Microsoft ended technical support, including automatic security updates, for Windows XP on April 8, saying it wants to use its resources for supporting newer technologies.
However, last week a security flaw was discovered in Internet Explorer, versions 9 through 11, which enabled hackers to gain access to computers using Windows XP.
The new security patch will be installed automatically on most computers using Windows XP. Users who opted to use the manual update are being encouraged to do it as soon as possible.
Microsoft is calling on users of Windows XP to upgrade their operating system and install the latest version of Internet Explorer 11.
