Hi. I am running an Acer Aspire with Win8 already loaded when I bought it. What worries me is that I can't find the full Windows product key anywhere. Control panel > System gives me a Product ID (whatever that is) with four groups of 5 chars each. And if from there I click "View details in Windows Activation" I see a short "product key" (whatever that is) with half of it asterisked out (*****-PPKVT), which obviously is not the same key. I remember Windows product keys as five groups of five characters each. I'm worried in case one day I need to contact MS support and can't quote a product key. Also because I'm having a problem with Outlook 2007 (yes, I know, but I can't afford an upgrade and I'm quite happy with the 2007 version) and might need to do a Reset or Refresh of Win 8 to resolve it, and assume I might need the product key at that time.
