#Or for the File to be Placed in the Current Directory
Start-Transcript "MyTranscript.txt"
#Or for the Default Location (..\Do C:\Users\userID\Documents\PowerShell_transcript.NNNNN.txt

#To Stop the Transcript from Recording Commands and Output

#Set the Script Execution Policy for Current User 
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

#Get All Currently Loaded PowerShell Snapins

#Get All Commands in a Specific PowerShell Snapin
Get-Command -pssnapin NameOfPSSnapin #(e.g. Microsoft.PowerShell.Security)

#Get All PowerShell Modules Available on System
Get-Module -ListAvailable

#Import Module in Current PowerShell Session
