How to Get Back the Product Keys You Lost In a Computer Crash

Product keys are like bank accounts. They should be kept somewhere safe. A Windows crash is misery enough without the hair-splitting if you happen to lose your product keys. Product keys are imprinted on the package your installation disks came in. Keep them safe and backed up is the first advice. Know how to retrieve them if you have been lazy is the second.

ProduKey is one of those neat little system tools that you wouldn’t notice unless the catastrophe of losing your product keys hits you. If you want to reinstall your Microsoft Office (Microsoft Office 2003, Microsoft Office 2007), Windows (Including Windows 7 and Windows Vista), Exchange Server, or SQL Server on your computer, this small utility comes to the rescue by helping to retrieve the original product keys from the current Windows OS.

The download bundle is a tiny 47 KB ZIP file. Extract it to a folder. ProduKey is a standalone app and you can even run it from your Flash drive. Clicking on the EXE file launches the app and it immediately retrieves all the available product keys from the installed programs on your Windows system.


ProduKey can also recover product keys from a broken Windows installation copy. The following screen appears when you select File > Select Source. The utility can locate and recover product keys of connected computers, do it from an external disk, recover product keys from all connected computers in a network, and also do remote recovery if specified. The network feature makes it a powerful tiny backup app to have around to solve troubleshooting jobs.


You can save selected product keys in a text file and also generate a HTML file. Do you keep backup copies of your product keys? If not, then do you think ProduKey is a good fallback option to have around?
