Preface
PowerShell is an object-oriented scripting language aimed at systems administrators that was invented by Jeffrey Snover. PowerShell was first conceived as far back as 2002 and entered mainstream use in 2006. Exchange 2007 was one of the first major systems to adopt it as an administration language.
PowerShell has come a long way over the years. PowerShell 7 smooths over a lot of the rough edges in the original releases of the cross-platform PowerShell Core (PowerShell 6).
Like any good scripting language, PowerShell is the glue that ties automated processes together. It is a vital part of the Microsoft ecosystem and is great in heterogeneous environments.
