Let's face it, keeping track of all your purchased software's keys, codes and licenses can be a pain. These long and random set of characters can be printed on a sticker label, an old software CD case or stashed in an email somewhere.

Simply put, if you don't keep a record of all these keys, they can be all over the place.

Not having these activation keys can be a huge problem if you have to set up your computer again. You'll have to reinstall and reactivate all your purchased software with these codes and depending on how well you have secured them, you might have to search and rummage through your emails, documents, cd cases and manuals just to find them.

In this modern age of digital conveniences, keeping a record of all your keys shouldn't be that hard, right?

Well, you can save and keep a text document of all your keys or you can try this - a free program that's aptly named LicenseCrawler.

You don't even have to enter your activation keys one by one. LicenseCrawler scans your PC's Windows Registry product keys and other serial numbers and licenses and automatically saves them.

You can then install the portable version of LicenseCrawler on a USB stick to backup your keys and restore them when the need arises. That will definitely be a time-saver if you ask me!

Note: LicenseCrawler supports all versions of Windows, even Windows 10. And, although it works with most programs, it can't store Windows product keys.

How to download and install

To download LicenseCrawler click on the blue download link below and this will take you to the LicenseCrawler download page. Scroll down and click on any download mirror link under the "Portable-Version available at following sites" section.

Next, extract the contents of the downloaded zip file and this will create a LicenseCrawler folder. Click on the LicenseCrawler.exe to start the program.

Note: If you are getting this error "Run-Time error '339': Component 'mscomctl.ocx' or one of its dependencies not correctly registered: a file is missing or invalid," try again by right-clicking on LicenseCrawler.exe then choose "Run As Administrator."


To start the license key scan just follow the initial prompts then specify the target computer (in most cases, just leave it on "localhost" and "HKEY_ALL") then click search.

Note: Although LicenseCrawler is free for private use, the unregistered version may display ads for other software,  just wait for the ad preset timer to expire to proceed. To register the software, visit its license information page.
