Designed and developed by TeknoPartner, AppLock, as its name suggests, is intended to help users implement full control of all the applications in their systems. This utility is available on a free to try basis, with certain functional limitations. Using this software application, you will be able to assign passwords to restrict access to applications, lock as well as unlock various programs in your system, and also enable or disable Windows Task Manager. In other words, you will be able to control the appearance of this window by restricting the usage of “Ctrl” + “Alt” + “Del” keys. You can also use this tool to restrict the use of Regedit, the Registry Editor of your Windows system.
