+## Understanding update states
+
+Updates can go though many phases from when they're initially deployed to being installed on the device. Transition from one state to another can be rapid, which makes some states less likely to be displayed in reports. The workbook can report the following high-level states for a device update: <!--8052067-->
+
+- **Offering**: The update is being offered to the device for installation
+- **Installing**: The update is in the process of being installed on the device
+- **Installed**: The update has been installed on the device
+- **Cancelled**: The update was cancelled from the [deployment service](deployment-service-overview.md) before it was installed
+- **Uninstalled**: The update was uninstalled from the device by either an admin or a user
+- **OnHold**: The update was put on hold from the [deployment service](deployment-service-overview.md) before it was installed
+- **Unknown**: This state occurs when there's a record for the device in the [UCClient](wufb-reports-schema-ucclient.md) table, but there isn't a record for the specific update for the specific device in the [UCClientUpdateStatus](wufb-reports-schema-ucclientupdatestatus.md) table. This means that there is no record of the update for the device in question.
