ensuite j'ai eu une erreur :
j'ai modifié le registre :

Tried using the default upgrade key and that wouldn't work either, ended up using steps below:

1. Open Regedit
2. Browse to key HKEY_Local Machine > Software > Microsoft > Windows NT > CurrentVersion
3. Change EditionID to "Windows 10 Professional" (double click EditionID, change value, click OK).
4. Change ProductName to Windows 10 Professional.
5. Browse to key HKEY_Local Machine > Software > Wow6432Node > Microsoft > Windows NT > CurrentVersion, change the same two values as in steps 3 and 4 above
6. Close the Registry Editor
7. Go to windows update and set key to VK7JG-NPHTM-C97JM-9MPGT-3V66T
8. Now it will runthrough the upgrade and add features during reboot.
9. Insert your Win10Pro key once the machine has restarted and Bob's your uncle...

Puis
j'ai débranché le câble réseau pour éviter la nouvelle erreur :

(peut être il fallait juste débrancher le cable réseau pour passer en pro et mettre la clé pro)
