PowerShell is a command line and scripting language that provides native access to .NET classes, COM objects, WMI, and XML. It allows administrators to leverage these APIs and formats output for improved productivity. The document demonstrates PowerShell's ability to investigate systems, manipulate and transform objects, and access existing instrumentation through demos. It provides resources for learning PowerShell including documentation, books, community forums, and code repositories.

17. PowerShell provides native access to any .NET class Create any object [reflection.assembly]::LoadWithPartialName("System.Windows.Forms") $d = New-Object System.DateTime 2006,12,25 Access Properties/Invoke Methods $d.DayOfWeek $d.AddDays(-30) Access Statics [DateTime]::Now [DateTime]::IsLeapYear(2008) Scripting with .NET Allows admins to easily access and leverage a huge API set because of scriptability, utilities and formatting

19. Access existing instrumentation Bind to COM objects $fso = New-Object -ComObjectScripting.FileSystemObject $m = [System.Runtime.InteropServices.Marshal] $word = $m::GetActiveObject("Word.Application") Invoke methods/access properties $fso.GetDrive(“C:”) $fso.VolumeName = “System Drive” Manipulate and format results Define and import custom formating Update-FormatData Office.Word.Format.ps1xml $word.RecentFiles | Sort name | Format-Table Scripting with COM Allows more simpler/more powerful COM scripts because of utilities and formatting

20. PowerShell provides native WMI support Get-WmiObject Allows for inspection of WMI namespace Get-WmiObject –list [-Namespace xx] Get-WmiObject –Class xx –Namespace xx –Property xxx – Filter xxx –ComputerName xxx –Credential xxx Native language support [WMI] “JPSDESK10ootimv2:Win32_Process.Handle="0“ [WMICLASS] "ROOTimv2:WIN32_PROCESS" [WMISEARCHER]"select * from Win32_process WHERE Name = 'calc.exe'" Scripting with WMI
