Product Key Explorer

Product Key Explorer is a very handy software solution that can scan your computer and retrieve product keys for installed applications.
The program relies on a very clean interface, with a well-organized list that displays the product name, data info and product data straight in the main window.
Product Key Explorer can search for serial keys for basically any piece of software that's installed on your system, including Windows and Microsoft Office. The scanning process takes just a few seconds and the application provides multiple tools to help you manage the product keys in a comfortable manner.
You can always back them up to a registry file format (reg), but also save them separately as Tab Delimited Txt File (.txt), CSV Comma Delimited (.csv), Excel Workbook (.xls), Access Database (.mdb), Web Page (.html) or XML data (.xml).
Another very interesting feature is the possibility to scan an IP range or an IP address list and extract the product keys, but remember that you need administrator privileges to be able to view the data.
Checking an entire network can take up to several hours, depending on the number of clients, but Product Key Explorer doesn't stress up the computer too much and remains light on resources.
A help file is always there to help you, with tons of information regarding every single feature that's included in the app.
So as a conclusion, Product Key Explorer is quite an effective way to deal with lost or forgotten serial keys. It's easy to use and it takes just a few seconds to reveal the information.
