Welcome, Leslie. I am Cory.
I am sorry to say but the free upgrade period has ended for regular users. While it seems like a good idea to upgrade, it has turned out to be a problem for many users. Many have wanted to go back to Windows 8 or 8.1.
However, with that in mind, it is up to you what you would like to do.
You can purchase is for $119 for the home edition or $199 for the pro edition.
If you use assistive technologies, then you are still eligible for a free upgrade. You can find more information about it here. - https://www.microsoft.com/en-us/accessibility/windows10upgrade?tduid=(14c348e893a91089cb2980533c6ee123)(256380)(2459594)(TnL5HPStwNw-0FBZfNm6YPFXNhiu3o52rA)()
I hope I have answered your question today.
