Path Environment Variable Windows 10. Echo %Path% on command prompt shows only %Path% [duplicate]

PowerShell uses a different syntax than Windows Command Prompt.

Use $Env:Path or Get-ChildItem Env:Path to retrieve the PATH variable.

Since Windows 10 Insider Build 14971 Microsoft changed the default command shell to be PowerShell instead of cmd.

PowerShell handles environment variables differently to cmd.

To display their values in PowerShell use the following syntax:

$Env:variablename

Example:

> echo %Path%
%Path%
> $Env:Path
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\apps\WSCC\Sysinternals Suite;C:\apps\WSCC\NirSoft Utilities
