 For instance, an assessment call attempts to fetch the latest patch that's available from the image's OS family to check support. It stores this support-related data in an Azure Resource Graph table, which you can query to see the support status for your Azure Compute Gallery image.
 
-## Check the preview
-
-Start the asynchronous support check by using either one of the following APIs:
-
-- API Action Invocation:
-  1. [Assess patches](/rest/api/compute/virtual-machines/assess-patches?tabs=HTTP).
-  1. [Install patches](/rest/api/compute/virtual-machines/install-patches?tabs=HTTP).
-
-- Portal operations. Try the preview:
-  1. [On-demand check for updates](view-updates.md)
-  1. [One-time update](deploy-updates.md)
-
-Validate the VM support state for Azure Resource Graph:
-
-- Table:
-
-  `patchassessmentresources`
-- Resource:
-
-  `Microsoft.compute/virtualmachines/patchassessmentresults/configurationStatus.vmGuestPatchReadiness.detectedVMGuestPatchSupportState. [Possible values: Unknown, Supported, Unsupported, UnableToDetermine]`

-We recommend that you run the Assess Patches API after the VM is provisioned and the prerequisites are set for public preview. This action validates the support state of the VM. If the VM is supported, you can run the Install Patches API to begin the patching.
