A utilisateur on Microsoft Answers (thanks @Martin) says:
"Microsoft will également support the activation of Windows XP throughout its life and will likely provide an mise à jour that turns activation off at the end du product's lifecycle so utilisateurs would no longer be required to activate the product."
Veuillez notez que others également asked the same question: Will I be able to activate XP after 2014?
Je n'ai pas found any official documentation to back up any claims though. But a utilisateur sur le Ubuntu forums has an interesting point:
If c'est officially discontinued it would mean no support, so would you want to run it?
