Hey! This is the old a broken mold. Newer stuff is at abrokenmold.net.
That being said, feel free to rummage through the archives over here. Also feel free to leave comments; we're still keeping an eye on this.

I actually had gotten the security tab via a shell extension a while ago, but it seemed to be the source of instability problems, so out it went. There are other ways to do it, but MS lets you have it for free with the Windows NT SP4 Security Configuration Manager. I haven't tried it out yet, but it sounds pretty sweet. Not that I really need it, but hey, it's power for nothing.

Here's the download page, here's the FTP folder it's in, and here is a direct link. If you check out the FTP folder, the file you want is SCESP4I.EXE.

Update, December 19, 2009: Having just had to install this due to a couple of folders on my external hard drive getting locked by my previous XP install, I can now recommend a specific install procedure. Run SCESP4I.EXE, select a folder in which to extract the files. Go to the folder, right-click setup.inf, click Install, and wait for the magic to happen. It will inform you, if I remember correctly, that you will need to restart your computer for the changes to take effect. That, fortunately, is not true. You can test this by right-clicking a file, going to Properties, and going to the Security tab. There it will be in all of its XP Pro glory. Enjoy.
