By request, here is a portable version of Windock. 

It was minimally modified so here are some things you should know:

  • Without the installer, you need to make sure the machine has Microsoft .Net framework 4.0 and c++ 2010 redistributable installed.
  • The "Start with Windows", "Enable drag from Maximized", and "Enable Snap Sizing" check-boxes will not carry over their settings to another machine (or user). 
  • Windows' own Aero Snap feature will be disabled upon WinDock's execution. You can enable it again through the control panel. (Google it if you don't know how.)
