System only using 4 of 6 cores. AMD
I have an AMD Ryzen 3600 6 cores.
Windows only sees 4 of those cores. I ran both Everest as well as CPU-Z and both show 6 cores but only 4 functional.
How do I enable the missing two cores?

[SOLVED]
I experimented and seem to have found a working solution for my system.
First part had me worried!
1. msconfig / boot / advanced was set to maximum 8 processors. I only have 6 but confused because I have only one processor with 6 cores. ( Thank you Microsoft for confusing info ) I set to one processor and rebooted and found only one processor and one core working. ( ouch )
I could not set msconfig back so unchecked number of processors, crossed fingers and rebooted.
2. Upon reboot the missing cores appeared!
I left msconfig with number of processors unchecked.
So it would appear that trying to select the number of processors there is what causes the problem. Just uncheck that and reboot.
