+# Understanding properties that are updated at a slower cadence
+
+There are specific fields, when using Azure Resource Graph, that are updated at a slower cadence. These fields will converge to true values over time, provided there are no updates in between. 
+
+## List of fields affected
+
+**Virtual Machines: VMs are updated asynchronously, which means that the current state does not match the "goal state" (desired state set by customers). However, these VM fields will converge over time.**
