Why Should You Disable Rounded Corners?

While rounded corners give Windows 11 a modern look, they might not be ideal for everyone. Here are some benefits of disabling them:

More Accurate Screenshots

Rounded corners can cause blurred edges or unwanted transparency in screenshots.

Better Window Stacking

Square corners make it easier to align and stack windows neatly, improving multitasking.

Enhanced Aesthetics

Some users (especially perfectionists like me) prefer sharp-edged UI for a cleaner and more structured look.

Using a Registry Hack

One way to disable Windows 11's rounded corners is by modifying the Windows Registry.

However, be cautious—editing the registry incorrectly can cause system issues.

Step 1 Press Win + R , type regedit, and press Enter⏎ .

Step 2 Navigate to the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\DWM

Step 3 Look for RoundedCorners (if available). If not, create a new DWORD (32-bit) value and name it RoundedCorners.

Step 4 Set its value to 0.

Step 5 Restart your PC.

Using High Contrast Mode

Another workaround is enabling High Contrast Mode, which removes some UI effects, including rounded corners.

Step 1 Open Settings ( Win + I ).

Step 2 Navigate to Accessibility > Contrast Themes.

Step 3 Select one of the High Contrast Themes.

Step 4 Apply the changes.

Using Third-Party Tools

There are multiple third-party tools that can remove Windows 11's rounded corners. Here are three options:

• 1. ExplorerPatcher
• 2. Win11DisableRoundedCorners
• 3. Windhawk disable-rounded-corners Plugin
