Product Version = NetBeans IDE 7.0 (Build 201104080000)
Operating System = Windows 7 version 6.1 running on amd64
Java; VM; Vendor = 1.6.0_20
Runtime = Java HotSpot(TM) 64-Bit Server VM 16.3-b01
The Netbeans button always gets duplicated in the taskbar, instead of just "extruding" the Netbeans pinned shortcut, and the running instance of Netbeans on the taskbar is unpinnable. I think this has been a problem since 6.8, also, this appears to be a Windows 7 x64 only issue as it works well on Windows 7 x32.
