What's new in PowerShell 7

What’s new in PowerShell 7 – Check it out!

As you know, the PowerShell team just released the new PowerShell version called PowerShell 7. PowerShell 7 will brings a couple of new features and enhancements not only for users who used PowerShell Core 6 but also for people who are currently using Windows PowerShell 5.0. I want to quickly give you an overview of what’s new in PowerShell 7.

New feature enhancements – What’s new in PowerShell 7

There are many enhancements in PowerShell 7 to make it the best PowerShell version yet. It is almost impossible to list all of them in one single blog post, so I will focus on the once, which are the most important once for me.

Out-GridView, -ShowWindow and other GUI cmdlets are back on Windows

With .NET Core 3 brining back WPF support on Windows, the PowerShell team was able to bring back some of the popular graphical tools and cmdlets like Out-Gridview, Show-Command, and the Get-Help -ShowWindow.

ForEach-Object -Parallel

Since I started using PowerShell and get into working with objects, ForEach-Object was one of the most critical cmdlets. By adding the -Parallel parameter to the ForEach-Object cmdlet, you can execute a scriptblock in parallel, similar to the option we had with PSWorkflow. With that performance can get so much better if you are working with a broad set of objects. You can also optionally set the maximum threads, which will be used in parallel (the default thread count is set to 5) with the -ThrottleLimit parameter.

Hyper-V VM Configuration Version

Hyper-V VM configuration version supported features

A couple of months ago, I wrote an article about the new Microsoft Hyper-V UEFI in Windows Server 2019 and Windows 10 virtual machines. With that version Microsoft also released a new Hyper-V VM configuration version 9.0. This is not unusual, the Hyper-V teams usually bumps up the version number from release to release, since new Hyper-V features are introduced. In the comments, the question came up, what is new in this version of the Hyper-V VM configuration, Since the version was still a preview release of Windows Server and Windows 10, Microsoft didn’t share the full list of features per configuration version. However, now the documentation is ready and you can find the documentation here.

Supported features

The following table shows the minimum virtual machine configuration version required to use some Hyper-V features.

How to upgrade Hyper-V VM configuration version

Hyper-V vNext Update VM Configuration Version

Upgrading the Hyper-V VM version is pretty straight forward. If the VM is running on a host supporting a newer version of Hyper-V VMs, you can right click the virtual machine in the Hyper-V Manager and click on upgrade or you can run the Update-VMVersion PowerShell cmdlet.


I hope this blog was help full for understanding Hyper-V VM versions, let me know if you have any questions in the comments!

OpenSSH Windows 10

Install SSH on Windows 10 as Optional Feature

On Windows 10 you have already a couple of options to run SSH commands. You can use for example the PowerShell Module Posh-SSH or use the Windows Subsystem for Linux (WSL) or use third party tools like PuTTY.

Today my colleague Raphael Burri from itnetX mentioned that with the latest Windows 10 release, the Fall Creators Update (10.0.16299), there is another option to use SSH on Windows 10. It looks like you can now install a beta version of OpenSSH on Windows 10 as an optional feature.

Install SSH on Windows 10

Just go to the Settings App > Apps > Settings & Apps > Manage Optional Features > Add Feature and select the OpenSSH Client Beta and as you can see, you also have OpenSSH Server (Beta) available.

Add a feature OpenSSH Windows 10

You can also using PowerShell to install it:

Get-WindowsCapability -Online | ? Name -like 'OpenSSH*'
# Install the OpenSSH Client
Add-WindowsCapability -Online -Name OpenSSH.Client~~~~
# Install the OpenSSH Server
Add-WindowsCapability -Online -Name OpenSSH.Server~~~~

After installing the optional feature OpenSSH Client, you can now use the SSH client from PowerShell or the Command Prompt

OpenSSH Windows 10

It is great to see Microsoft integrating even more options for SSH on Windows 10. I hope this posts helps you how to install SSH on Windows 10.

Windows 10 Task View

The best Windows 10 Features – Why you will love Windows 10

Since the first release of the Windows 10 Preview in the Insider program, I was using the Technical previews on my Surface Pro 3, and it is excellent how Microsoft is improving Windows 10 over the last several months based on research and feedback from the Windows Insider program.

In some days, on July 29, Microsoft will release Windows 10 to the public, and here are some reasons why you will love Windows 10:

Microsoft Edge

Microsoft Edge Browser

With Windows 10 Microsoft released a new browser called Microsoft Edge (before Project Spartan) which is amazingly fast and brings a lot of new features to the table such as Cortana Integration, Web notes which allow you basically draw your notes on websites and share them and Microsoft also promised to enable browser extensions. Secret: you can also switch from a Light Theme to a Dark Theme.

You can also check out the new edge insider preview here: Microsoft Edge Insider

Task View & Virtual Desktop

Windows 10 Task View

Most of the IT Pros reading this blog already knew about Task view in the previous version of Windows using WIN + TAB, but only a few other users did know about these features. Microsoft not only improved the Task view, but Microsoft also promoted it much better with an icon in the Taskbar.

In Windows 10 WIN + TAB does not only offer you Task View it also allows you to create and switch between Virtual Desktops. With Virtual Desktops, you can now finally create multiple workspaces on your PC, which should bring you the productivity boost you need. Secret: You can switch between different Desktops using the Shortcut: CTRL + WIN + ARROW (LEFT and RIGHT).


Hyper-V vNext Runtime Memory Resize

Microsoft builds Hyper-V directly into the Windows Client since Windows 8. This is great if you want to run Virtual Machines on your Windows Client. Windows 10 Client Hyper-V brings you the excellent performance and features Windows Server 2016 Hyper-V will bring you. Of course, some features are only available in the server build of Hyper-V, but you get some great features such as Enhanced Session mode to copy & paste between your PC and your Virtual Machine. Secret: Windows 10 will allow you to run Hyper-V and use Connected Standby at the same time.
