Microsoft is retooling the latest version of its Windows operating system to address complaints and confusion that have been blamed for deepening a slump in personal computer sales.
The tune up announced Tuesday won’t be released to consumers and businesses until later this year. The changes, part of a software package given the codename “Blue,” are a tacit acknowledgment of the shortcomings in Windows 8, a radical overhaul of Microsoft Corp.’s ubiquitous operating system.
With the makeover it released last October, Microsoft hoped to play a more prominent role in the growing mobile device market while still maintaining its dominance in PCs. But Windows 8’s design, which emphasizes interactive tiles and touch controls, seems to have befuddled as many people as it has impressed. One leading research firm, International Data Corp., says Windows 8 contributed to a 14 percent decline in worldwide PC sales during the first three months of the year — the biggest year-over-year drop ever.
