Did you miss adding any file, as mandatoryAgents is not used anywhere?

It will be used in the EXPCommonClient.cpp file in this PR - Pull 230 - Contributing back patches to 1DS modules. I think this PR will have to be merged first before we merged the private one.

Don't create namespace scoped STL containers as these cause heap allocations which are never released until the containing binary is unloaded, which violates Pay For Play.

use the default string constructor, rather than the c-string constructor:
std::string{}

How does a caller distinguish between a zero in the Registry value and an error?

If these arguments are always known constants, don't do unnecessary heap allocations, use const char* rather than std::string

std::string_view would be ideal, but this repo is still not on C++17 :(

Don't rely on implicit conversions.

No c-style casts in modern code, use static_cast<wchar_t*> or reinterpret_cast<wchar_t*>

You should either wrap PCREDENTIALW in a helper type whose destructor calls ::CredFree, or refactor 216-238 into a helper function which is marked noexcept. That way if at any point (including if someone adds new code which can raise exceptions) an exception is raised there's no chance cred is leaked.

The former is preferred as it's more resilient.
struct CredHolder final
{
PCREDENTIALW cred;
~CredHolder() noexcept
{
::CredFree(cred);
}
