.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.)

    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 BackgroundThreads
    Maximum number of background tasks, from 0 - 16. Defaults to 5.

.PARAMETER Timeout
    Amount of time, in minutes, to wait for all commands to complete. Note that total runtime may be greater due to
    post-processing. Defaults to 120 minutes.

.PARAMETER ExecutionRate
    Relative rate at which commands are executed, with 1 being normal speed. Reduce to slow down execution and spread
    CPU usage over time. Useful on live or production systems to avoid disruption.

    NOTE: This will force BackgroundThreads = 0.

.PARAMETER SkipAdminCheck
    If present, skip the check for admin privileges before execution. Note that without admin privileges, the scope and
    usefulness of the collected data is limited.

.PARAMETER SkipLogs
    If present, skip the EVT and WER logs gather phases.

.PARAMETER SkipNetsh
    If present, skip all Netsh commands.

.PARAMETER SkipNetshTrace
    If present, skip the Netsh Trace data gather phase.

.PARAMETER SkipCounters
    If present, skip the Windows Performance Counters collection phase.

.PARAMETER SkipWindowsRegistry
    If present, skip exporting Windows Registry keys.

.PARAMETER SkipVm
    If present, skip the Virtual Machine (VM) data gather phases.

    Get-NetView -OutputDirectory ".\"
