I did consider writing about:

C:\Windows\System32\WptsExtensions.dll

but this phantom DLL has been documented all over the place, so let’s look at a different one:

C:\Windows\System32\XboxNetApiSvcExtHost.dll

It’s loaded by svchost.exe on Windows 11 24H2 and Windows Server 2022.

Windows Server 2022 launches ctfmon.exe during its start and this process’ DLL dependencies lead to an execution path that loads a phantom (non-existing) library:

C:\Windows\System32\LangDownloader.dll

So, you can drop your own and enjoy your stay!
