I don't understand how my post was vague, but OK... I'll try to make it clearer.
Go into the Windows Control Panel.
If your Control Panel is in "Category View", change it to classic view.
There should be a touchkit icon. I don't know the name of the icon
exactly, but it should be obviously related to the touchscreen.
Double-click on that icon and there should be a tab for calibration, I believe.
I also suggest reading this FAQ:

The link to the drivers in that FAQ are outdated. There is a link to the current drivers in this thread in the FAQ Emporium:
