We just created and uploaded an evaluation version of Q7Goodies. This version has the same features as the full one but it works only for 30 days and appends the 'Q7Goodies' string to window title, jump list entries, taskbar thumbnail title, etc.
The evaluation version contains dynamic and static libraries for both: Microsoft Visual C++ and MinGW (QtCreator). There are also two demo applications and their source code. The header files are self-contained, it means that you don't need to install the Windows 7 SDK.
Ok, where to download it? Just go to the demos section.
