function Get-PEB
{
<#
.SYNOPSIS
Returns the process environment block (PEB) of a process.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: Get-PEB.format.ps1xml
.DESCRIPTION
Get-PEB returns a fully parsed process environment block (PEB) of any process. Because the PEB and its underlying structure differ according to OS version and architecture, Get-PEB builds the PEB dynamically at runtime. Get-PEB is designed to work in Windows XP - Windows 8 32/64-bit. It will also return the PEB of Wow64 processes.
.PARAMETER Id
The process ID of the process whose PEB will be retrieved.
.EXAMPLE
$AllPEBs = Get-Process | Get-PEB
Description
-----------
Get the PEB of every process. Note: To get the PEBs for all processes, run this command from an elevated instance of PowerShell
.EXAMPLE
C:\PS> $NotepadPEB = Get-PEB -Id (ps notepad)
C:\PS> $NotepadPEB.InInitializationOrderModuleList
Description
-----------
Display all loaded modules of the notepad process in initialization order.
.NOTES
Some processes will not issue a handle unless you are running Get-PEB from an elevated instance of PowerShell.
