Hello!

I need some help with activating Windows 10. I originally upgraded from Windows 7 to Windows 10 during the free upgrade period, and everything was activated correctly.

I recently reinstalled Windows on a new hard drive and also changed my motherboard. Since the hardware changed, Windows is no longer activating automatically, even though I have a valid product key. Could you please help me reactivate my Windows 10 installation?

Thank you!

    To reactivate your Windows 10 installation after changing your hardware, you can follow these steps:

    1. Use Your Product Key: Since you have a valid product key, you can attempt to activate your Windows 10 by going to Settings > Update & Security > Activation. Here, you can enter your product key and see if it activates.
    2. Troubleshoot Activation: If entering the product key does not work, you can use the Activation Troubleshooter. Go to Settings > Update & Security > Activation, and if you see a message that your Windows is not activated, there should be an option to troubleshoot. This tool can help resolve common activation issues.
    3. Contact Microsoft Support: If the above steps do not work, you may need to contact Microsoft Support for assistance. They can help you with reactivating your Windows, especially since you've changed hardware.

    Keep in mind that if you upgraded from Windows 7 to Windows 10 during the free upgrade period, your digital license is tied to your Microsoft account. Make sure you are logged into the same account you used during the upgrade.

    Καλησπέρα και πάλι,

    Μπορώ να μιλήσω με την τεχνική υποστήριξη της Microsoft του Ελληνικού τμήματος, για να διορθωθεί το παραπάνω πρόβλημα.

    If your Windows licence is based on a free upgrade from a previous Windows 7 licence that is causing the activation problem, Microsoft changed the licencing rules over a year ago, and since they changed the rules, it is no longer possible to activate Windows 10 or 11 on a new motherboard or PC with a Windows 7 or 8 based licence.

    .....................

    Εάν η άδεια χρήσης των Windows σας βασίζεται σε μια δωρεάν αναβάθμιση από μια προηγούμενη άδεια χρήσης των Windows 7 που προκαλεί το πρόβλημα ενεργοποίησης, η Microsoft άλλαξε τους κανόνες αδειοδότησης πριν από ένα χρόνο και, επειδή άλλαξε τους κανόνες, δεν είναι πλέον δυνατή η ενεργοποίηση των Windows 10 ή 11 σε μια νέα μητρική πλακέτα ή υπολογιστή με άδεια χρήσης που βασίζεται στα Windows 7 ή 8.
