Microsoft has maintained that it will discontinue support for its once dominant Windows XP on April 8, 2014. After April 8, Microsoft will no-longer offer Windows XP patches for vulnerabilities on XP. However, Microsoft will be providing updates to Windows XP’s anti-malware signatures and engine till July 14, 2015.
The continued update of the anti-malware signatures for more than one year after support ends is aimed at providing a smooth transition to newer operating systems for users and should not be seen as a reason to delay update to a supported Windows version.
According for Microsoft “Running a well-protected solution starts with using modern software and hardware designed to help protect against today’s threat landscape.”
So, if you are still using Microsoft XP, it will be a good idea to upgrade to Windows 7 or Windows 8 before April 8, 2014. If you can’t make it before then at least Microsoft still has some of your security covered till July 14, 2015.
