DeskLock is a simple and portable tool for locking desktop icons in place.

It resides in the systray and prevents the moving of desktop icons when active. It supports double-clicking of the tray icon to disable/enable, and there is also the option to disable left drag and right mouse buttons.

DeskLock can also show the class of items, and a hotkey can be set allowing you to disable the app quickly when not required. Another straightforward little tool that serves a specific purpose and has minimal resource impact while in use.
