Let’s be honest: Windows 8 has been fraught with problems. Completely overhauling a well-known desktop interface versatile enough for mobile has left Microsoft attempting to shoehorn Windows 8 into both desktops and tablets — users are left with a steep learning curve. Windows 8.1 is now here (and free for Windows 8 users), and promises to be easier. Along with little performance changes, Windows 8.1 features an updated search system, a greater focus on Sky Drive, Internet Explorer 11 and the return of the familiar Start button. Download the system — along with updated apps — on Microsoft’s website.
