Since it is a preview version, you may experience some anomalies. There is currently one known issue where the Alpine Linux packages are missing powershell.config.json which disables the experimental features by default. If you already have a stable version of Windows PowerShell running on your machine, installing the preview version will not affect it and both could run simultaneously. However, in case an older preview version of PowerShell is installed, it will be automatically overwritten with the newer preview version. While installing PowerShell, you will be given the option to choose whether to update it via Microsoft Update or WSUS. However, it will have no effect since the preview version needs to be manually installed. Since you already know the known issue with this release, let us see what new features it brings before you install it.

Final Thoughts
We recommend that you install all preview releases by Microsoft in a test environment, for example on a virtual machine, and not on production environments. This is because preview releases are meant for testing purposes so that Microsoft can fix any issues that they missed based on the user’s feedback. Also see:
