In an interview with Polygon, Microsoft engineer Dan Kuchera said that he had seen people with older versions of Windows 10 running the beta program with Windows 10.
“I think the most common mistake I see is people not knowing that Windows 10 will run on older versions, and Windows 7 and 8 users don’t know that Windows 7 or 8 will not run on Windows 10,” Kuchersaid.
“So if you see a user on Windows 7 with a Windows 10 build number of 64, the user is running an older version of Windows.”
He went on to say that it’s not just users that are affected by this issue.
“The biggest issue is people who are running Windows 10 for the first time, which I’m sure will be a problem for a lot of people.
People are going to start using the Anniversary Update to upgrade to Windows 10, which will take time and it’s going to be a little bit of a pain,” Kuchhera explained.
“But the main reason people are running it at all is because they want to, because it’s so new, and they want Windows 10 to be the best operating system.
But there’s a lot more that goes into upgrading to Windows, and we don’t have an exhaustive list of the issues and the things that are going wrong that might be causing this.”
Windows 10 Pro, which is an upgrade to the Windows 10 Professional edition of Windows, will be supported until July 21st.
However, the Anniversary Edition of Windows will be available for a limited time.
This means that Microsoft may not be able to offer Windows 10 64-bit for free to all users for at least two more weeks, as per the terms of service for the Anniversary edition.
