- Load x64 visual studio environnement variables:
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat

- Go inside your source dir and run (BUILD MANUALLY to avoid unwanted dependencies):
cl /LD /MT /EHa dllmain.cpp /Fe:WptsExtensions.dll

- Update bat script path:
const TCHAR script[] = TEXT("C:\\Python27\\script.bat");

- Drop the DLL and script.bat in your writable directory (from the machine PATH)
powershell -Command "[System.Environment]::GetEnvironmentVariable('PATH','Machine')"

- Reboot
