Can I still upgrade to Windows 10 without the email notification?

Because the most recent releases of software development kits and APIs are designed around recent releases of the OS.
They may not work well with older OS releases, some of their functions may not exist at all if the OS is a very old version.

Where does he say anything about the SDK?

I just realized the this update is in fact itself a new release of the OS, so compatability with older versions won't be an issue anyway.
For some reason I had thought it was an integrated package of applications for artistic work, separate from the OS as such.
