How to disable "Rounded Corners" around browser web content in the latest Microsoft Edge update?

hirun 135

Hi,

As shown in the attached screenshot, the latest Edge update (Version 149.0.4022.52) has forced a white border/rounded corners around the browser window.

This UI element is very distracting. I have checked both Settings > Appearance and edge://flags, but the option to disable "rounded corners" has been completely removed from my version.

Questions:

Is there a Registry key to disable this border?

Why was the toggle removed from the settings?

Please provide a way to get back the square, edge-to-edge view. I want the web content to touch the browser edges like before.

Thank you. Screenshot 2026-06-07 003113

Microsoft do you really think it looks good in full screen mode? Please return the setting back, we need to disable this ugly frame

This is simply unnecessary and annoying. I love edge because it runs very smooth and feels integrated, but now Microsoft is making me migrate to a different browser. Please give the option to turn it off back, Microsoft.

关闭 Edge 设置→系统和性能→启动增强

修改目标字段末尾添加： --disable-features=msFeatureGroupNewLookAndFeelHoldout （注意：前面必须加空格，完整示例： "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --disable-features=msFeatureGroupNewLookAndFeelHoldout）

I wish they would let us choose instead of shoving change down our throats...

This is actually a reason for me to swap browsers, I hope MS adds an option to let us disable the rounded outer frame.

Always made wrong decision, always ignore users' voices, always indulge in self-complacency.

MicroSoft..... Why is this being forced on users with no way to opt out?

Plenty of people don't find this design attractive.

You already had a working solution — the flag that let us choose.

Removing that choice and imposing one look on everyone is exactly why you're getting so much backlash.

Bring back the option to disable rounded corners.

This ugly corner reminded me of IE where it has this annoying window frame.

I have been using Edge since beta and this is the last straw. I am switched to Vivaldi

~~Seemes to be fixed with Version 149.0.4022.62 - can anyone confirm?~~

~~Also the white line beneath the address bar when favourites bar is hidden also seems to be fixed.~~
Edit: I think it's the launch params only working when startup boost is disabled. I set it up yesterday but didn't get it working. Today it worked once when I thought it was .62 fixing it. I moved to Brave already anyway..

I disabled the rounded corners for a long time, but now that they are forced on me, I decided to try a different browser.

I have now switched to the Brave browser, which I already like very much. Thank you MS for pushing me away from Edge.

the first time when rounded corners were introduced, there was a feedback request triggert each time you deactivated the new look - and each time i voted against this new design. now it is forced with no clean opt-out mechanism. the '--enable-features=msForceNoRoundedCornerAndMargin' as startup parameter is now the last anchor and just a matter of time to vanish.

all these comments here are urging you, microsoft, to bring back a clean and sustaining opt-out mechanism which should in my opinion reside within the regular edge settings!

thank you for respecting community feedback.

I'm switching back to Google Chrome right now, just because of this. I absolutely hate this rounded corners feature with all my heart. And I don’t like being forced to accept things.

I am on that version, and the issue still exists.

This is false, the rounded border is still present even on 149.0.4022.69 and cannot be turned off.
