SAN FRANCISCO – 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.
Meanwhile, sales of smartphones and tablet computers are booming. The biggest beneficiaries have been Apple Inc., the maker of the iPhone and iPad, and Samsung Electronics Co., which sells the most devices running on Google Inc.’s Android software.
Google is also benefiting from Android’s popularity through increased traffic to its services, creating more opportunities for the company to display ads.
By contrast, leading PC makers such as Hewlett-Packard Co. and Dell Inc., which primarily sell Windows-powered machines, have been mired in a financial funk that has battered their stocks and raised questions about their futures.
Despite the troubling signs, Microsoft insists it’s pleased with Windows 8’s performance.
The company, which is based in Redmond, Wash., says more than 100 million Windows 8 licenses have been sold so far, up from about 60 million licenses in January. The licensing volume “is in the same general ballpark” as Microsoft’s previous operating system — Windows 7 — at a similar juncture of its sales cycle, said Tami Reller, the marketing and financial chief for Microsoft’s Windows business.
Reller said Microsoft still realized that changes are needed to make Windows 8 easier to navigate and capable of taking full advantage of technology improvements that have come out since October.
For now, Microsoft isn’t saying what kind of changes will be introduced with the release of Blue in time for the holiday season.
“I view this as a relaunch of Windows 8, finally giving everyone a fully baked version,” said technology analyst Patrick Moorhead.
