Why Disable Rounded Corners?

Rounded corners in Windows 11 offer a sleek, modern aesthetic, but there are valid reasons to switch back to sharp corners.

Accurate Screenshots

Rounded corners can sometimes result in blurred edges or unwanted transparency in screenshots, which can be a problem for professionals.

Efficient Window Management

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

Customized Aesthetics

Some users prefer sharp-edged UI elements for a cleaner, more structured look that aligns with their personal or professional preferences.

Using Registry Editor

One way to disable rounded corners is by editing the Windows Registry, but be cautious as incorrect changes can cause system issues.

Warning: Editing the registry can be risky. Proceed with caution and back up your registry first.

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

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