When you have Windows 7 and open a program, the program temporarily pins to the taskbar. When it does, the length of the icon and wording showing on the pinned program is 1 1/2 inches (3.81 cm). When I changed the registry line item, the length of the icon, etc. showing on the pinned program permanently changed to 9/16th inch (1.42875 cm). If you compare my screenshots in post 5 above you can see the difference. Unfortunately this isn't something where you can just click a square or pick an option. I wish it was that easy. Thanks for trying. I hope this explains it because I don't know how better to explain it.
