Windows – How long will Microsoft support Windows XP Professional

A user on Microsoft Answers (thanks @Martin) says:

"Microsoft will also support the activation of Windows XP throughout its life and will likely provide an update that turns activation off at the end of the product's lifecycle so users would no longer be required to activate the product."

Please note that others also asked the same question: Will I be able to activate XP after 2014?

I haven't found any official documentation to back up any claims though. But a user on the Ubuntu forums has an interesting point:

If it's officially discontinued it would mean no support, so would you want to run it?

I see no mention of 32bit or 64bit. This leads me to wonder if this may actually be your problem. In the end, the best solution is to ask Acronis. You paid for it so just ask. Worst thing they can do is refuse to help you.
