Every time you delete a file, Windows Vista asks you "Are you sure you want to move this file to the Recycle Bin?"
This is typically a good thing, to prevent you from deleting files by accident, but if you are trying to do some cleanup and need to delete a lot of files, you might not want to be prompted every single time. In addition, when you empty the recycle bin, still there is a confirmation dialog . So i think there is no need to confirm twice.
There's a simple way to turn it off, thankfully, although I'd recommend you leave it on the majority of the time.
Just right-click on your Recycle Bin and choose Properties from the menu.

Now you'll see the Trash Properties dialog, and notice the "Display delete confirmation dialog" at the bottom.
Just uncheck the box, and close the dialog. No more confirmations! (I'd still recommend that you turn it back on when you are done cleaning up your computer)
Besides, there is another way to make this. Just press the Shift key while deleting (either with Delete key or mouse) and it will bypass the Recycle Bin all together. However, this is only when you really know that you won't need to recover the file from Recycle Bin .
