Of course you can use shortcut key ‘Alt + Left Shift + NumLock’ to enable Windows own utility for moving cursor, but it is not smooth like this tool.
With this utility you can speedup the cursor move by choosing 1px, 2px or 5px and pushing 'M' will allow you to toggle virtual mouse clicking. Pushing NUMLOCK will give you the current coordinates of the current cursor positions.
CursorMover works with Windows7, Vista and XP. Download CursorMover
