    Hi Zachary!

    You have an awesome Blog!

    The WMI/CIM Win32_Product class is considered evil!

    It is not recomende to use WMi/CIM and the class Win32_Product for this task!
    Unfortunately, Win32_Product uses a provider DLL that validates the consistency of every installed MSI package on the computer.
    If a Software installation is inconsistent the Sofware starts to try to repair themself with a reinstallation!
    That makes it very, very slow and in case of a inconsistent Software the task will hang!

    I have developed a Get-Software function which take use of the registry “uninstall” key instead.
