Serial Key Manager

Serial Key Manager is a lightweight Windows tool designed to help you safely store all your serial keys, without the risk of losing them.
If you're afraid that such an application may be too difficult to use and you might encounter difficulties after launching it, well... that's not true.
Mostly because Serial Key Manager is so easy to use that everything comes down to just a few clicks, as you are prompted to write down the product name, the serial key, the key data and product information.
There are multiple options under the “File” menu, such as the dedicated tools to import or export key databases and remove specific or all entries.
Of course, you can also create, change and remove passwords, but there's one important issue to be clarified. Serial Key Manager saves all serial keys in the Windows Registry, which means they are safely stored in your computer.
There is no help file included in the application and the 'How to use” option in the “Help” section directs the user to an unavailable website, so Serial Key Manager doesn't provide assistance in case you get yourself into trouble.
On the good side, Serial Key Manager works well on most Windows version with the exception of Windows 7 where the program crashes every once in a while all of a sudden.
Overall however, if you're not looking for top-notch security features, Serial Key Manager is the right application to store your serial keys, as it provides basic features and a very easy to use interface.
