NAME
    Win32::WindowsUpdate - Access to Windows Update functions

DESCRIPTION
    Currently only provides the ability to see installed and available not
    installed Windows Updates.

    The intention is to provide the ability to manage all features related
    to Windows Updates, including downloading, installing, uninstalling
    (maybe), and configuring Windows Updates.

    If you test this, please let me know your results. It's not ready for
    production use, but any testing is greatly appreciated.

EXAMPLE
      use Win32::WindowsUpdate;
      my $wu = Win32::WindowsUpdate->new;

      die "Reboot first...\n" if $wu->rebootRequired;

      my @updates;
      foreach my $update ($wu->updates)
      {
        next unless ($update->{Title} =~ m/Security Update.*Windows XP/i); # filter for something
        push(@updates, $update); # push it into the updates list
      }

      sleep 1 while ($wu->installerBusy); # if Windows Installer is busy
      die "Reboot first...\n" if $wu->rebootRequired; # if whatever WI finished doing requires reboot
      $wu->install(@updates); # install your selected updates
      print "Installed updates want you to reboot...\n" if $wu->rebootRequired;

METHODS
  new
      my $wu = Win32::WindowsUpdate->new;
      my $wu = Win32::WindowsUpdate->new({online => 0});

    Creates the WindowsUpdate object.

    online
        Defaults to 1. Check online for updates.

  updates
      my $updates = $wu->updates;
      # .. or ..
      my @updates = $wu->updates;

      my $updatesHidden = $wu->updates({IsHidden => 1});

    Returns a list of updates available for download and install.

    IsInstalled
        Returns installed (if true) or not installed (if false) updates.
        Defaults to 0.

    IsHidden
        Returns hidden (if true) or not hidden (if false) updates. Defaults
        to 0.

  installed
      my $installed = $wu->installed;
      # .. or ..
      my @installed = $wu->installed;

    Returns a list of installed updates.

  install
      my @updates;
      foreach my $update ($wu->updates)
      {
        printf("Available Update: %s %s\n", $update->{UpdateId}, $update->{Title});
        next unless ($update->{Title} =~ m/Security Update.*Windows XP/i);
        printf("Want to install: %s\n", $update->{Title});

        push(@updates, $update->{UpdateId});
        # .. or .. (both ways will work)
        push(@updates, $update);
      }

      $wu->install(@updates);

    Install specified updates. Provide an array of either "update" (directly
    from "$wu->updates") or "updateId". See example above for usage.

    Currently implemented via VBScript (via Inline::WSC). Perl code exists
    in the module to do it without VBScript, but it doesn't work. If you
    would like to help, please check out the source of this module to see
    what's going on there.

  rebootRequired
      my $needToReboot = $wu->rebootRequired();

    Returns bool. True if reboot is required, false otherwise.

    You should check this before and after you run "install". If it's true
    before you install, you'll want to reboot before you install. If it's
    true after you install, you'll want to reboot sometime.

  installerBusy
      my $installerIsBusy = $wu->installerBusy();

    Returns bool. True if Windows Installer is busy, false otherwise.

    If the installer is busy, you probably won't have any success at running
    "install". You could just sit in a loop waiting for it to no longer be
    busy, but you'd want to check "rebootRequired" immediately before you
    run "install" to be sure you won't want to reboot first.

TODO
    Provide ability to install specific updates.
    Determine other necessary features. (email me with your requests)
