Windows 8.1 is finally here, and it’s a significant update. Sure, the Start menu isn’t coming back, but you do get a more customisable Start screen, much improved apps (and more options for running them side by side), enhanced Search with Bing integration, smart syncing with SkyDrive, Internet Explorer, and a host of new tweaks and customisations (including the ability to boot straight to the desktop).
Should you upgrade from Windows 8.0? Probably, although you’ll need to make sure that your most important applications are Windows 8.1-compatible. This isn’t likely to be a big issue – low-level programs like antivirus tools are the most likely to be affected, and they’ve mostly been 8.1-ready for months – but it’s still wise to check your main applications for updates, first.
