Microsoft has published a preview of the “Technical Requirements for the Windows 7 Software Logo Program for Client Operating Systems”. The list of requirements is significantly shorter than in previous versions of Windows. The use of Windows Installer (MSI) or ClickOnce is no longer listed as an explicit requirement. Software developers can now self-test their application for compatibility, external test centers are no longer involved in the process. Instead they have to give a copy (and license) of their application to Microsoft for testing purposes.
