In addition to the regular supported running techniques, the Prolonged Security Updates (ESUs) for Windows 7 and Server 2008/2008 R2 will be introduced as standard. Net Explorer updates must demonstrate up once more this thirty day period as it appears to be receiving more interest by Microsoft of late.
