+### Cause
+
+The prerequisite for scheduled patching and attaching schedules isn't being set correctly when utilizing the **Schedule recurring updates using Azure Update Manager** and **Set prerequisite for Scheduling recurring updates on Azure virtual machines** policies during create for specialized, generalized, migrated, and restored VMs because of the way the current *Deploy If Not Exists policy* is designed. Post-creation, the policy will show these resources as non-compliant on the compliance dashboard.

 ### Issue
-There are remediation failures for VMs which have a reference to the gallery image in the Virtual Machine mode. This is because it requires the read permission to the gallery image and it is currently not part of the Virtual Machine Contributor role.

 ### Resolution
 -	For all the new assignments, a recent change is introduced to provide **Contributor** role to the managed identity created during policy assignment for remediation.  Going forward, this will be assigned for any new assignments.
--	For any previous assignments if you are experiencing failure of remediation tasks, we recommend that you manually assign the contributor role to the managed identity by following the steps listed under [Grant permissions to the managed identity through defined roles](../governance/policy/how-to/remediate-resources.md)
