Windows Vista has come and gone, Windows 7 is still here, but even that has been replaced with Windows 8 and now we have Windows 8.1. But, there are plenty of people still on the ageing Windows XP, and this has to stop.
Director of Trustworthy Computing at Microsoft, Tim Rains, has reminded people that the company will no longer provide support for Windows XP once it strikes midnight on April 8, 2014. This will end security updates for Windows XP, which will leave it more vulnerable to malware. The company stopped supporting Windows XP Service Pack 2, and within two years "its malware infection rate was 66 percent higher than Windows XP Service Pack 3."
We should expect similar numbers for malware in Windows XP SP3, so you might want to upgrade, especially when the malware infection rate of Windows 8.1 is around six times smaller.
