.SYNOPSIS  
    Sets whether the product representing the category of updates to synchronize is enabled or disabled.
    
.DESCRIPTION
    The Set-PSWSUSProduct cmdlet enables or disables the product representing the category of updates to synchronized.
    In order to use this cmdlet, the Get-PSWSUSUpdateCategory cmdlet must be run (optionally using the Where-Object cmdlet to
    filter its results) with its results piped into this cmdlet.
    
.PARAMETER Product
    Specifies the product for which the updates are to be synchronized. If the Disable parameter is used, then this parameter
    specifies the product for which the updates are not to be synchronized. This parameter value is piped from the Get-PSWSUSUpdateCategory cmdlet.
    
.PARAMETER Disable
    Specifies that updates are not to be synchronized for the specified product.
