Check Windows Updates Powershell

Gets the list of available Windows updates for a single Windows machine. Can be run through any remote client or process with the ability to execute Powershell scripts. Can be run with arguments for a grace period of days to report OK and not perform the full check. Does not return drivers or toolbar updates. Some updates may show as unknown if Microsoft has not issued a severity for them.

Get list of available updates from Microsoft Update Server, no matter how recent the last check was.
