Powershell tries to solve few of the problems. Powershell 2.0 supports registry, processes, services, event logs etc. Powershell 3.0 with windows 8 and server 2012, introduced hardware inventory access as storage and network adapters.<\/p>\n\n\n\n<p><strong>Powershell is easy<\/strong><\/p>\n\n\n\n<p>Windows powershell used&nbsp;Get-WmiObject which simplified WMI.&nbsp;It saves minimum of 7 lines\/vbscripts\/perl script as compared to WMI. The single-line commands in powershell are also called cmdlets.&nbsp;The underlying technology of Powershell is still WMI, but the classes are basically wrapped and exposed as functions that behave like Windows PowerShell cmdlets<\/p>\n\n\n\n<p><strong>Powershell can access the below modules \u2013<\/strong><\/p>\n\n\n\n<ul><li><strong>WMI<\/strong>\u2013 Windows Management Instrumentation. It is the Microsoft implementation of&nbsp;<a href=\"https:\/\/anakage.com\/\" rel=\"noopener\">Web-Based Enterprise Management<\/a>&nbsp;(WBEM) allowing access to data. WMI uses the Common Information Model (CIM) to describe objects such as systems, applications, network equipment.<\/li><li><strong>CIM<\/strong>\u2013 Common Information Model. It is a set of standards that describes how information is structured and represented at the heart of the system. It was created by the DMTF (Distributed Management Task Force), a working group to which Microsoft belongs.<\/li><li><strong>PSWA<\/strong>\u2013 PowerShell Web Access. This new function allows secure access to a Windows PowerShell console from a browser so as to interact with any system, even if it is outside the domain.<\/li><\/ul>\n\n\n\n<p><strong>Sample commands in WMI vs Powershell \u2013<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>WMIC Version<\/strong><\/td><td><strong>Windows Powershell Version<\/strong><\/td><\/tr><tr><td>wmic bios get caption, manufacturer, smbiosbiosversion, version<\/td><td>get-wmiobject win32_bios caption, manufacturer, smbiosbiosversion, version<\/td><\/tr><tr><td>&nbsp;wmic logicaldisk where drivetype=3 get name, freespace, systemname, filesystem, size, volumeserialnumber \/format:list<\/td><td>&nbsp;get-wmiobject win32_logicaldisk name, freespace, systemname, filesystem, size, volumeserialnumber -filter drivetype=3<\/td><\/tr><tr><td>&nbsp;wmic process call create \u2018notepad.exe\u2019<\/td><td>&nbsp;invoke-wmimethod win32_process -name create -argumentlist \u2018notepad.exe\u2019<\/td><\/tr><tr><td>&nbsp;wmic \/node:&lt;machine name&gt; \/user:&lt;username&gt;\/password:&lt;password&gt; logicaldisk where drivetype=3 get name, freespace,&nbsp;filesystem, size<\/td><td>&nbsp;Get-wmiobject -ComputerName &lt;machine name&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;-credential &lt;remote credentials&gt;&nbsp;win32_logicaldisk name, reespace, systemname, filesystem, size, volumeserialnumber&nbsp;&nbsp;-filter drivetype=3<\/td><\/tr><tr><td>&nbsp;WMIC&nbsp;PROCESS&nbsp;where name=\u2019notepad.exe\u2019 delete<\/td><td>&nbsp;gwmi win32_process -filter \u201cname=\u2019notepad.exe\u2019\u201d | remove-wmiobject<\/td><\/tr><tr><td>&nbsp;wmic ENVIRONMENT SET NAME=\u201dTEMP\u201d, VARIABLEVALUE=\u201dNEW\u201d , username=\u201d&lt;system&gt;\u201d<\/td><td>&nbsp;gwmi win32_environment -filter \u2018Name=\u201dtestvar\u201d and username=\u201d&lt;system&gt;\u201d\u2018 | set-wmiinstance -argument @{variableValue=\u201dtestvalue\u201d}<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Advantages of Powershell<\/strong><\/p>\n\n\n\n<ul><li>Powershell has&nbsp;<strong>access to all .NET libraries<\/strong>&nbsp;in addition to the items mentioned above so you can take advantage of anything you could with a language like C# or VB.NET.<\/li><li>Powershell often allows you to&nbsp;<strong>do more with less<\/strong>&nbsp;compared to VBscript.
