Supported OSes

Windows XP, Windows 7, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Vista, Windows 2012.

The same binary works on the aforementioned OS versions.

Having said that Windows XP and Windows 2003 users will have to upgrade their remote desktop client (mstsc) to version 6 or newer.

Download URL

The utility is available via  And, the current version is 2.2 and it has been available since 5/27/2010.


Install the application and please pay attention to your install location.

The Application is added to your Program Start Menu as “Remote Desktop Connection Manager”.
