Modifying the PATH in Powershell
From MyWiki
If, some time during a PowerShell session, you need to modify the PATH environment variable temporarily, you can do it this way $env:Path = $env:Path + ";C:\Program Files\GnuWin32\bin" Or even shorter as per Kevin’s comment $env:Path += ";C:\Program Files\GnuWin32\bin" $env:Path = "C:\cygwin64\bin;" + $env:Path ### didn't work for me
