I am a complete noob using C++, i just want to re-compile an exploit.
I got the error:
you can not assign a value of type "const wchar_t *" to an entity of type "LPWSTR"

LPWSTRis defined aswchar_t*, versusconst wchar_t*. The error says you can't change a constant to mutable.

They've been cracking down on such practices in VS2017. You can get the old behavior with Project > Properties > C/C++ > Language, "Conformance mode" = No. Or use wcscpy_s() to conform.

The lpDesktop field is a LPWSTR (wchar_t*), not a LPCWSTR (const wchar_t *). A wide string literal is a const wchar_t[N] (where N is 16 in your example), which decays to const wchar_t *. You cannot assign a pointer-to-const-data to a pointer-to-non-const-data. That is what the compiler is complaining about.
To assign a string literal to lpDesktop, you need to cast it:
start_info.lpDesktop = (LPWSTR) L"WinSta0\Default";
Or better:
start_info.lpDesktop = const_cast<LPWSTR>(L"WinSta0\Default");
Otherwise, copy the data to a local non-const wchar_t buffer and use that instead:
WCHAR szDesktop = L"WinSta0\Default";
start_info.lpDesktop = szDesktop;
