Free Download Manager, one of the best free download manager

One of the best free download manager at this time (meaning a download manager that install spyware or other junk on your computer), among other things also become open source, which is worth further from my point of preference. It has many useful functions, including that automatically divide a file into pieces to speed up the download, a nice graphical interface, resume broken downloads, and support fully automated major browsers including Explorer, Firefox and Opera.
For a second configuration may confuse, but actually just download something to see how everything is simple and straightforward: you realize how it works immediately without touching almost nothing.

License Crawler, Recover password

If we have to reinstall the operating system application software (or switch to a newer operating system), there will surely codes and licensing of any paid programs we installed.
To do so, or we look for manuals, email account, floppy disks, which are marked on these license codes, or use a program that can automatically search on our computer, and save a plain text file (so that can copy and paste the new system).
The program does for us is therefore License Crawler, lightweight (about 70 kb), portable and fully automatically. Just click Start Search, and will act alone, through a scan of our record, check the serial numbers of installed programs. Then simply select SAVE from the menu and store them in a text file.
Is usually able to find some serial more than the competitor SoftKey Revealer.

SoftKey Revealer and GameKey Revealer

There are two simple programs that deal with password recovery applications and games (if GameKey Revealer) that are installed on our system. The password recovery can then be exported in a single Word document.
SoftKey Revealer GameKey and thus become useful when you must change your computer (or just reinstall the operating system), because we all passwords recovery and serial numbers of our programs and our games.
Both are portable (no installation required). If SoftKey Revealer was not able to find some program, I suggest the alternative License Crawler.

Cain & Abel, complex password recovery

It a very advanced program in English and complex password recovery (especially on different networks or connections, but also for those covered by asterisks in our computers) very powerful. The use is not the most immediate, because the large number of menus and options (for every type of password management is a different function).
Findings difficult ... Cain and Abel on the one hand is very powerful (I would say exceptional), and certain things did not equal even the best paid programs (especially when it comes to networks or connections), second in some cases is quite complex to retrieve old forgotten passwords, and it is not immediately (you must dedicate time to understand). Very often, before giving up to find a password, you must stop and study the program, because you have not used the right function.
In other words, a program of great value, but not (too) suitable for the average user.
NOTE: Some antivirus report as computer virus. Obviously not a computer virus, is a program that can recover all types of passwords. If you use it on your computer is perfectly legitimate, if they use others without your knowledge ... here is the antivirus I'll report ...
