Microsoft end support for Windows XP on April 8 2014. The 13 year old operating system, a big success in its day, has reached the end of the road.
If you have any computers running this software, they will still work normally on April 9th. However, the constant upgrading and patching that goes on in the background will stop. The end of support is a green light to hackers and virus writers meaning that these computers are practically certain to come under attack and may well quickly become unusable.
This is no small problem. According to Net Applications, nearly 30% of the world was still using XP at the end of December 2013.
Sadly, there is no option but to upgrade or replace the XP computer, even if it remains perfectly serviceable.
