Introduction
Nobody will likely dispute the fact that Internet Explorer is today's most popular Web browser. According to the statistics, approximately 70% of online users prefer to use just this program. Arguments about its pros and cons may last forever; still, this browser is the leader of its industry, and this is a fact that requires no proof. Internet Explorer carries several built-in technologies, designed to make average user's life easier. One of them - IntelliSense - is made for taking care of the routine tasks, like the automatic completion of visited webpage addresses, automatic filling of form fields, users' passwords, etc.
Many of today's websites require registration, which means, user would have to enter user name and password. If you use more than a dozen of such websites, you will likely need a password manager. All modern browsers have a built-in password manager in their arsenal, and Internet Explorer is not an odd. Indeed, why would one have to remember yet another password if it is going to be forgotten some time soon anyway? Much easier would be to have browser do the routine work of remembering and storing passwords for you. It's convenient and comfortable.
This would be a totally perfect solution; however, if your Windows operating system crashed or reinstalled not the way it's supposed to be reinstalled, you can easily lose the entire list of your precious passwords. That's the toll for the comfort and convenience. It's good just about every website has a saving 'I forgot password' button. However, this button will not always take your headache from you.
Each software developer solves the forgotten password recovery problem their own way. Some of them officially recommend copying a couple of important files to another folder, while other send all registered users a special utility that allows managing the migration of private data, and the third ones pretend they are not seeing the problem. Nevertheless, the demand creates the offer, and password recovery programs are currently on a great demand.
In this article, let's try to classify types of private data stored in Internet Explorer, look at programs for the recovery of the data, and study real-life examples of recovering lost Internet passwords.
