SP1 for Windows 7 is not required for upgrading via the Media Creation Tool. It's only required if the user wishes to upgrade via Windows Update. Judging from the problems people are having, it appears as if Windows Update is the least reliable method of getting a successful upgrade. I've successfully upgraded 7 computers in my household now and done two clean installs after upgrades. Windows 10 is running perfectly on all my PCs and all have permanent activations according to slmgr /xpr results.
