LicenseCrawler 原文簡介：
If you want to setup your computer system again you need to have the licenses and 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 every other application.
Instead of searching for the keys in your e-mails, manuals and recipes you could use another approach. LicenseCrawler is a sweet little application that scans the Windows Registry for Windows product keys and other serial numbers and licenses.
The software can discover application product keys and other serial numbers or licenses very quickly and supports all versions of Windows operating system from Windows 95 to Windows 8.
The portable-version can be run from any location and would be a perfect fit for a USB stick. The software is ideal to backup your system, help IT-Service members and for forensic services.
