You got some bad info. XP will still be receiving security updates for another 5-6 years. Possibly longer, depending on how many large customers are still using XP around the time XP is slated to go end of life.
Once it does reach end of life status, there will be NO further updates. Third party updates are not going to be available, because they would require access to the Windows source code, and Microsoft does not give that out.
I WAS TOLD IN 09 no more windows updates for xp does anybody know of third party sites that will have updates? please post links thanks
