The SkyDrive app doubles as File Explorer
The SkyDrive app isn't just for cloud-based files. The navigation control at the top of the window also includes the option to browse and manage local files as well as those stored on a network. In essence, the SkyDrive app is a stealthy, touch-friendly replacement for File Explorer on tablets.
Old and new Control Panel
One of the most common complaints about Windows 8, especially on tablets, is the way it forced you to switch to the desktop for many common configuration tasks. In Windows 8.1, the touch-friendly PC Settings selection is greatly expanded. For most of the tasks you're likely to tackly, you can take your choice of the desktop Control Panel or the new-style alternative. This example shows these alternate views of Display settings.
No more five-device limit for apps
You'd be amazed how quickly you can run into the five-device limit that applies to Windows Store apps. In Windows 8, the only fix was to remove one of your five authorized PCs from the list. Windows 8.1 eliminates this frustration by upping the limit for app installations to 81 devices.
(Prediction: at least three people will hit this limit and tell the world about it in the Talkback section of this gallery.)
