How to Disable Windows 11 Round Corners: 4 Easy Methods!

This guide provides four methods to remove the rounded corners in Windows 11, restoring the classic square-edged look. While the rounded corners offer a modern aesthetic, some users prefer the sharper look for reasons including improved screenshot accuracy, easier window management, and personal preference.

Why Ditch Rounded Corners?

Rounded corners, while modern, present some drawbacks:

• Sharper Screenshots: Avoid blurry edges and unwanted transparency in your screenshots.
• Improved Window Organization: Square corners facilitate precise window alignment and stacking, boosting multitasking efficiency.
• Clean Aesthetics: A preference for a cleaner, more structured interface.

Method 1: Registry Edit (Use with Caution!)

Modifying the Windows Registry can disable rounded corners. Proceed with extreme caution, as incorrect edits can damage your system.

1. Press Win R, type regedit, and press Enter.

2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\DWM.

3. Locate RoundedCorners. If absent, create a new DWORD (32-bit) value named RoundedCorners.

4. Set its value data to 0.

5. Restart your computer. This method's effectiveness varies across Windows 11 builds.

Method 2: High Contrast Mode (Temporary Fix)

Enabling High Contrast Mode disables several UI elements, including rounded corners. This is a temporary solution affecting overall visual appearance.

1. Open Settings (Win I).
2. Go to Accessibility > Contrast Themes.
3. Choose a High Contrast theme.

4. Apply the changes.

Method 3: Third-Party Tools (Recommended)
