SAN FRANCISCO (AP) — Microsoft is trying to fix what it got wrong with its radical makeover of Windows. It’s making the operating system easier to navigate and enabling users to set up the software so it starts in a more familiar format designed for personal computers.

The revisions to Windows 8 will be released later this year. The free update, called Windows 8.1, represents Microsoft’s concessions to long-time customers taken aback by the dramatic changes to an operating system that had become a staple in households and offices around the world during the past 20 years. Research group IDC has blamed Windows 8 for accelerating a decline in PC sales.
