In the world of computers, the term “Pinned” is a lot like the physical act of pinning something up on a cork board. In our case, it refers to items within a window that are kept in the same place for easy access. Programs, applications, web sites, etc. can all be stuck up in a menu and accessed at your leisure depending on the program. The bottom section of the Start Menu is reserved for frequently used programs, or programs that I use on a regular basis. Though this may sound the same as a pinned menu, the items on the list change dynamically based on what I've been apt to do lately. So if I've been using the calculator a lot, it's icon will show up, but if I stop using it for awhile and make use of something else, that icon will show up. Get the point? :) ~Andrew
For Example:
The Windows Vista Start Menu is divided into two sections. The top half of the menu is reserved for pinned items. Because I use Photoshop, Illustrator and Dreamweaver almost every day, I keep them pinned; making them accessible at the click of a mouse at any time.
How does one do this? Simply right-click on an icon on your desktop and choose "Pin to Start Menu". It's just that easy!
