Microsoft is offering Windows 8.1 users an extra month to keep receiving security updates, with the Update Requirement having been moved from May 12 to June 10. Both days are a week before Patch Tuesday of either month. Microsoft noted that a number of users have not manually upgraded to Windows 8.1 yet, and that only those with Automatic Update enabled had received the update in the first place. "We're confident that within the next month, the majority of the remaining customers who haven't updated their devices to the Windows 8.1 Update will be able to do so," said the company in a statement.
This follows a period of steady growth for Windows 8.1. The OS finally achieved 5 percent market share by late April. Windows 8, its direct predecessor, lost share after some decline in March - this is mostly down to Microsoft simplifying the Windows 8.1 upgrade procedure to just one download. In the meantime, reigning champion Windows XP continues to hang on to 26.29 percent of its market share, in spite of losing its security updates. It is second only to Windows 7, at 49.27 percent.
