.SYNOPSIS

      Queryies a computer by its computer name using CIM for basic information about the computer specified.

.DESCRIPTION

     The Get-ComputerInfo.ps1 script uses CIM to get information about a computer that is specified in the -ComputerName parameter.

     The -ComputerName is optional, when not specified, the script defaults to the name of the local computer for the input to the -ComputerName parameter. This script gathers information such as BIOS, Disk, Memory and other specific information about the computer.

.EXAMPLE

     Get-ComputerInfo.ps1 -ComputerName <String>

     This command uses the name of computer as input and returns information about said computer.

.EXAMPLE

     Get-ComputerInfo.ps1

     This command is being ran without the -ComputerName parameter and the user will be prompt for the computer name during the script execution.

.EXAMPLE

     Get-ComputerInfo.ps1 -ComputerName <String> | Out-File -Append <String>

     This command uses the name of the computer as input, and then writes the output of the script to a file defined in the command.

.NOTES

     Some things such as sorting output, formating output, and selecting output that is generated from this script does not work at this time. Also this script works best in domain enviroments, where one is querying another computer on a domain using its computer name.

     This script also has been tested over a VPN and it works if your VPN is set up correctly.

     The operating systems that this script has been tested on includes but is not limited to is Windows 10, Windows Server 2016 Datacenter, and Windows Server 2019 Datacenter.

     Note about current logged on user value: when no user is currently logged on the system, the value will be null.
