How to upgrade PowerShell version from 2.0 to 3.0

Download and install from http://www.microsoft.com/en-us/download/details.aspx?id=34595. You need Windows 7 SP1 though.

It's worth keeping in mind that PowerShell 3 on Windows 7 does not have all the cmdlets as PowerShell 3 on Windows 8. So you may still encounter cmdlets that are not present on your system.


The latest PowerShell version as of Sept 2015 is PowerShell 4.0. It's bundled with Windows Management Framework 4.0.

Here's the download page for PowerShelll 4.0 for all versions of Windows. For Windows 7, there are 2 links on that page, 1 for x64 and 1 for x86.

Just run this in a console.

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
cinst powershell

It installs the latest version using a Chocolatey repository.

Originally I was using command cinst powershell 3.0.20121027, but it looks like it later stopped working. Since this question is related to PowerShell 3.0 this was the right way. At this moment (June 26, 2014) cinst powershell refers to version 3.0 of PowerShell, and that may change in future.

See the Chocolatey PowerShell package page for details on what version will be installed.


  1. Install Chocolatey
  2. Run the following commands in CMD

    • choco install powershell

    • choco upgrade powershell
