So your saying you ran the script and your key is not one of the generic activation keys? If so then you have your own personal key you should save it and write it down if this is the caseProduKey shows generic key i.e 1 of the 4 generic keys mentioned here on MT.
Windows 10 Home - YTMG3-N6DKC-DKB77-7M9GH-8HVX7
Windows 10 Home SL- BT79Q-G7N6G-PGBYW-4YWX6-6F4BT
Windows 10 Pro - VK7JG-NPHTM-C97JM-9MPGT-3V66T
Windows 10 Pro VL-MAK - QJNXR-7D97Q-K7WH4-RYWQ8-6MT6Y
The script shows a new key i.e not 1 of the above 4 keys.
