Prevent set of users(admin users) to run or manage schedule task using GPO

To deny permissions for creating, managing, or deleting Task Scheduler tasks for specific administrator users, you can utilize the Group Policy Editor on Windows Server. Here's how you can achieve this: 1. Open Group Policy Management Editor: - Press Win + R, type gpedit.msc, and hit Enter. - Navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment. 2. Edit User Rights Assignments: - Look for user rights like "Create Basic Task," "Manage Scheduled Tasks," and "Delete" under User Rights Assignment. - Double-click on the specific policy you want to modify. 3. Add or Remove Users: - Click Add User or Group to deny the right, and specify the user account you want to restrict. - Click Check Names to validate through. 4. Remove Default Administrators Group: - If you want to deny the permission to a specific administrator user but not others, remove the default Administrators Group from the policy. 5. Apply Changes: - Close the editor after making the necessary adjustments, and the changes will take effect. Remember, when making changes to the Group Policy, ensure you are either logged in as a domain administrator or using an account with the necessary permissions to make these edits. Always test Group Policy changes in a controlled environment before applying them system-wide to avoid unintended consequences. Also, consider creating a System Restore Point before making major policy changes to revert in case of any issues.
