Disable it and they're gone.

None of these worked for me. What did fix it, however, was unticking "Animate controls and Elements Inside Windows" under Control Panel, System, Advanced, Performance.
- Click START, right-click Computer and choose Properties
- On the left hand side, click Advanced System Settings
- Click Settings on the Performance category
- From the Visual Effects tab, untick Show shadows under windows
