MSIX is a brand new application package created by Microsoft. The February version of 2019 is available for testing to anyone who wants to become insiders in the company program.
MSIX is a new packaging tool that combines the capabilities of the format used by the Store (.appx) applications and the classic Microsoft MSI file format. The new MSIX format supports all types of Windows applications, including desktop applications (Win32), .NET applications, and storage applications (UWPs) that use AppX.
According to Microsoft, the format of the MSIX package:
- It inherits the functions of UWP.
- Supports customization of applications.
- It has more packet security options.
- Supports all Windows applications.
MSIX also achieves the form of packaging and distribution used from App-V. This form of application packaging can be converted to Desktop App Converter, which allows the packaging of classic Win32 applications for deployment through the Microsoft Store.
Like the Desktop App Converter, and MSIX applications can have updates and are easy to install and remove. When you uninstall such an application, all of its components will be removed without leaving any data on your computer. But the cost is that it comes as a larger package size of the application.
The MSIX tool enables you to update the existing win32 application packages in the MSIX format. The first version of the MSIX Packaging Tool Insider is now available.
