When using on 22000.1 ,the program says pattern not found

As the title states, is there any way you could port rounded corners to Windows 10? That'd be a great addition!

It'd be awesome to have this be installable with winget install valinet.DisableRoundedCorners just like we can currently with winget install valinet.ExplorerPatcher

All windows have square corner except the start menu, can you get rid of the rounded corner on the start menu?

EN:
When Win10EnableRoundedCorners? XDDD By the way, I'm romanian too XD

I run exe and then decided to remove rounded icons run exe again and PC has frozen. Now when I boot up it's just infinite loading?

Any suggestions how to repair it?

As in title, I just upgraded to 10.0.22621 Build 22621 and Win11DisableOrRestoreRoundedCorners no longer works.

Hi all, I was using DisableRoundedCorners and then updated to newer version and when I ran the .exe file again it said "Unable to restore DWM".Is there any fix ?

can you fix this? it might improve it

Hi, after great success on several pc's. i wanted square corner on my upgraded win10 machine.

After installing win11 , and executing Win11DisableOrRestoreRoundedCorners my main display of 3, went black, reboot same result.
so i restored uDWM.dll, and i got graphics again.
so after updating win11 to latest win11 Version 10.0.22621.1702
uDWM.dll ver 10.0.22621.1485

Executing Win11DisableOrRestoreRoundedCorners.exe, same result black main screen, with graphics on the 2 other displays.
anything i can try, or log?
after restoring uDWM.dll and rebooting all screens are working again.

please advice :)

This program has no effect on the latest versions of Windows 11.

I would advise an update to rectify this.

Basically the problem is that, when I drag a window around the screen, the background would turn black. Taskbar not influenced, just the other windows and the wallpaper (with all the desktop icons). Then the screen would return normal after dragging.

This issue only happens with some certain windows. For instance, dragging task manager and registry editor does not trigger this, but Microsoft Edge does, and so does terminal and many other apps.

To add more details, I am using the dev channel Windows 11 pro, with version 10.0.23545.1000.

What about the maximize square that was added in Windows 11? How do I disable it?

There is another way to disable the rounded corners without patching the binaries: win11-toggle-rounded-corners

Will this patch work properly on ARM versions of Windows 11? That’s what I’m running on my Mac. I don’t want to try without asking in case it downloads the wrong DLL.

Hello, great work, I was waiting for such solution :)

Few comments:

1. restore from backup doesn't work on 22000.258 - dwm is crashing and can't run properly, restart doesn't help, black screen with spinner, from the login sound I can say that system starts properly, just the window manager can't start.

2. can you make it work offline? what's about this symbol downloading, is this really necessary?

3. is it possible to make buttons and menu selection squared again as well (I mean classic win32 applications, not modern ones)? it's stays rounded for now

4. after disabling rounded corners explorer menu has white border when dark theme is enabled, it should have taken the menu border from accent color

When I opened the exe file for a second time (to disable it), my entire desktop turned black. But I think it's just a window, because when I press that button on the right of the taskbar that minimizes all windows, my desktop is back to normal. I have no idea how to fix it, I've tried closing some exe files with Task Manager that I thought might be causing it, but nothing worked. I'm pretty sure it's not a different app causing this, because it happened right after I opened Win11DisableOrRestoreRoundedCorners.exe.

I feel like the windows 11 rounded corners disabled for the Start menu, quick settings and notification centre look strange and would prefer to have a option where you could only make the application rounded corners disabled for i.e. File Explorer, Device Manager, Photos app etc

I only encountered this problem:

in Paint.NET (version 4.3.12 but I dont think its a version problem or even paint.net) the circle representing the brush cursor in the software has changed from circular (normal) to squared (precisely a square)

Im sure of this because I dont use additional brushes in paint.net

this tweak is a great change (but not this issue), I hate the round edges on the windows

After the latest patch (KB5006674) corners reverted to round and the program now reads "Unable to restore DWM."
Please advise accordingly

EDIT: Fix Found, need to delete the .bak manually and the patcher works properly.
Btw, thanks for your great work

For MFC apps and win32 apps,buttons and textboxes have rounded corners.
For UWP flyouts like the "restored Windows 10 network" , buttons have rounded corners.
Is there a way to fix this?

Dear Valinet
How we can Enable Again Rounded Corners ?
Thanks you.

1. Does Translucent TB work with ExplorerPatcher?
2. Can you add an option to enable the search bar for the Windows 10 taskbar in ExplorerPatcher?

i ran this executable a while ago
forgot about it

ran SFC /scannow
which restored rounded corners

and now when i try to apply the patch again, its trying to restore it.

As of today's latest 11 updates, it appears this approach no longer works? I receive the error "Unable to restore DWM"

Not sure if this is intended or not, but there is a white outline surrounding most old-style context menus after applying the patch. Could it be removed?

The windows version is

• w11 22H2;
• OS Build 22621.2428;
• Experience Windows Feature Experience Pack 1000.22674.1000.0

If error occurs, run this.zip

Pc showing a black screen with my curser after trying to disable. help

When you right click an icon on the taskbar rounded corners remain enabled.

it didn’t restore properly and it broke my whole installation.

Successfully changed DACL.
Unable to prepare for replacing system file.

This error showed up what do i do also there is two of the backups?!

Edit: If I run the exe again it kills dwm process but There is still Rounded corners I tried deleting the backups the
uDWM_win11drc.bak this file can be deleted, and i deleted it still same
uDWM_win11drc.bak1 I cannot delete this one tho

edit : I ran sfc /scannow
and chkdsk
But still the same

Moonique from the Virtual Customs forum has managed to restore the window frames and title bar so that the theming in those areas is possible, but had to replace several Windows 11 files with Windows 10 files.

Is it possible to do that or integrate that feature into this patch?

With the latest cumulative update (KB5006746) bringing the Windows 11 build to 22000.282, the DWM file has been updated again and it lost all its sharp corner goodness!

This is the console output I'm getting:

Unable to determine function address.

Can you please fix it?

Hi Valentin-Gabriel,

firstly I want to thank you for this plugin.

Personally I don't have problem with rounded windows, I've just decided to use it order get rid of the weird, annoying padding in old-style context menus. It's default behavior when you change back context menu so it is Window's bug, and this is be more feature request rather than reporting a bug. Find please the screenshot bellow:

I have set back rounded corners, but with plugin installed it is the same obviously. I am wondering how complex it would be to fix that problem within your plugin.

Thank you in advance for considering it.

Hello,

I have an annoying problem. In build 22000.556, the previously activated tool named "Win11DisableRoundedCorners" stops working. Enabling this tool will result in the error that the old DWM cannot be restored. Can it be fixed without damaging the DWM (which restores Windows Basic, which causes the system to stop working properly)?

Greetings,

Hey!

I was thinking if it'd be possible to remove the win11 borders? I'd like to just keep the window look like it's maximized.

Maximized:

Normal:

That whiteish 1px border is triggering me very much, do you think you could get rid of that as a feature in this project or maybe a separate project?

I ran sfc /scannow, but now i cant go back to box corners, all i ask for is a way to force it to install or uninstall, regardless of the state of dwm, like a command line argument:

Win11DisableOrRestoreRoundedCorners.exe --restore
Win11DisableOrRestoreRoundedCorners.exe --patch

Every time i run the patcher it tells me it cant restore dwm
(it's already original, and it doesn't have the perms to do so)

Flawless if it weren't for the fact that the windows that appear when alt-tabbing still have rounded corners.

Ex: https://i.imgur.com/kymfvF0.png

Hello, When I open the executable It shows an error that says, Unable to restore DWM. Can anyone help me with this error?

when this is installed, the nvidia driver installer doesnt have permissions to restart the dwm.exe process so the install fails

Do you think you could find the right function to patch to make window borders thicker?

If you're to run the sfc /scannow command in the command prompt or terminal with the modified uDWM.dll installed it will be detected as a corrupted file, and the original uDWM.dll will automatically be restored on the next system start up- now when you try disable the round corners again the prompt outputs an error that states it failed to restore.

Ah, sorry I just realised this was old news! I tried the work-around of deleting uDWM_win11drc.bak and magic my problem is gone :-)

G'day Team,

I downloaded this App a couple of weeks back to get rid of the puerile Rounded Corners from Forms and Dialog Boxes in Windows 11. All good then.

But this afternoon Windows Update installed 10.0.22000.918 and the Rounded Corners were back.

And now running your App gets the "Unable to restore DWM" consistently and I am stuck with the "kiddie-proof" Windows.

Cheers, Paul

When I run the executable as administrator from the file explorer I get the following error.

Function address is: 0x227a4
Unable to find pattern in file.

For the sake of it, I copied the "uDWM.dll" file that was outputted alongside the executable in my Downloads folder & pasted\overwrote it in the "C:\Windows\System32" directory using the copy command in the WinRE command prompt after locating my Windows drive letter, and no changes were made to the corners upon continuing to Windows 11 afterwards.

I stumbled across this preference in PowerToys. If you just want to disable rounded corners and you don't mind using FancyZones, this is by far the easiest (official?) way to do it:

win11 21H2
ver:22000.708

how can i bring back the round corners? its bugging some uwp apps, mostly snipping tool and notification center
