History and role

The Msiexec.exe process program file is a system process defined by Microsoft for its published Windows operating system (Windows 2000), officially described as: Windows Installer or Windows Installer, Its main function is to install new programs. When Msiexec.exe is called by the installer, it reads the package file (. msi) with Msi.dll, applies the transform file (. mst), and merges the command-line options provided by the installer. Windows Installer performs all installation-related tasks: including copying files to the hard disk, modifying the registry, creating a desktop shortcut, and displaying a prompt dialog box if necessary for the user to enter installation preferences. Typically, Msiexec.exe is started when Microsoft updates, upgrades, or some software is installed, and the user can see through the Task Manager that the process is running in the background with a lot of memory and CPU usage.
