To address criticisms from both consumers and businesses, Microsoft has made a notable number of changes in the free Windows 8.1 update.

To address another common complaint about Windows 8, Microsoft has built greater flexibility into displaying Modern UI apps (downloaded from the Windows Store). The previous implementation limited Modern app instances to just two instances running side-by-side, with one app running in a large window and the second app in a tiny window. With Windows 8.1, it is now possible to make the second app window take up either a third, half, or two-thirds of the screen. In addition, the operating system will allow PCs with larger screens to support up to five apps windows side by side, though this will only be possible if your monitor has sufficient pixels, of course.
