点击图片放大Removable storage devices are an incredibly cheap and highly-efficient method of data transfer. This is both good and bad, because not only can you have documents wherever you are without the need of an active Internet connection, but classified documents can also be subject of theft. However, applications such as USB Port Locked promise to do exactly what the name suggests, offering that extra protection you need.
Easy to deploy on your system
With no installation required, the application comes in a pretty light package and can be safely stored on any device capable of storing a few MB. Neither is running it a complicated task, but doing so on the latest Windows versions requires administrator privileges.
Lets you quickly accommodate
Available features are stored in a compact window, with no unnecessary visual elements or anything to make it stand out in the crowd. Two buttons are dedicated to the main function allowing you to easily lock or unlock USB ports.
Leaving a little something to be desired
However, this step must only be done before anything is connected, otherwise nothing happens and full access is granted. What's more, the application was only capable of blocking storage devices from being used, other peripheral utilities still being usable, even if connected after restrictions were put into effect.
More tools to work with
The application also comes equipped with a few more tools found in a dedicated menu. All of them are plain and simple, bringing nothing more than what your operating system provides. You have an Autorun Killer, Task Manager, Calculator and File Explorer that only lets you run files, not even a basic context menu being included.
Far from being a pro
Furthermore, you cannot set the application to stay hidden in the system tray, leaving ports a little vulnerable. Moreover, there is no integrated option that lets you add it to startup items, so you have to run it every time you launch Windows.
In conclusion
To sum it up, USB Port Locked is a bit far from being a professional security application of its kind. Sure, its intentions are good and work properly, but the overall design feels a little rough around the edges and you don't really feel secure. With a little more work though, all of this can change.
可移动存储设备是数据传输的一个令人难以置信的廉价和高效的方法。这是有好有坏，因为你不仅可以拥有文件无论你在哪里没有激活的Internet连接的需要，但机密文件，也可以承受盗窃。然而，应用程序，如USB端口锁定的承诺，做的正是顾名思义，提供你需要额外的保护。
易于部署在系统上
无需任何安装，应用程序是在一个美丽的光包，可以安全地存储在能够存储几MB的任何设备。无论是运行一个复杂的任务，但在最新的Windows版本，这样做需要管理员权限。
让您快速适应
可用功能都存储在一个紧凑的窗口，没有不必要的视觉元素或任何使它脱颖而出在人群中。两个按钮都献给了主要的功能，让您可以轻松地锁定或解锁USB端口。
留下一点点不满意
然而，这一步必须只做过任何连接之前，否则什么也不会发生，并充分授予访问权限。更重要的是，该应用程序是唯一能够被使用，其他外设事业仍在使用的阻挡存储设备，即使连接后，限制被付诸实施。
更多的工具一起工作
该应用程序还配备了专用的菜单中多了一些工具。他们都是简单明了，带来无非就是你的操作系统提供。你有一个自动运行杀手，任务管理器，计算器和文件浏览器，只有让你运行的文件，被列入甚至没有基本的上下文菜单。
远不是一个亲
此外，您不能设置应用程序留下隐患在系统托盘中，让港口有点脆弱。此外，没有集成选项，可以让你将它添加到启动项，所以你必须每次启动Windows时运行它。
结论
概括起来，USB端口锁定是有点远不是同类专业的安全应用程序。当然，它的意图是好的，工作正常，但整体的设计感觉周围的边缘有点粗糙，你真的不觉得安全。随着更多一点的工作，虽然，这一切可以改变。
