MessageBox Maker

MessageBox Maker lets you create popup messages with any text you want and display them on Windows startup.

You'll have a wide array of options at your disposal to configure your message. First, as usual, you have to write the title and body of the message. That done, you'll choose the icon you want to see in the message window (error, question, warning, notification...) and the buttons with possible answers (OK, OK and cancel, Yes and No, etc.).

Once you've configured all the details, you just have to hit the 'Launch' button and wait for the next startup so you can view your message.

MessageBox Maker is a very useful program for people who share a computer with multiple user accounts, since it lets you notify the next user of any ongoing issue with the computer.
