Having a transparent PowerShell Window not only makes you look cool, but it is actually very helpful. You have the ability to reference information in another shell, or a webpage, without having to switch back and forth between windows.
I am going to show you how to set opacity in PowerShell v5 because it is a built-in feature. There is a way to create a transparent PowerShell window in older versions, but it requires editing the registry and taking advantage of the Windows Aero theme.
To check your PowerShell version number, run $PSVersionTable in PowerShell and it will be listed under PSVersion.
How to make your PowerShell Window transparent
As stated above, you will need PowerShell Version 5 to follow these steps.
1) Open a PowerShell console window.
2) Right click the title bar, and select "Properties."
3) Select the "Colors" tab
4) You will then see the opacity slider at the bottom of the window.
I recommend setting it to 85%.
