If you do "Run as administrator" then it's elevated, but there's a special permission called "uiAccess" that the process can only get if these three conditions are met:

  • UAC is enabled
  • DF is signed with a valid code-signing cert (it is)
  • DF is installed and running from either "Program Files" or "Program Files (x86)"

In your case, it's the first one that's preventing it from obtaining uiAccess and there's no way for us to work around that.


Well, it seems to be working now.

@JesusPedrosa1 We've released a new beta with some changes that might help here, can you try it out and let me know if the issue persists?


Will test it and report back. So the problem is that DisplayFusion is not running elevated if UAC is disabled, even if my user is an Administratror.

@Jesus: We have a fix for your issue coming in 10.1 Beta 3. It will work when switching from Win32 apps to any app, but we can't work around the issue for switching from UWP apps. Windows won't allow us to do the focus change if the currently focused app is a UWP app when it's not running elevated with UAC.


Amazing.

@Nekron: You've found the workaround for your issue. Windows de-registers app windows that don't have buttons on the Windows taskbar, so when DF is set to "All taskbars show relevant" and a window is on the second monitor, its button is removed from the primary and Windows will no longer show it in Alt+Tab. ]]> RE: Windows 11 Alt+Tab stops displaying apps on the secondary display when using DisplayFusion https://www.displayfusion.com/Discussions/View/windows-11-alttab-stops-displaying-apps-on-the-secondary-display-when-using-displayfusion/?ID=2791c8c7-7354-41da-8f12-c51267e1267c#26 Mon, 24 Apr 2023 14:56:54 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alttab-stops-displaying-apps-on-the-secondary-display-when-using-displayfusion/?ID=2791c8c7-7354-41da-8f12-c51267e1267c#26 DisplayFusion

Any solution for latest stable w11? enabling UAC does not resolve the issue on winver 22621.1555


I don't think we have the same problem. Mine is that selected app when doing Alt+Tab does not come forward, its button flashes on the taskbar and that's it.

The best I can suggest is for you to try VistaSwitcher. It's very configurable, works great and it's faster than DF's Alt+Tab. ]]> RE: Windows 11 Alt+Tab stops displaying apps on the secondary display when using DisplayFusion https://www.displayfusion.com/Discussions/View/windows-11-alttab-stops-displaying-apps-on-the-secondary-display-when-using-displayfusion/?ID=2791c8c7-7354-41da-8f12-c51267e1267c#25 Mon, 24 Apr 2023 14:45:11 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alttab-stops-displaying-apps-on-the-secondary-display-when-using-displayfusion/?ID=2791c8c7-7354-41da-8f12-c51267e1267c#25 DisplayFusion

Workaround i found to be "working" is to go to registry to this location HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer and then add dword AltTabSettings with value 1 and reboot pc, it chances alt tab to old one without window previews but at least it shows apps on all screens not just ones from default one


That solution doesn't work anymore in Insider builds, so it won't work in future Windows releases either.

Nope. I don't have any other 3rd party window management app. And if I Exit DisplayFusion both Win11 and classic Alt+Tab work ok, why would that be?

I tried shutting down every single program that was loaded in memory, even basic stuff like mouse drivers, and it didn't make any difference...
