+# What is Windows PowerShell?
+
+_**Windows PowerShell**_ and _**PowerShell**_ are two separate products.
+
+- _**Windows PowerShell**_ is the version of PowerShell that ships in Windows. This version of
+  PowerShell uses the full .NET Framework, which only runs on Windows. The latest version is Windows
+  PowerShell 5.1. Microsoft is no longer updating Windows PowerShell with new features. Support for
+  Windows PowerShell is tied to the version of Windows you are using.
+
+- _**PowerShell**_ is built on the new versions of .NET instead of the .NET Framework and runs on
+  Windows, Linux, and macOS. Support for PowerShell is based on the version of .NET that it was
+  built on. For more information about the support lifecycle for PowerShell, see the
+  [PowerShell support lifecycle][02] documentation.
+

+- For information about migrating from Windows PowerShell to PowerShell, see
+  [Migrating from Windows PowerShell 5.1 to PowerShell 7][04].
+- For more information about previous versions of Windows PowerShell, see
+  [Previous versions of PowerShell][05].
+- For more information about the terminology used in PowerShell documentation, see
