.SYNOPSIS
    Collects data on system and network configuration for diagnosing Microsoft Networking.

.DESCRIPTION
    Collects comprehensive configuration data to aid in troubleshooting Microsoft Network issues.
    Data is collected from the following sources:
        - Get-NetView metadata (path, args, etc.)
        - Environment (OS, hardware, domain, hostname, etc.)
        - Physical, virtual, Container, NICs
        - Network Configuration, IP Addresses, MAC Addresses, Neighbors, Routes
        - Physical Switch configuration, QOS polices
        - Virtual Machine configuration
        - Virtual Switches, Bridges, NATs
        - Device Drivers
        - Performance Counters
        - Logs, Traces, etc.
        - System and Application Events

    The data is collected in a folder on the Desktop (by default), which is zipped on completion.
    Use Feedback hub to submit a new feedback. Select one of these Categories:
        Network and Internet -> Virtual Networking
        Network and Internet -> Connecting to an Ethernet Network.
    Attach the Zip file to the feedback and submit.

    Do not share the zip file over email or other file sharing tools. Only submit the file through the feedback hub.

    The output is most easily viewed with Visual Studio Code or similar editor with a navigation panel.

.PARAMETER OutputDirectory
    Optional path to the directory where the output should be saved. Can be either a relative or an absolute path.
    If unspecified, the current user's Desktop will be used by default.

.PARAMETER ExtraCommands
    Optional list of additional commands, given as ScriptBlocks. Their output is saved to the CustomModule directory,
    which can be accessed by using "$CustomModule" as a placeholder. For example, {Copy-Item .\MyFile.txt $CustomModule}
    copies "MyFile.txt" to "CustomModule\MyFile.txt".

.PARAMETER MaxThreads
    Maximum number of simultaneous background tasks, from 1 to 16. Defaults to 5.

.PARAMETER SkipAdminCheck
    If present, the check for administrator privileges will be skipped. Note that less data
    will be collected and the results may be of limited or no use.

.EXAMPLE
    Get-NetView -OutputDirectory ".\"
    Runs Get-NetView and outputs to the current working directory.

.EXAMPLE
    Get-NetView -SkipAdminCheck
    Runs Get-NetView without verifying administrator privileges and outputs to the Desktop.
