ProduKey for Windows download

Quick summary of ProduKey

ProduKey is a small, free utility from NirSoft that quickly reveals the registration details for Microsoft products installed on a PC. It locates and displays Product IDs and CD-Keys for Windows, Microsoft Office, Exchange Server, and SQL Server. The program is lightweight, fast, and intended for straightforward recovery of lost or forgotten product keys.

Main functionality

ProduKey's core purpose is to scan the system and present product identification and licensing information. Key capabilities include:

Showing the product key and associated Product ID for supported Microsoft products
Scanning automatically and listing results within seconds
Providing a simple, uncluttered interface for rapid access

What appears in the results

When ProduKey lists an entry, the main window includes several important fields so you can identify each license quickly:

Modified date for the entry
Installation folder path
Service pack or update level
Machine or computer name
The CD-Key value
Product ID string
Product or application name

Options and additional key types

An Options (or Settings) menu lets you broaden what ProduKey displays and where it searches. You can enable or extract keys for:

Microsoft Office and other Office-related products
Exchange Server and SQL Server
Windows editions and their keys
Internet Explorer-related keys

Where ProduKey can read keys from

ProduKey supports loading license data from multiple sources beyond the local running system:

A specified IP address range on the network
An external Windows directory or a Software registry hive file
All machines within a given domain or local network
A remote or local computer you specify

Note: Separate downloads are available for 32-bit (x86) and 64-bit (x64) systems; choose the build that matches the target OS.

Usability and when it helps

The interface is intentionally minimal so recovering a product key is fast and uncomplicated. If you need to reinstall software but have misplaced the original key, ProduKey provides a quick way to retrieve that information and continue with reinstallation or record-keeping.
