The info I've found on this subject is somewhat confusing, so wondering if anyone here could shed a light on the issue of how many real/logical cores are supported by Windows 10 Pro and Windows 10 Enterprise. (I have a spare license for each.)

A friend is upgrading his office server early(ish) next year, and I'll be getting his existing 18 month old or so mobo, 64 gig of RAM and 8-core/16 logical Threadripper CPU for free, which I hope to build up into a new system over time. Would either or both Windows versions support this 'out of the box' or would I need to get another license from MS?

Just heard from a friend, up to 64 should be fine. :) Just like most Gnu/Linux distros and *BSD ones then. Time was you had to get a separate edition of NT for anything more than 4 CPUs.... (Though I think that really meant the then Alpha and MIPS versions - don't think I can recall any Intel or PPC based systems with more than 4 at that time, with the exception of IBM's POWER based systems like the RS/6000 series.)

It depends on the windows variant and architecture. Win10 Pro x64 supports 2 sockets, 256 logical cores, and up to 512GB of RAM.
For more sockets, you need to get a server OS.

Some people think that not all cores work in a multicore computer, in fact, this is not the case, they all work and always, but at different frequencies. The fact is that with a large number of cores, only work is optimized, that is, data is processed faster. One more point. If the program is not optimized for several cores, then, no matter how many there are in the computer, the program will still use only a certain number. The kernels on all modern computers always work without restrictions. Why should developers limit CPU and memory usage, especially when Windows starts.
Note that if the checkboxes are in the MSConfig utility, it means that there are no restrictions. But you can do it yourself, as this utility is for testing software.
