Introduction

Powershell has evolved over the years, with some old functionality not working in later versions.

If you have created a script in Powershell v1 or v2, it might not work with Powershell v3 or later. It is possible using a simple command to change the Powershell version.

Which version of Powershell you are running depends on the installed Windows version.

The general recommendation is to update your environment to the latest version of Powershell, so all scripts are created for the same version. Talking from experience, failure to do so will cause a lot of issues.

In this blog post, I cover how to run the Powershell window using another version.

How to check the version of Powershell

To check the Powershell version, open a Powershell command prompt, and enter:

$PSVersionTable
Check Powershell version using PSVersionTable

How to change to another version of Powershell

To change the version to v2, enter this command on a machine:

powershell -version 2.0

Update environment to latest Powershell version

Unless you have a good reason not to, I highly recommend upgrading all your machines in your environment to the latest Powershell version.

One way of doing this is through MEMCM (SCCM). Just create an application with the latest Windows Management Framework (WMF), and deploy it to your clients.

Conclusion

Changing the version of Powershell will be required in some cases, but in most cases you should upgrade all clients to the latest version of Powershell.
