Application Packaging itself is just a small step within the whole process, starting with the application being requested by the business, and resulting in a finished product that is rolled out to production devices.

Lessons I have learned from making many mistakes in my enterprise software packaging newbie (and not only) years.

For those new to Windows deployment/management, Windows Installer is Microsoft's solution used for the installation, removal, but also maintenance of software. Windows Installer was released for the first time when Windows 95 came in and has been developed over time since then.

We know 13th Jan 2015 is the date when Microsoft's mainstream support for Windows 7 ended. Since then, Microsoft has continued to provide security updates for free and will do this until 14th Jan 2020 when Windows 7 extended support is going to end. As it has done with previous versions of Windows, the only people who will receive extended security updates (ESUs) after Jan 2020 will be those willing to pay for them.
