We have just finish installing our Windows 8 recovery ISO and al upgraded to Windows 8 Pro 8.1. However restoring data such as documents, hyper-v VMs, etc. we noticed that we had Windows 10 running when the PC failed.
We know that the free upgrade to Windows 10 had a expired date; question,
Are out of the expired windows 10 update date?
With issues like the one that happens to us, where we did update to Windows 10 but our PC fail and proceeded to recover, how can we still update for free our recovered windows 8 pro version to Windows 10?
