Bitcoin QT unconfirmed
After downloading and installing, when you open it for this first time, it will begin to download "blocks" you will see the process of the download as a green bar in the windows center bottom. This will take some time, depending on how fast they transfer the block to you, and how fast your internet speed is. Some say it took them an entire day, personally it took my 8~ hours of sleep and then it was done, while running on a download/upload speed of 50Mb/10Mb.
The first frame you'll see is the overview window.
