[Bug]: WVDH Window Appears In Alt+Tab

[ptoshkov]

What happened?

Hello! Thanks for making the wonderful WVDH. I use it a lot.

I have noticed that when using WVDH 2.0, a window called "Windows Virtual Desktop Manager" appears when alt+tab is pressed.

Additional information: the issue does not occur when using WVDH 1.7.

WVDH Version

2.0

Windows Version

Windows 11 Pro 24H2 build 26100.4351

Windows 11 Pro 24H2 (26100.4770) - same inconvenience

Came to check if this was hopefully fixed but unfortunately it still happens.

I created this small AutoHotKey launcher script to launch the program and hide it from Alt + Tab /. Win + Tab

Run, "C:\Program Files (x86)\Windows Virtual Desktop Helper\WindowsVirtualDesktopHelper.exe"
Sleep, 2000 ; Waits 2 seconds for the program to fully start
WinHide, Windows Virtual Desktop Manager
ExitApp ; Exits the script after hiding the window

I placed the AHK script in my startup folder so it runs on startup.

Thanks for this - I noticed this popped up as well recently. Don't know what windows changed but I am sure I can fix it...
