Re: I have a Fujitsu Celsius R650 workstation

The real question is: will it continue to "run fine" after an update to some future version of "normal Win 10 Pro" ?
The Workstation edition will support up to 4 CPUs and lots of cores, but it will cost much more than a 'normal' edition.
It seems most likely that the changes in licensing are related primarily to sales of new machines and will be restrictive on OEMs. Computers with up to 4 core (probably on 1 CPU) can have 'normal' Win 10 Home or Pro installed, but if it has more than 4 cores, or more than 1 CPU, then it _must_ be sold with Workstation edition. This will increase revenue to Microsoft, which is always the aim of _any_ changes.
A clean install of a retail version may also limit the cores in use to 4 unless the Workstation edition is paid for.
Whether this can be applied to existing machines is a separate issue. It seems unlikely that an update would cripple a computer by only running on 4 of the cores, or stop altogether, until an additional licence is purchased, but it may nag you saying that your machine would be better by sending more money to MS. Also, if (or when) you have to start paying a monthly subscription then this may be based on the number of cores that the computer has, regardless of whether it is Pro or Workstation.
