Install and Configure Powershell Web Access on Windows Server

What is PowerShell Web Access?

Windows PowerShell® Web Access, first introduced in Windows Server® 2012, acts as a Windows PowerShell gateway, providing a web-based Windows PowerShell console that is targeted at a remote computer. It enables IT Pros to run Windows PowerShell commands and scripts from a Windows PowerShell console in a web browser, with no Windows PowerShell, remote management software, or browser plug-in installation necessary on the client device. -https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831611(v=ws.11)
