Windows 7 vNext
Windows 7 is in extended support until 2020.
If extended support ends, it is likely removed from SCCMs supported OSes.
In certain cases you have to keep Windows 7 "alive", e.g. factory, where the cost of the machine that the PC is controlling is far higher, then in an office environment.
To keep this systems alive we can´t deploy a cloud solution.
Deploying the cloud will have the risk we can´t control the Windows 7 machines anymore and can´t setup a new machine anymore, in case the old one needs to be replaced or reimaged.
So keeping at least a minimum support for old OSes like Windows 7 in 2020 for at least a few more years, would help here to build trust in the cloud and consume cloud services.
We would at least need 5 additional years, like the 5 years that we would "buy" with deployment of SCCM 2016 (the on-Prem) right now - it is supported for 10 years from now!
