Windows 10 Activation failed
I have an Inspiron 3542 laptop that I just upgraded to Windows 10. The update completed but now the device is saying Windows 10 needs to be activated. The error message reads: "Activation failed because this device doesn't have a valid digital entitlement or product key. Error code: 0x803f7001". This is a Windows 7 Pro device purchased from Dell in 2014. I tried calling the help line but they bumped me over to a fee for service help line because I am out of warranty. If they sold me a device with an invalid key shouldn't that be on them to correct regardless?
Is there a simple fix to this. It was activated and running fine before this upgrade attempt. Should I just revert it to 7 Pro and leave it alone?

Al Owther,
Below is information to hopefully get your Windows 10 activated.
How to troubleshoot Product Activation in Windows 10:
This Activation Error Code 0x803F7001 in windows 10 is caused if you Clean install Windows 10 using flash drive. This Error may also occur if you update your BIOS.
Follow the Cycle Again:

Thank you. I will try this. I did an upgrade from a disk created through the media creation tool and I did it straight from the desktop. I had heard that there were issues doing it as a clean install and did not want to deal with those issues.
