RDP Wrapper Library by Stas'M

The goal of this project is to enable Remote Desktop Host support and concurrent RDP sessions on reduced functionality systems for home usage.

RDP Wrapper works as a layer between Service Control Manager and Terminal Services, so the original termsrv.dll file remains untouched. Also this method is very strong against Windows Update.

This solution was inspired by Windows Product Policy Editor, big thanks to kost :)

Attention:
It's recommended to have original termsrv.dll file with the RDP Wrapper installation. If you have modified it before with other patchers, it may become unstable and crash in any moment.

Information:
• Source code is available, so you can build it on your own
• RDP Wrapper does not patch termsrv.dll, it loads termsrv with different parameters
• RDPWInst and RDPChecker can be redistributed without development folder and batch files
• RDPWInst can be used for unattended installation / deployment
• Windows 2000, XP and Server 2003 will not be supported

Porting to other platforms:
• ARM for Windows RT (see links below)
• IA-64 for Itanium-based Windows Server? Well, I have no idea :)

Building the binaries:
• x86 Delphi version can be built with Embarcadero RAD Studio 2010
• x86/x64 C++ version can be built with Microsoft Visual Studio 2013

• RDP works, but termsrv.dll crashes on logon attempt - Windows Vista Starter RTM x86 (termsrv.dll 6.0.6000.16386)
• If Terminal Services hangs at startup, try to add rdpwrap.dll to antivirus exclusions. Also try to isolate RDP Wrapper from other shared services by the command:
sc config TermService type= own
• RDP Wrapper Installer can be removed by AVG Free Antivirus after reboot - add it to exclusions.
