XP is not "ending" and will go on working fine after April 2014.
All that is happening is that Microsoft are ending official support.
But thousands of companies are still using XP so I am sure Microsoft will still supply fixes for important problems.
p.s. Having said that if you are still running a computer with XP it may be time to buy a new one.
You will be amazed a zippy a new computer will be, but go for Windows 7 don't go for Windows 8.
After all, you don't still drive a Ford Anglia do you?
