No, there are no built-in check for Windows updates in agent. We was thinking about adding this, but it's quite complicated to check this from C, so we postpone it. Best solution is probably to creae some vps or power shell script and add it as external parameter to agent.
Btw, you can check that firewall, antivirus, and anti-spyware is active and up to date using the following parameters (provided by WMI subagent):

System.AntiSpywareProduct.Active
System.AntiSpywareProduct.DisplayName
System.AntiSpywareProduct.UpToDate
System.AntiVirusProduct.Active
System.AntiVirusProduct.DisplayName
System.AntiVirusProduct.UpToDate
System.FirewallProduct.Active
System.FirewallProduct.DisplayName
System.FirewallProduct.UpToDate
