I’ve just found that Microsoft has just released a repository for all scripts which are driven by Technet script repository and Microsoft Customer Script & Support, the sample scripts are based on the real world scenario which are expected to save the IT admin/developer to reinvent the wheel for a particular task and instead they can build upon it or modify it. The repository covers sample for Microsoft Office, Microsoft SQL Server, Microsoft Exchange, Microsoft Sharepoint, Microsoft Windows 7, Microsoft Windows Server 2008 and Office 365
