If you are running Windows 8.1, one of the anticipated improvements is the ability to boot directly to the Windows desktop instead of the Start screen. Here is how you do it.
Right click the Windows Taskbar and click Properties.
Go to the Navigation tab, under the Start Screen heading, check off the options
- Go to the desktop instead of the Start when I sign in.
Click Apply and OK
In future you will automatically be taken to your desktop.
