How to Get Rid of Microsoft Edge's Rounded Borders After the Latest Update

#microsoft #tutorial #ui #ux

Microsoft Edge now enables rounded window borders by default starting with version 149 and later. Unfortunately, Microsoft has also removed the related flag from edge://flags, so the setting can no longer be disabled through the browser's experimental features page.

If Microsoft Edge is your default browser and you're not a fan of the rounded borders (like me), follow the steps below to temporarily get rid of them. I'll keep this article short and straight to the point.

NOTE: Unfortunately, this is not a clean or permanent solution. It is only a temporary workaround. If you'd like Microsoft to provide an official option to disable rounded borders, I request sharing your feedback and upvoting the related request on the Microsoft Feedback Portal: https://feedbackportal.microsoft.com/feedback/idea/7e9fa301-22d1-f011-ad8f-7c1e52f38cbc

How to Use Microsoft Edge Without Rounded Borders on Windows

1. Kill All Microsoft Edge Processes

First, close all running Microsoft Edge processes. You can do this manually through Task Manager (Ctrl + Shift + Esc) by locating every Microsoft Edge process, right-clicking it, and selecting End Task.

Alternatively, open Windows Terminal or Command Prompt and run the following command:

tasklist /FI "IMAGENAME eq msedge.exe" 2>NUL | find /I /N "msedge.exe" >NUL
if "%ERRORLEVEL%"=="0" (
    echo Killing msedge.exe...
    taskkill /F /IM msedge.exe
) else (
    echo msedge.exe is not running.
)

2. Launch Microsoft Edge Without Rounded Borders

Open Command Prompt and launch Microsoft Edge using the following command:

"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --enable-features=msForceNoRoundedCornerAndMargin

And voilà! Microsoft Edge should launch without the rounded borders.

Important Caveat

This workaround only remains active for the current Edge process.

If you close all Microsoft Edge windows and later launch Edge normally (for example, from the taskbar, Start menu, or desktop shortcut), the rounded borders will return. To continue using Edge without rounded borders, you'll need to launch it again using the command above.

To make things easier, you can save the following script as a batch file (for example, launch_edge_no_rounded_borders.bat) and use it whenever you want to launch Edge without rounded borders:

@echo off

REM Find and force-kill all Microsoft Edge processes
tasklist /FI "IMAGENAME eq msedge.exe" 2>NUL | find /I /N "msedge.exe" >NUL
if "%ERRORLEVEL%"=="0" (
    echo Killing msedge.exe...
    taskkill /F /IM msedge.exe
) else (
    echo msedge.exe is not running.
)

REM Launch Microsoft Edge without rounded borders
start "" "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --enable-features=msForceNoRoundedCornerAndMargin
