How to Disable Rounded Window Corners in Windows 11

Windows 11 introduced a sleek, modern look with rounded window corners, giving the OS a fresh aesthetic. However, for some users who prefer a more minimalist and clean design, these rounded edges may feel unnecessary. This article explores methods to disable rounded corners in Windows 11.

Method 1: Disable Hardware Acceleration

Rounded corners in Windows 11 rely on hardware acceleration. Disabling it might help remove these rounded effects:

  1. Open the Control Panel and go to the System section.
  2. Find the Advanced System Settings tab, then select Settings under the Performance section.
  3. In the pop-up window, uncheck the options for “Smooth edges of screen fonts” and “Show window shadows”.

Disabling these options may remove the rounded effect in some windows, but it doesn’t always apply to all elements.

Method 2: Edit the Registry

This method involves modifying the registry, so it’s recommended to proceed carefully and create a restore point first:

  1. Open the Registry Editor by pressing Win + R and typing regedit.
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM.
  3. Create a new Dword (32-bit) value named RoundedCornersEnabled.
  4. Set this value to 0 to disable rounded corners.
  5. Restart your computer to apply the changes.

This method may not work on all versions of Windows 11, but it has been effective in removing rounded corners on some builds.

Method 3: Use Third-Party Utilities

There are third-party programs available that provide greater customization options for Windows 11. Tools like WinAero Tweaker or ExplorerPatcher can help disable rounded corners and other visual elements.

  1. Download WinAero Tweaker from the official website and install the program.
  2. Under the Appearance section, find the option to disable rounded corners and apply the changes.
