Prevent is a little application for the Windows operating system that will block basic file operations while running. This can be useful for users who want to prevent that other users access and manipulate files on their computer system while they are away. This might not always be the perfect solution though, as many users prefer to lock the computer system instead to prevent unauthorized access. Prevent however might make sense where access is allowed to the computer system, e.g. on a family computer.

Prevent will block the following operations while running on a computer system:

  • Stops Cut
  • Stops Paste
  • Stops Copy
  • Stops Delete
  • Stops Copy To
  • Stops Move to
  • Stops Send To
  • Prevents renaming
  • Disables Task Manager’s End Process button.

Users who work with the computer system while Prevent is running will not be able to copy and paste information or copy, delete, rename or move files on the system. A hotkey is available to stop the Prevent program from running so that the operations become available again. The system is obviously not fool proof. It is for example possible to use another program like Process Explorer to kill the process.

Prevent is available at the Windows Club website.

When it comes to the shortcuts, you need to know them to make sure you can stop the program. The latest version of Prevent lets you change the hotkey, so that you can change it to whatever key combination you would like. Plus, it supports two hard coded kill switches that let you kill the processes of the program even if you can't remember the original hotkey. You can kill the processes with the hotkeys Windows-F8, and Windows-F9.

      That’s because of the functionality of the program, not because it is a virus or trojan
