HiddeX is a tiny desktop-enhancing program, developed by Igor Smorodsky from Russia. It's designed with the specific purpose of hiding currently active programs on a computer, without terminating their processes. It has the capability of making chosen programs vanish entirely from your screen, and can also conceal taskbar icons.

In order to prevent unauthorized people from opening some apps on our smartphone and exposing privacy, we can use the built-in or third-party app locking feature. On computer, we can use the professional AskAdmin or the more friendly Simple Run Blocker to block given programs from being run by others. For example: forbid children to open certain games or software.
