We may refer to the following steps to know the "Start to End process" of the policy for the "Feature update to Windows 10" and its deployment in client logs.
After the deployment and the deployment policy have been created on the server, clients receive the policy on the next policy evaluation cycle.
Firstly, we add the "Deployment Unique ID" column in the console to find the "Deployment Unique ID" of the deployment. For the deployment in the following example, the deployment unique ID is {4B54EF72-EA95-4031-8CCD-02F22B1C625D}.
Step 1: Policy Agent receives the policy on manual policy retrieval or on schedule. When policy is received, According to the "deployment unique ID" on the console, the following entries can be found in PolicyAgent.log(Records requests for policies made by using the Data Transfer Service.):
There are also records in PolicyEvaluator.log (Records details about the evaluation of policies on client computers, including policies from software updates.):
Step 2: After the policy is evaluated, the scheduler for the deadline is evaluated. This is done by the Scheduler component. Scheduler notifies the Updates Deployment Agent to initiate the deployment evaluation process, as shown in Scheduler.log (Records activities of scheduled tasks for all client operations.):
Step 3: Updates Deployment Agent starts the deployment evaluation process by requesting a software update scan to make sure that the deployed updates are still applicable. In UpdatesDeployment.log (Records details about deployments on the client, including software update activation, evaluation, and enforcement.):
Step 4: At this point, the scan request is handled by Scan Agent component. Scan Agent calls WUAHandler to perform a scan and then hands the results back to Updates Handler and Updates Deployment Agent. After the scan is completed, Updates Deployment Agent is notified. This is noted in UpdatesDeployment.log as follows:
