Windows Reversible Encryption

Ok, So I've did the following in order to reduce the strength of my Windows XP Pro password.

1-Run > secpol.msc

2-Security Settings > Account Policies > Password Policy

3-Store password using reversible encryption for all users in the domain:Enable

My question is How do I go about reversing my password. After googling this, I've discovered is that this basically stores the password in plain text, but I still don't understand how I would be able to view my password. I have restarted my computer. I've even dumped my passwords using fgdump, but they extracted the usual hashes. Any help is be appreciated.

I tried researching this as well and found that Microsoft does not publicly document either the encryption used or the instances in which it is used in his encrypted or unencrypted forms. You'll find speculation on some sites, though, so those might give you some clues on what to attempt or leads on more information. If you do actually find anything of worth, you should write an article.
