A few weeks before the official release of Windows 8, Microsoft has released an update for the operating system that delivers improvements in "performance, power management and battery efficiency, media playback, and compatibility."
Through Windows Update, users who are utilizing early versions of the OS will receive a prompt for the update. Microsoft said it'll offer increased power efficiency in order to extend battery life, Windows 8 apps and Start screen performance improvements, improved audio and video playback, as well as improved application and driver compatibility with the forthcoming operating system.
Windows chief Steven Sinofsky said the changes are usually included within an operating system's initial service pack, "[but] during the final months of Windows 8 we challenged ourselves to create the tools and processes to be able to deliver these 'post-RTM' updates sooner than a service pack."
Microsoft has already updated a series of Windows 8 applications. The operating system itself launches on October 26.
