I've recently installed Visual Studio and Visual Studio Code and the two .dll files are left in my C:\
folder. Both are signed by Microsoft. Is there any reason for them being there? Can they be moved or deleted?
The files are:
C:\appverifUI.dll
C:\vfcompat.dll
Both Visual Studio and Visual Studio Code are the latest releases from the official site.
I assume they are left from the installation process and should have been moved/deleted by the installer, but I'm not sure.
I found both DLLs after I added the C++ development tools to my Visual Studio installation. Before I only had the .NET desktop development environment set-up on this machine. The Microsoft documentation only states those DLLs are used to detect OS compatibility issues. I am running Windows 11 here and just deleted them using local administrator privileges without any obvious effect in Visual Studio C++ development set-up. So just give the deletion a try :) If Visual Studio is running on the system, it should not be a production environment anyhow.
