Task Manager displays incorrect processor affinity in Windows Server 2022

This article describes a known issue in which Task Manager displays incorrect processor affinity in Windows Server 2022.

When you use Task Manager to set process affinity in Windows Server 2022, the processors might show processor groups incorrectly.

For example, when you right-click a process under the Details tab in Task Manager and select Set affinity, a system with 64 logical processors and two NUMA nodes incorrectly shows four sets of CPU nodes numbered repeatedly as follows:

CPU 0 (Node 0)
CPU 1 (Node 0)
...
CPU 15 (Node 0) 
CPU 0 (Node 1)
CPU 1 (Node 1)
...
CPU 15 (Node 1) 
CPU 0 (Node 0)
CPU 1 (Node 0)
...
CPU 15 (Node 0) 
CPU 0 (Node 1)
CPU 1 (Node 1)
...
CPU 15 (Node 1) 

This is a known issue in Windows Server 2022, and it doesn't affect the performance or usage of the system.
