Windows 8 Service Pack 1 8.1 will be made available starting some time in October 2013, according to various sources.

Included in the free update will be several tutorials on the new user interface. The exclusion of such tutorials in Windows 8 was a strange decision by Microsoft, since they were in every previous version of Windows.

The update will also include a variety of changes related to user interaction, affecting the use of touch, mouse and keyboard input. Context menus will be improved for better usability.
