This is an interesting thread. I don't have a solution, other than a phone activation as simrick suggested.
Double check your ISO / install media to make sure it matches your installed system (Home).
Command Prompt (Admin)
DISM /Get-WimInfo /WimFile:F:\sources\install.wim /index:1
DISM /Get-WimInfo /WimFile:F:\sources\install.wim /index:2
-- OR --
DISM /Get-WimInfo /WimFile:F:\sources\install.esd /index:1
DISM /Get-WimInfo /WimFile:F:\sources\install.esd /index:2
F: is only an example - change the drive letter to match your install media or mounted ISO
