DAP tracks visits to more than 4,000 websites on over 400 different domains maintained by U.S. government agencies, so its data is highly U.S.-centric.
Most other editions of Windows stuck to long-established trends: Windows XP's global share of all Windows PCs slipped slightly to 12%, and Windows 7's user share dropped to 54% of all Windows machines. But the combined share of Windows 8 and 8.1 climbed to 15% in April, an unusual uptick that may be less a signal of a renaissance of those 2012-2013 operating systems and more an aberration in Net Applications' data tracking.
Meanwhile, Net Applications claimed that Apple's OS X -- perhaps soon to be rebranded MacOS -- jumped to 9.6% of all personal computers worldwide, an unprecedented increase, while Windows fell under 90% for the first time to land at 88.8%.
Both those numbers were questionable simply because they pointed to extraordinary one-month changes. The previous record for a one-month increase in OS X, for example, was just one-third the size that Net Applications asserted for April.
