This solution doesn't seem to work. It says not supported on newer versions of windows.

The support page on the github says something about updating an ini but there are no inis and I don't know where to put this ini

Just because you've used it professionally, doesn't mean it's OK.

Run the installation file to install the RDPwrap dynamic link library (DLL). This software provides the necessary functionality to enable Remote Desktop from a Windows 10 Home system.

  begin
    if not Reg.OpenKey('\SYSTEM\CurrentControlSet\Control\Terminal Server\Licensing Core', True) then
    begin
      Code := GetLastError;
      Writeln('[-] OpenKey error (code ', Code, ').');
      Halt(Code);
    end;
    try
      Reg.WriteBool('EnableConcurrentSessions', True);
    except
      Writeln('[-] WriteBool error.');
      Halt(ERROR_ACCESS_DENIED);
    end;
    Reg.CloseKey;

So essentially the RDPwrap software subverts Windows 10 Home security to enable Remote Desktop Connections.

Even without disassembling their shim DLL, just their readme language and installer code doesn't give me warm fuzzies about this software's ability to survive legal scrutiny or a Microsoft audit.

Just like with backups, in my professional IT Admin opinion: if its expensive enough to need remote access, it's expensive enough to remote access the right way. There's plenty of free remote options on Windows that don't require monkey patching the core services and using a Home license professionally. Plus, if you have more than a few Windows installs, you probably want Group Policy anyways, so you're up to the pro license key for that anyway, plus the Windows Server license key(s) for the AD controller.

Yeah, windows is expensive when used professionally. If you need windows that badly deal with it or talk to your software vendors about getting Linux or Mac software.
