Introduction

PowerShell is the scripting language now embedded into every Microsoft business software product, allowing seemingly simple commands to expose powerful, automated solutions. For many Microsoft products, PowerShell is required to control, extend and manage various processes. PowerShell can be used to initiate simple tasks and inquiries and can also be strung together to automate more complex sets of operations, for instance within a private cloud environment. In the past, various scripting languages required months of study to do simple things, but PowerShell has changed all of that. Learning PowerShell seems extremely daunting to some, but once study starts, users find the simplicity to be refreshing.

PowerShell is a hugely powerful (pun intended) scripting language and Microsoft has invested a lot of resources and support behind making it an integrated part of every piece of the company's software offerings. It's really nothing to be afraid of and those that start down the path to learning find it simple and easy to understand. And, as the education progresses, it gets easier and easier.

This guide is intended to help IT professionals build a relationship with PowerShell, and aid in understanding how powerful simple, one-line commands can be.

Run the Access Control App to Configure Windows Remote Management with PowerShell

PowerShell is powerful, for sure. But, with that power comes great, uh, responsibility. Part of that responsibility is ensuring commands can be run remotely, and by the right people. If you need to adjust the Access Control List for utilizing PowerShell commands on remote computers, you'll first need to know how to open the UI for managing and modifying the ACLs.

Do this:

1. As an Administrator, run the following at a PowerShell prompt:

Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell ?Force

2. You'll be prompted to ensure that the WinRM service is running. Answer "Y" (Yes) to start the Windows service.

3.Once the service is started the Access Control applet will run, allowing you to make modifications:

We'll go deeper into PowerShell remoting in future articles, but, this will get you started down the path and give you another "cool thing" to know.
