Unlucky for some: it's 13 January 2015, and that means the end of free support for Windows 7.
Update: Speaking of end-of-support dates, there were a few reports this week about the Chinese government supposedly requesting an extension of Windows XP's planned end-of-support date of April 2014.
Microsoft's official response to this request (via a company spokesperson) is no.
If you're worried about security, Microsoft will continue to patch security issues, so if you do stick with Windows 7 your computer shouldn't suddenly become vulnerable to hackers targeting the software.
-- they're skipping 9, for some reason -- which is due in the second half of this year.
Microsoft is committed to working with end-users, businesses and governments in China to migrate their systems to a modern OS that better protects against security threats and is designed for modern work and life usage scenarios."Every Windows product has a lifecycle, which begins when it is released and ends when it is no longer supported. Customers will still be able to use Windows XP, but as a reminder, after April 8, 2014, Windows XP users will no longer receive new security updates, non-security hotfixes, free or paid assisted support options, or online technical content updates from Microsoft.
