Change visible application name (Windows)

I am looking for a way to change my application name (that appears on right click on Windows 7 taskbar):

To something more informative like:

开发者_如何学编程How do I do that? I am using: Qt 4.7 (MinGW), Windows

I have found some info about using certificates and signing executables, but I am not sure if it is what I need. I know how to change icon. Thanks in advance.

From 5 minutes of experimentation it seem to be coming from the FileDescription field of the VERSIONINFO resource. It also seems like Windows is caching these values based on filename; I had to rename the .exe file each time I changed the resource for the changes to show up.
