⚠️ This is not a standard Microsoft Windows system DLL. It should not exist in C:\Windows\System32 unless an application installed it there incorrectly.
Because it is a C++ library, it relies on the Microsoft Visual C++ Redistributable. If the correct version of the VC++ runtime is missing or corrupted on the host machine, xplatcppwindows.dll will fail to load, causing the Teams application to crash on startup or fail to detect devices. xplatcppwindows.dll
