What is MSU file?
MSU file extension is a type of archive file that contains the Windows Vista Update Package. The MSU file extension is also known as an update package or similar terms. Once you open an MSU file, you will see the contents of the Windows Vista Update Package and how it looks like before it's installed on your computer. The .MSU file extension was first used by Microsoft to create the Windows Vista Update Package that was required to install their operating system on computers running Windows XP. After Microsoft released this update package, they created a new folder called WindowsUpdateContent for this specific type of files rather than using .MSI for single-file installations of software applications. Microsoft once again uses this MSU format to distribute updates with patches and fixes, which are needed for keeping your computer up
