete the steps above, a PowerShell window should appear with rounded corners disabled on your computer.Below is a glimpse of your window with rounded corners disabled.


Note that this tool will not disable rounded corners in the Start menu or some modern apps.If you want to revert these changes later, just run the downloaded EXE file again.

2. How to Disable Rounded Corners in Windows 11 Using Registry Editor

Don't want to use third-party tools?no problem.You can also disable rounded corners in Windows 11 by modifying the Windows Registry.However, the key is to proceed with caution, as modifying registry files without proper knowledge can be risky.

Before you proceed, consider backing up all registry files, just in case.Afterwards, disable rounded corners via Registry Editor using these steps:

1. Press Win + S to open the search menu.

2. Enter regedit and select the first result that appears.

3. When prompted by User Account Control (UAC), select Yes.

4. Navigate to Computer > HKEY_CURRENT_USER > Software > Microsoft > Windows > DWM.

5. Right-click the DWM key and select New>DWORD (32-bit) Value.Rename it to UseWindowFrameStagingBuffer.

6. Double-click the newly created DWORD and enter 0 in the Value data field.Then, click OK.

7. Restart your computer to apply the changes.


If you later want to reverse the above changes, repeat the previously mentioned steps, changing the value data of UseWindowFrameStagingBuffer to 1.

3. How to Disable Rounded Corners in Windows 11 via Device Manager

Another way to remove rounded corners in Windows 11 is by disabling the graphics drivers on your PC.However, some caveats must be considered.First, disabling the graphics driver will result in reduced display performance, reduced screen resolution, and deactivation of any visual effects.Second, it will also prevent you from running any graphics-intensive applications or games on your PC.

If you're okay with these tradeoffs, use these steps to disable rounded corners through Device Manager.

1. Press Win + X keys to open the Power User menu.

2. Select Device Manager from the list.

3. Double-click "Display Adapters" to expand it.

4. Right-click on your monitor driver and select Disable Device.


Once the graphics driver is disabled, you should see square corners on all Windows 11 windows and menus.If you later want to undo this change, just enable the graphics driver through Device Manager.

It's easy to disable rounded corners in Windows 11

Using a third-party tool is arguably the most convenient way to remove rounded corners in Windows 11.However, if you prefer to rely on native methods, you can use Registry Editor or Device Manager instead.

Disabling rounded corners isn't the only way to get the classic look of previous Windows versions.You can also use third-party tools like ExplorerPatcher to make Windows 11 look like Windows 10.
