Windows PowerShell is Microsoft's task automation framework, consisting of a command-line shell and associated scripting language built on top of, and integrated with the .NET Framework. PowerShell provides full access to COM and WMI, enabling administrators to perform administrative tasks on both local and remote Windows systems.
In PowerShell, administrative tasks are generally performed by cmdlets (pronounced command-lets), specialized .NET classes implementing a particular operation. Sets of cmdlets may be combined together in scripts, executables (which are standalone applications), or by instantiating regular .NET classes (or WMI/COM Objects). These work by accessing data in different data stores, like the filesystem or registry, which are made available to the PowerShell runtime via Windows PowerShell providers.
Windows PowerShell also provides a hosting mechanism with which the Windows PowerShell runtime can be embedded inside other applications. These applications then leverage Windows PowerShell functionality to implement certain operations, including those exposed via the graphical interface. This capability has been utilized by Microsoft Exchange Server 2007 to expose its management functionality as PowerShell cmdlets and providers and implement the graphical management tools as PowerShell hosts which invoke the necessary cmdlets. Other Microsoft applications including Microsoft SQL Server 2008 also expose their management interface via PowerShell cmdlets. With PowerShell, graphical interface-based management applications on Windows are layered on top of Windows PowerShell. A PowerShell scripting interface for Windows products is mandated by the Common Engineering Criteria.
Windows PowerShell includes its own extensive, console-based help, similar to man pages in Unix shells via the Get-Help cmdlet

Better option: (you will get a confirmation warning with this mode)

Stop on Error
To make powershell stop executing whenever it encounters error, set
$ErrorActionPreference = "Stop" # or Get-Process -ErrorAction Stop
Redirection
null:
# technically any non assigned variable will work the same echo "Hello world" > $null # redirect to like /dev/null

Steal pop up dialog box from visual basic: [8] (did not work for me!)

Input Box [9] (works):
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') | Out-Null
$computer = [Microsoft.VisualBasic.Interaction]::InputBox("Enter a computer name", "Computer", "$env:computername")
All user input and output normally occurs inside the PowerShell console. Simply access the .NET framework directly if you'd like to get back the same dialogs VBScript scripters are using. Here is the old-fashioned InputBox:

-PSConsoleFile
Loads the specified Windows PowerShell console file. To create a console
file, use Export-Console in Windows PowerShell.
-Version
Starts the specified version of Windows PowerShell.
-NoLogo
Hides the copyright banner at startup.
-NoExit
Does not exit after running startup commands.
-Sta
Start the shell using a single-threaded apartment.
-NoProfile
Does not use the user profile.
-NonInteractive
Does not present an interactive prompt to the user.
-InputFormat
Describes the format of data sent to Windows PowerShell. Valid values are
"Text" (text strings) or "XML" (serialized CLIXML format).
-OutputFormat
Determines how output from Windows PowerShell is formatted. Valid values
are "Text" (text strings) or "XML" (serialized CLIXML format).
-WindowStyle
Sets the window style to Normal, Minimized, Maximized or Hidden.
-EncodedCommand
Accepts a base-64-encoded string version of a command. Use this parameter
to submit commands to Windows PowerShell that require complex quotation
marks or curly braces.
-File
Execute a script file.
-ExecutionPolicy
Sets the default execution policy for the session.
-Command
Executes the specified commands (and any parameters) as though they were
typed at the Windows PowerShell command prompt, and then exits, unless
NoExit is specified. The value of Command can be "-", a string. or a
script block.
If the value of Command is "-", the command text is read from standard
input.
If the value of Command is a script block, the script block must be enclosed
in braces ({}). You can specify a script block only when running PowerShell.exe
in Windows PowerShell. The results of the script block are returned to the
parent shell as deserialized XML objects, not live objects.
If the value of Command is a string, Command must be the last parameter
in the command , because any characters typed after the command are
interpreted as the command arguments.
To write a string that runs a Windows PowerShell command, use the format:
"& {<command>}"
where the quotation marks indicate a string and the invoke operator (&)
causes the command to be executed.
-Help, -?, /?
Shows this message. If you are typing a PowerShell.exe command in Windows
PowerShell, prepend the command parameters with a hyphen (-), not a forward
slash (/). You can use either a hyphen or forward slash in Cmd.exe.
EXAMPLES
PowerShell -PSConsoleFile SqlSnapIn.Psc1
PowerShell -version 1.0 -NoLogo -InputFormat text -OutputFormat XML
PowerShell -Command {Get-EventLog -LogName security}
PowerShell -Command "& {Get-EventLog -LogName security}"
# To use the -EncodedCommand parameter:
$command = 'dir "c:\program files" '
$bytes = [System.Text.Encoding]::Unicode.GetBytes($command)
