    Windows 7, 64bit
 Using Qt 5.3.1 with MinGW 4.8.2 (pre-compiled bundle from http://download.qt-project.org/official_releases/qt/5.3/5.3.1/qt-opensource-windows-x86-mingw482_opengl-5.3.1.exe)

        3d24906394049f34e471f300a87396255b523245 (5.4, 2.10.3014, 5.4)
The QWinJumpListCategory "tasks" (QWinJumpList::tasks()) doesn't show up.
The "recent" catgory seems to work fine.
Not sure about the "frequent" category but I don't know what's the difference between "recent" and "frequent" anyway. 
Steps to reproduce
Compile and run manual test "jumplist" (5.3/Src/qtwinextras/tests/manual/jumplist)
