One of the limitations in Winos 8 was that we could not set our desired wallpaper/background to the new start screen. Instead we had to select with some images/designs Microsoft has provided by default.
With the release of Windows 8.1, Microsoft has included an option where we can have our desktop wallpaper as the start screen background. To enable this option there are 2 methods
Method 1
1) Right click on the task bar and select properties
2) In the properties Taskbar and Navigation properties window, click the navigation tab and check the “Show my desktop background on Start” option and click OK
Method 2
1) On the start screen charms bar, select the settings charm
2) Click Personalize
3) Select the wallpaper
One of the complaints with Windows 8 was that when the computer boots up/starts up it goes to the new Windows Start screen instead of the traditional Windows desktop. The new start screen is a bit of a complicated area for someone who is not IT Savvy or new to computers.
There were many 3rd part utilities which were made available to tweak Windows (modify some registry keys) in order to make Windows 8 boot directly to the desktop.
With Windows 8.1 Microsoft took the valuable feedbacks from its customers and reintroduced the start button as well as gave the option to boot directly to Windows desktop instead of the new start screen. To do this,
1) Right Click the taskbar and select properties
2) The properties Window, click Navigation
3) Select the highlighted option (checkbox) and click OK. you are done
