Having passed the release candidate (RC) stage, the release to market (RTM) version of Windows 7 is now available for IT professionals within the Microsoft network.
Those holding an MSDN subscription can get the English-language RTM of Windows 7 while other language version will be made available from 1 October.
Yochay Kiriaty said on the official Windows Blog: "Make sure you get them all today to start testing your applications, and to make sure your applications are ready for Windows 7 RTM.
"Now is the time to work on your applications to make sure they are Windows 7 compatible."
He added that new Windows 7 features including the Sensor and Location Platform, Taskbar, Libraries, Multi-Touch, the new Graphics APIs and the Windows Ribbon are now ready for developers to integrate into applications.
The Windows 7 Training Kit for Developers has been updated to help with this and is for both native Win32 C++ developers and .NET developers.
