The borders on Windows Vista have been set large by default so their new graphics and design can be shown off, but if you don’t like the large borders you can adjust the size of them;

  • Right click your desktop
  • Click personalize
  • Click windows color and appearance
  • Click advanced
  • From the dropdown select border padding
  • Change the size (I suggest 2)
  • Click OK
  • Done
