Hi there,

For a project I need to track all installed third party software updates. All windows updates (KB....) can easily be obtained through CLI, not the third party updates.

Through scaning through registry with regedit I found that all patches can be found in values of HKEY_CLASSES_ROOT\Installer\Patches\xxxxxxxxx\SourceList (PackageName)

I can read all subkeys and values if I know the XXXXX values. But I don't, and I can't manage how.....

This code retrieved the values of a particular subfolder XXXXXXXXXXXXX:

use Win32::Registry;
$p = "Installer\\Patches\\18337E8B1B905984CA0D4383B5F025D6\\SourceList
+\\Media";
$main::HKEY_CLASSES_ROOT->Open($p, $CurrVer) ||  die "Open: $!";
$CurrVer->GetValues(\%vals); # get sub keys and value -hash ref
foreach $k (keys %vals) {
    $key = $vals{$k};
    print "$$key[0] = $$key[2]\n"; # see below for explanation
}

Win32::TieRegistry, the better version of Win32::Registry only gave undef values...... That seems to lie in 64 bits registry

Has somebody a clue how to get all XXXXXXXX values?
