License Crawler is a free portable program for Microsoft Windows that scans the system for product and license keys to display them in its interface.

If you want to setup your computer system anew, you need to have the licenses an serial numbers at hand for all the software programs that you have purchased and registered. This does include the Windows product key but also other serial numbers for applications like Nero, Office, VMWare and pretty much any other application or game that comes with a product key.

Instead of searching for the keys in your emails, software boxes, CDs and DVDs, and receipts, you could use another approach. License Crawler is a sweet little application that scans the Windows Registry for Windows product keys and other serial numbers and licenses.

License Crawler

If you want to find the license or find the serial number for a product that you have installed on your system, then License Crawler may be your best bet. It is also the optimal solution before installing software on a system.

Say you use Nero regularly and it is causing problems lately. Before uninstalling and re-installing Nero, you may run License Crawler to find the serial of Nero and write it down.

The advantage of License Crawler is that it supports a wide range of products, especially when compared to other products that can only reveal Windows product keys. As long as the software stores its license key in the Registry it will be discovered by the software program.

License Crawler is compatible with most versions of Windows starting with Windows 95 up to the most recent versions of the Windows operating system. It is a portable application that can be run from any location and would be a perfect fit for an USB stick: Thinking tech support here asking clients to find the serial or license key; something that could end up in frustration. Starting License Crawler instead could reveal it without having to interact with the client at all.

The terms of use have to be accepted in the beginning. A click on the Start Search button crawls the Windows Registry trying to find serial and license codes. It is possible to change the Registry Hive or search them all but the best results are usually achieved with the default settings.

Update: The program has been updated several times since our initial review. It supports scans of other computer systems connected to the same computer network in its latest release, and comes with options to batch process data, and a tools section to encode or decode information, or to fill the whitelist or blacklist.

    Not sure if you’re still monitoring this board but i am running this software and it has been a couple hours running and not stopped yet. Do I stop it? So far, it has 12 keys (been 12 for past 1.5 hours); 12-15 entries (keeps changing); 125,142+ analyses data. I selected the default settings (Localhost, HKEY_ALL, 64bit scan, file based liscenses). When does this stop?

    Jaz companies like Dell usually use those keys, you should use the one on the sticker when reinstalling because that’s the one registered to you.

    Oh right, I have a Dell one. Would the key found by this program work when reinstalling?

      Thank you very much,it’s very useful!
      Once, I paid two times for the Vista product key because I forgot the product key at the first time then, I had no choice but bought it again. It not only waste money but also wastes time. Then I tried a software called Password Genius. It can find windows product key only within 1 minute. Hope this can help you !
