+# 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:
+
+```output
+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.
