I don't have any plans to upgrade any current device either. Why mess with a machine that is working perfectly now? The upgrade offer begins on 7/29/15 and will be available for one year until 7/29/16. If a person accepts the free offer, it is free forever on that device. The person would not be required to pay for it after that time. http://www.microsoft.com/en-us/windows/windows-10-faq?ocid=win10_auxapp_context What are the basic facts of the Windows 10 upgrade?Microsoft is making Windows 10 available as free upgrade for qualified Windows 7, Windows 8.1, and Windows Phone 8.1 devices.
