You can drop something that doesn't exist but was announced. Thechnically Skylake support for Win7 wasn't announced, but the effect is the same since there was an implicit expectation that the feature would come.

From where did this implicit expectation come from?
Windows 7 mainstream support ended in Jan 2015 and that was known since forever.
Extended support implies:
>Microsoft no longer supplies non-security hotfixes unless you have an extended support agreement
>All warranty claims end
>Microsoft no long accepts requests for new features and design changes
But I presume dropping support just means not being able to use the latest features.
Even a very old system image of windows 7 will run on the very latest skylake. It doesn't need the very latest updates. I doubt they will create a kill switch in a windows update that refuses to boot if the system detects a too modern CPU.
