* Properly implemented cleanup routines when injected into
applications other than Explorer
* Never EVER forget to specify a ThreadingModel for a COM object
in registry. That was the cause the DLL was making Microsoft Teams
crash on startup
* Do not free memory when the DLL is unloaded (DLL_PROCESS_DETACH)
and lpvReserved is non-NULL. It means the DLL is unloaded as the process
terminates, in which case all threads are dead, so it is not safe to call freeing
routines - let the operating system reclaim the memory on process exit
