After some recent blog post, where I posted some screenshots of my PowerShell console, some people were asking about how I made the background of the PowerShell console transparent. Well this is very simple, Microsoft changes a lot on the Command Prompt and PowerShell in Windows 10.
Simply right click on the title bar of the PowerShell console or CMD console and click on properties.
Now in the Colors tap you can change the transparency of the console window using the opacity slider.
This also works with the command prompt (CMD) on Windows 10.
