App Installer is a software component of Windows 10, introduced in the 2016 Anniversary Update, used for the installation and maintenance of applications packaged in .appx or .appxbundle installation packages; they are loosely relational databases with an XML app manifest.[2] The .appx and .appxbundle files contain either a Win32 or a Universal Windows Platform app, icons for the Start menu and taskbar, a virtualized version of any Windows Registry keys needed, and any other assets needed for the installed app to function.[3]
