I needed to go through a number of servers and check what hotfixes had been installed. I had a feeling Win32::TieRegistry could do that for me. The code needed to do so is surprisingly short.

It took me about 20 seconds to read the documentation and do the following. Bravo tye. My only gripe is that I typed in slashes rather than backslashes, and it didn't like that (although this was written on a 5.6.1 installation, for all I know this is fixed in more recent versions).

#! perl -w

use strict;
use Win32::TieRegistry;

use constant BASE => 'LMachine\\Software\\Microsoft\\Windows NT\\Curre
+ntVersion\\HotFix\\';

my $fix = $Registry->{+BASE} or die "oops, not admin? ($^E)\n";

foreach my $f( sort keys %$fix  ) {
    chop(my $id = $f);
    my $desc = $Registry->{BASE.$f}{Comments} || '<no description>';
    print "$id\t$desc\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
