Microsoft Visual C++ Redistributable Packages are required public DLL runtime libraries for any software written using Microsoft Visual Studio 20XX IDE, which can be interpreted as the dictionary files for running programs. And considering the application's file size, most of them do not come with those common DLL files. As a consequence, installing the corresponding runtime libraries are always the first thing to do before using this kind of applications.

In some conditions, we need/want to close the monitor's power immediately (lowering the screen's brightness is meaningless), rather than waiting for the computer to enter its power saving mode and then do this for you. Note that, empty or pure black screen saver can not achieve this effect, because any screensaver obviously becomes very bright in dark environments.

DriverFinder is a very simple, lightweight but powerful hardware driver manager. It can help you fast scan and identify those expired, inaccurate or unrecognized/unknown devices' drivers with ease. And it provides quick drivers download & automatic installation/update. Again, in DriverFinder, you're also allowed to manage (backup/restore) all drivers installed in your computer in batch.

If someone says you want to use this kind of tool to verify the security of passwords or recover them, that would be a joke, I think. After all, a rule for secure enough password is very simple - Uppercase + Lowercase + Number+ Symbol (and > 8 characters), there is no need of any tool to validate it at all. The same for wireless network password, restoring it is meaningless - just reset the router to default, which is the most efficient way. So, obviously they are designed for passwords cracking only.

On many users' computer, it's probably that an EPUB (mobile-specific ebook format) reader is not installed at all. In that case, what we first think of is to convert it to the most commonly used and universal format for almost any device - PDF, therefore we still need some tool to help.
