function Get-CSRegistryAutoStart {
<#
.SYNOPSIS

List installed autostart execution points present in the registry.

Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause

.DESCRIPTION

Get-CSRegistryAutoStart lists autorun points present in the registry locally or remotely.

Get-CSRegistryAutoStart was heavily influenced by the great PowerShell autoruns function written by Emin Atac (@p0w3rsh3ll) - https://github.com/p0w3rsh3ll/AutoRuns. Emin's version is ideal for use locally and when PowerShell remoting is enabled. Get-CSRegistryAutoStart can retrieve autoruns information remotely from systems regardless of the presense of PowerShell.

Each switch argument in Get-CSRegistryAutoStart represents the corresponding tab in autoruns.exe.

.PARAMETER Logon

Retrieve logon artifacts

.PARAMETER LSAProviders

Retrieve LSA provider artifacts

.PARAMETER ImageHijacks

Retrieve image hijack artifacts

.PARAMETER AppInit

Retrieve appinit artifacts

.PARAMETER KnownDLLs

Retrieve KnownDLL artifacts

.PARAMETER Winlogon

Retrieve winlogon artifacts

.PARAMETER PrintMonitors

Retrieve print monitor artifacts

.PARAMETER NetworkProviders

Retrieve network provider artifacts

.PARAMETER BootExecute

Retrieve boot execute artifacts

.PARAMETER NoProgressBar
 
Do not display a progress bar. This parameter is designed to be used with wrapper functions.

.PARAMETER CimSession

Specifies the CIM session to use for this cmdlet. Enter a variable that contains the CIM session or a command that creates or gets the CIM session, such as the New-CimSession or Get-CimSession cmdlets. For more information, see about_CimSessions.

.PARAMETER OperationTimeoutSec

Specifies the amount of time that the cmdlet waits for a response from the computer.
 
By default, the value of this parameter is 0, which means that the cmdlet uses the default timeout value for the server.
 
If the OperationTimeoutSec parameter is set to a value less than the robust connection retry timeout of 3 minutes, network failures that last more than the value of the OperationTimeoutSec parameter are not recoverable, because the operation on the server times out before the client can reconnect.

.OUTPUTS

CimSweep.AutoRunEntry

Outputs objects representing autoruns entries similar to the output of Sysinternals Autoruns.

function Get-CSStartMenuEntry {
<#
.SYNOPSIS
 
List user and common start menu items.
 
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
 
.PARAMETER NoProgressBar
 
Do not display a progress bar. This parameter is designed to be used with wrapper functions.
 
.PARAMETER CimSession
 
Specifies the CIM session to use for this cmdlet. Enter a variable that contains the CIM session or a command that creates or gets the CIM session, such as the New-CimSession or Get-CimSession cmdlets. For more information, see about_CimSessions.
 
.PARAMETER OperationTimeoutSec

Specifies the amount of time that the cmdlet waits for a response from the computer.
 
By default, the value of this parameter is 0, which means that the cmdlet uses the default timeout value for the server.
 
If the OperationTimeoutSec parameter is set to a value less than the robust connection retry timeout of 3 minutes, network failures that last more than the value of the OperationTimeoutSec parameter are not recoverable, because the operation on the server times out before the client can reconnect.
 
.OUTPUTS
 
Microsoft.Management.Infrastructure.CimInstance#root/cimv2/Win32_ShortcutFile
 
.NOTES
 
If a shortcut is present in the start menu, an instance of a Win32_ShortcutFile is returned that has a Target property.
