Microsoft Intune – New Updates in PowerShell Scripts

Microsoft Intune is one of those brilliant products that has helped to optimize IT infrastructure for many businesses. It’s a platform that can transform your business into a modern workplace. And its capabilities are almost without limit. If you want to upload PowerShell scripts in Intune, there is the Microsoft Intune management extension (IME) that you can use for that. This management extension can enhance Mobile Device Management (MDM) resulting in a simpler move to modern management. With all this done, you can then run these scripts on Windows 10 devices. PowerShell scripts are important in a lot of different use cases and this blog is going to take a look at what this technology can do.

What is PowerShell?

PowerShell is a scripting and automation platform belonging to Microsoft. It’s an amazing product that is both a scripting language as well as an interactive command environment that is built on the .NET framework. Released back in 2006, PowerShell was basically a replacement for Command Prompt as the default method for automation of batch processes and creation of customized system management tools. PowerShell can easily automate laborious admin tasks by combining commands known as cmdlets and creating scripts. Available in all Windows OS starting with Windows 2008R2, PowerShell plays a huge role in helping IT professionals configure systems.

Adopting modern management

Modern workplaces now have plenty of user and business-owned platforms allowing users to work from anywhere. With MDM services like Microsoft Intune, you can manage devices that are running Windows 10. The Windows 10 management client will communicate with Intune to run enterprise management tasks. Windows 10 MDM features will be supplemented by IME. With this in place, you can create PowerShell scripts to run on Windows 10 devices e.g, creating a PowerShell script that does advanced device configurations. Having done this, you can upload the script to Intune and assign the script to an Azure AD group. Then run the script. Moreover, you can monitor the run status of the script from start to finish.

Latest updates from Microsoft

In November 2020, Microsoft announced the general availability of PowerShell 7.1 which is built on the foundation of PowerShell 7.0. The goal was to bring about improvements and fixes to the existing technology. Some of these features, updates, and breaking changes include:

  • PSReadLine 2.1.0, including Predictive IntelliSense
  • PowerShell 7.1 has been published to the Microsoft Store
  • Installer packages have been updated for new operating system versions with support for ARM64
  • 4 new experimental features and 2 experimental features promoted to mainstream
  • A number of breaking changes that improve usability

Using scripts in Intune

Before IME can automatically install when a PowerShell script or Win32 app is assigned to the user or device, a few prerequisites should be met:

  • Windows 10 version 1607 or later, Windows 10 version 1709 or later for devices enrolled using bulk auto-enrollment.
  • Devices joined to Azure AD including Hybrid Azure AD-joined which consists of devices that are joined to Azure AD, and are also joined to on-premises Active Directory (AD).
  • Devices enrolled in Intune namely devices enrolled in a group policy, devices that are manually enrolled in Intune, and co-managed devices that use both Configuration Manager and Intune.

Script policy creation

Start by signing in to the Microsoft Endpoint Manager admin center. From there you’ll select Devices then PowerShell scripts then add. Under Basics, you will then have to provide a name and a description for the PowerShell script. Next, you go to Script settings and you’ll have to enter the required properties. After that, you select Scope tags, however, these are optional. And then select Assignments > Select groups to include and an existing list of Azure AD groups will be shown. Lastly, in Review + add, you’ll see a summary of the settings you configured. Select Add to save the script. When you have done so, the policy is deployed to the groups you chose.

Important considerations

If you have scripts that are set to user context with the end-user having admin rights, by default, the PowerShell script runs under the administrator privilege. Also, end-users don’t need to sign in to the device to execute PowerShell scripts. The IME agent checks with Intune once per hour and after every reboot for any new scripts or changes. In the event of a script failing, the agent attempts to retry the script three times for the next 3 consecutive IME agent check-ins. And as far as shared devices are concerned, the PowerShell script runs for every new user that signs in.

PowerShell scripts limitations

Although with Microsoft Intune you can deploy PowerShell scripts to Windows 10 devices, there are a few limitations worth noting. These include: 

  • You won’t get support for running PowerShell scripts on a scheduled basis.
  • Although you can see whether the PowerShell script execution succeeded or failed, the output generated is only available on the endpoint that executes it and is not returned to the MEM Admin Portal.
  • Since executed PowerShell scripts are visible in the Intune Management Extension log file as plain text, credentials can’t be passed securely.
  • The Intune Management Extension agent responsible for executing PowerShell scripts on the endpoints only checks once an hour for new scripts so there is a delay with execution.

Wrap up

Maximizing the time we have is increasingly a massive concern for most organizations. Technological innovation has made it such that we can have more productive time on our hands. PowerShell is a product that is very useful to IT professionals for overall system management. By being able to automate the administration of Windows OS and other applications, organizations can operate more efficiently. The evolution of this platform since its release fourteen years ago has seen it grow from strength to strength. Undoubtedly, this is a product that can easily boost your productivity.
