If you like to play jokes on friends, we offer you MBox, a program capable of baffling the most innocent, respecting the integrity of the equipment at all times.
The purpose of MBox is to generate error messages (the always feared Windows messages). To do this, you will have the possibility to create the message yourself, choosing the title, the text, the commands and the icon that is next to the text (with the game facing the "cachondeito" that this can give). The result of your error message will be saved as an executable file (EXE) and it is necessary to run it later in the Windows start menu of the victim's computer. When your friend starts it, it will take a big surprise.
Have a good time with MBox, and be very careful, because after using it, your classmates will want to take revenge.
You can free download MBox 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
