WinBeta posted a story that Microsoft may be working on an option to jump straight to the desktop for users in Windows 8.1

For those upgrading to Windows Blue, you might now have the option to remove the Start Screen. According to the report, after examining the code in twinui.dll, there is a line that is "responsible for disabling the Start Screen" and after disabling or modifying the code it makes the system "go to the desktop automatically." Those using Windows 8 or the leaked Windows 8.1 build, you will obviously know by now that this option isn't yet available.

  Microsoft to allow users to jump straight to desktop in Windows 8.1?
