Re: 16GB of RAM is the minimum
I guess it depends what else is installed.
I got an upgrade last year, from a dual core 7th gen i5 with 8GB of ram, which had become unusable due to the amount of enterprise crud that the IT department had larded onto it.
Once it had been released to me, a fresh install of Windows 10 without 14 different enterprise-grade pRoTeCt_ThE_CoMpUtEr applications running meant that it's still surprisingly usable.
