First: Given the very large installed base of Windows 7 & 8, 14 million upgrades is OK.
Second: The upgrade is Free to the Win 7 & 8 base, so again OK.
Given the long free beta of Win10, I hope for MS’ sake that this upgrade goes smoothly. I LOVE COMPETITION and watching an upgrade war between Apple & MS brings joy to my heart!
I have an older Dell running Windows 7 that appears to be haunted. I’m hoping Windows 10 will exorcise its demons; otherwise it’s going to the recycle bin.
