Microsoft this week introduced the eagerly-anticipated Windows 8.1 August Update, a pack of improvements that actually brought fewer new options than expected, but lots of bug fixes for the core operating system.

As we’ve already told you in a few days ago, Microsoft published a list of the new features included in the August Update on the official KB2975719 bulletin page, but the company updated this link yesterday to also reveal the bugs addressed by this new OS update.

As reported by Manish Singh of WinBeta, this list contains a number of improvements for Windows 8.1 and RT 8.1 applications, including OneDrive and Xbox Music, but also several new options for both the Modern UI and the desktop.

Windows 8.1 August Update is delivered as an optional update, but you still need the Windows 8.1 Update released in April in order to deploy it. Microsoft focused especially on performance and reliability in this new update, so no new features and major changes are included. Instead, users of both desktops and tablets are recommended to deploy it in order to make sure that everything works as expected.

You can find the complete list of bug fixes in the list after the jump, while the new options integrated into Windows 8.1 are available here.
