Keep in mind that if you’re running Windows 8, the software giant will let you upgrade for free starting October 18th from the Windows Store. So, who needs to buy a copy of Windows 8.1? Basically all those users currently running Windows 7 or previous version of the OS, and those who are building a custom PC. As you may notice there is no mention of an upgrade version of the software and that’s because Microsoft is discontinuing that option — only full versions from now on –. For full pricing details, read this previous article. Although, Microsoft defines Windows 8.1 as an update, this is much more than that. Installing the latest version feels like how Windows 8 should have been from day one. You’ll get a more stable operating system with hundreds of new changes such as: the return of Start button, the ability to boot straight to the desktop. You can now personalize the Start screen in a number of ways, new tile sizes, new Microsoft apps, new search experience, you can now find all the Control Panel setting in PC settings, and a lot more.
