Is it possible to upgrade Windows 8.1 -> Windows 10 -> Windows 8.1 -> Windows 10 for free?

I used Windows 8.1 and upgraded to Windows 10 for free.

As I wrote it, there are many programs that can't be used in Windows 10, so I'm going to downgrade it again and write it in Windows 8.1.

But later on, programs will be well supported on Windows 10.

Then it will be time to upload to Windows 10.

Will it still be possible to upgrade to Windows 10 for free?
