Hello Faye Marie Entienza,
The "Update Orchestrator" task in Task Scheduler is a built-in Windows task, responsible for managing Windows Update operations and related tasks. It plays a vital role in checking for, downloading, and installing Windows updates, as well as scheduling reboots when necessary to complete the update process.
You can always alter the behavior of this Task, by changing properties such as: Active Hours, or Power Options in order to limit the activity. However, since the task is Built-in it will not be possible to disable it.
Another option to prevent unexpected Windows Update reboots, is to control the behavior using Group Policy. You can check the next steps for reference:
In GPEDIT, you can access the path: Computer Configuration> Administrative Templates>Windows Components>Windows Update
There, you can change the next policies:
-No auto-restart with logged-on users for scheduled automatic updates installations: If this policy is enabled, Windows should not automatically restart the server if a user is logged in. Ensure that this policy is set to "Enabled."
-Always automatically restart at the scheduled time: If this policy is enabled, Windows will automatically restart at the specified time regardless of user activity. Ensure that this policy is set to "Disabled" or "Not Configured" to prevent automatic restarts.
-Configure Automatic Updates: This policy allows you to control when and how updates are installed. You can specify options like "4 - Auto download and schedule the install," "3 - Auto download and notify for install," etc. Review this policy to ensure it aligns with your organization's update management strategy.
