Windows XP's huge drop last month made shambles of earlier estimates that forecast it would still account for more than a third of the world's personal computer operating systems at the end of April 2014. After the large decline of last month, revised projections now peg XP's expected April 2014 user share at a lower range, between 23% and 28%, based on the latest three-month and 12-month averages, respectively.
Overall, Windows slipped by four-tenths of a percentage point to 91.2%. Linux, which gained three-tenths of a point to end August with 1.5%, and Apple's OS X, which grew by a tenth of a point to 7.3%, took up the slack.
Within the Windows universe, however, there was plenty of movement, as XP's decline best illustrated.
Windows 7, which has assumed the mantle as the standard in business, boosted its user share by over a percentage point, climbing to 50% of all machines running a Microsoft operating system. Windows Vista continued to lose users, falling to 4.5%.
Most of the share lost by XP, however, ended up in Windows 8's camp: The newest OS grew by a record 2.5 percentage points to close August with 8.4% of all Windows-powered systems.
Windows XP's last public security update is planned for April 8, 2014.
