WINDOWS COMMAND-LINE COMMANDS & TOOLS

PowerShell Commands

Windows Powershell Commands & Examples - All Windows Versions

Here are a bunch of Powershell commands that work in most, if not all, versions of Windows. Of course, the newer the version of Windows, the more command there are available, and the way they are used sometimes also has changed. This is where the Windows built-in "Get-Help" commandlet comes in handy. It is similar to the built-in "man",(short for "MANUAL"), as it's available via the command line for most commands.

Windows Version On the topic of what Powershell commands are available on which versions of Windows, this first section goes over the different methods of finding out exactaly which version of Windows you are dealing with.

  • Get-ComputerInfo
    • This get's the Windows version as seen by HAL, the Hardware Abstraction Layer:
PS C:\Users\jamie.DAWGLAND> Get-ComputerInfo | select WindowsProductName, WindowsVersion, OsHardwareAbstractionLayer

WindowsProductName             WindowsVersion OsHardwareAbstractionLayer
------------------             -------------- --------------------------
Windows Server 2022 Datacenter 2009           10.0.20348.558


PS C:\Users\jamie.DAWGLAND>



  • Get-ItemProperty
    • This command get's the value of the current version in the Windows Registry:
PS C:\Users\jamie.DAWGLAND> (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").ReleaseId
2009
PS C:\Users\jamie.DAWGLAND>



  • systeminfo
    • The "systeminfo" command retrieves a ton of information about the OS and hardward. In this example, I use the "findstr" command to pipe the output of the systeminfo command into findstr to only retreive lines that contain the string "OS", as seen here:
PS C:\Users\jamie.DAWGLAND> systeminfo | findstr OS       
OS Name:                   Microsoft Windows Server 2022 Datacenter
OS Version:                10.0.20348 N/A Build 20348
OS Manufacturer:           Microsoft Corporation
OS Configuration:          Primary Domain Controller
OS Build Type:             Multiprocessor Free

PS C:\Users\jamie.DAWGLAND>



  • [System.Environment]::OSVersion.Version
    • Pull the Windows version from the system's environtment variables:
PS C:\Users\jamie.DAWGLAND> [System.Environment]::OSVersion.Version

Major  Minor  Build  Revision
-----  -----  -----  --------
10     0      20348  0

PS C:\Users\jamie.DAWGLAND>



  • Get-ComputerInfo -Property Windows*
    • Using the * wild-card to grab the actually pertinent information with one command:
PS C:\Users\jamie.DAWGLAND> Get-ComputerInfo -Property Windows*

    • Last, but not least:

Reading Windows Registry Values to Get System Info & to Use in Scripts!

  • Reading registry values from the commandline(CMD):
    • Syntax:
REG QUERY [ROOT\]RegKey /v ValueName [/s] 
REG QUERY [ROOT\]RegKey /ve --This returns the (default) value
Where RegKey is the key which needs to be searched for in the registry.
  • Example
@echo off 
REG QUERY HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows\

The above command will query all the keys and their respective values under the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows\

This location in the registry has some key information about the windows system such as the System Directory location.

  • Example output from above "REG QUERY" command:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows
   Directory REG_EXPAND_SZ %SystemRoot%
   SystemDirectory REG_EXPAND_SZ %SystemRoot%\system32
   NoInteractiveServices REG_DWORD 0x1
   CSDBuildNumber REG_DWORD 0x4000
   ShellErrorMode REG_DWORD 0x1
   ComponentizedBuild REG_DWORD 0x1
   CSDVersion REG_DWORD 0x0
   ErrorMode REG_DWORD 0x0
   CSDReleaseType REG_DWORD 0x0
   ShutdownTime REG_BINARY 3AFEF5D05D46D101

Query Detailed System Information - Here is an example of how to obtain detailed system information about the server you are currently working on:



SConfig						Start Server Configuration text-mode command-line tool for Server Core without GUI

If you’re intending to use key based, rather than password based, authentication, you should also run the following command on the server to install an OpenSSH related PowerShell module that includes tools to help you configure that functionality:

Install-Module -Force OpenSSHUtils -Scope AllUsers

To install NANO text editor, as per URL this is based on (I prefer the VI/VIM text editor, which is included with the GitHub command-line client, which also provides basic BASH shell functionality and tools and support for the built-in Windows OpenSSH Server & Clients!
