Update: Apparently, the support agent provided incorrect information. Technology journalist, Ed Bott, ZDNET, confirmed with Microsoft, the free upgrade offer has indeed ended.
Procrastinators can breath a sigh of relief. A reply from a community forum participant, Martmcd, confirmed in a chat session with a Microsoft Answer Desk agent; the Windows 10 Free Upgrade Offer has been extended for 2 more weeks. The free upgrade launched on July 29, 2015, provides a full version Windows 10 upgrade for PC and devices running a qualifying, genuine, activated Windows 7 or Windows 8 license. The free upgrade was scheduled to last for one year. This week many users started scrambling at the last minute to grab the upgrade. Users who started the upgrade began hitting a widespread 99% hang using the Windows 10 Upgrade Assistant. Microsoft Forum Moderators reassured users who started the upgrade before the deadline, could contact chat support to get a reprieve.
Todays news gives users a little more breathing room to sort out whatever problems might be preventing successful upgrades. This should also give many users the chance to skip Windows 10 November Update and head straight to the Windows 10 Anniversary Update set for August 2.
