    .SYNOPSIS
        Sets whether the product representing the category of updates to synchronize is enabled or disabled.
     
    .DESCRIPTION
        The Set-PoshWSUSProduct cmdlet enables or disables the product representing the category of updates to synchronized.

        filter its results) with its results piped into this cmdlet.
     
    .PARAMETER Product

        specifies the product for which the updates are not to be synchronized. This parameter value is piped from the Get-PoshWSUSUpdateCategory cmdlet.
     
    .PARAMETER Disable
        Specifies that updates are not to be synchronized for the specified product.
