ProduKey is a very simple software solution designed to show the product keys for the applications installed on your computer.

With a very simple and clean interface, ProduKey serves its purpose pretty well, coming with separate builds for both x86 and x64 operating systems.

The application works very fast and automatically scans the installed apps when you launch it, with all entries and the associated product keys displayed in just a few seconds.

The main window hosts all the necessary details for every single application, including product name, product ID, product key, installation folder, service pack, computer name and modified date.

ProduKey supports multiple sources to read the product keys, so you can set up the application to load the information from your local computer, from external Windows directory, from external Software Registry hive, from remote computer, from all computers in a specified domain, from all computers in the local network or from all computers in the specified IP addresses range.

Additionally, there's a separate “Options” menu to let the app extract Windows Edition and show Windows keys, Office keys, Internet Explorer keys, SQL Server keys and Exchange Server keys.

Obviously, since it's designed to perform such a simple task, ProduKey remains very friendly with computer resources and works with all Windows versions currently on the market.
