Actually XP's end of life is today.
A note to the lurkers that are still running XP:
If you absolutely must continue using XP, then immediately stop using the Internet Explorer (IE) web browser that comes with XP. Install either the Firefox or Chrome web browser and start using one of those instead. Both Firefox and Chrome are free for the downloading.
Internet Explorer will no longer get malware prevention patches, so you are really hanging your you-know-what in the wind using it. Not only that, but using IE identifies you as an XP user to every web site (good or bad) that you visit, effectively painting a big red target on your back as you surf the 'net.
Alternate browsers will continue getting patched as new malware threats arise.
Next, make sure you have a good anti-virus program installed - every bad guy on the planet is going to be gunning for you and your XP box. That said, even an anti-virus program will not protect you like a fully-supported operating system would.
BTW, most of the free anti-virus programs are not very good - you get what you pay for.
Now it is time for this physician "to go heal himself". My wife is still running XP, so it is time for a new motherboard and Win7-Pro64 for her.
