Description

Skype has released a new version of their internet telephony software. Use the action below to update Skype to the latest version (8.31.0.92).

Note: Affected computers may report back as 'Pending Restart' once the update has run successfully, but will not report back their final status until the computer has been restarted.

Important Note: The Skype update will automatically shut down all running instances of Skype. To prevent this behavior, you may want to deploy this action with the user constraint "Run only when no user is present" or display a message box before action execution instructing the user to shut down Skype before applying this update.
