Deleting Locked Files (32 and 64-bit)

It seems like on Windows I always come across those pesky files I can't delete because another process is using it. Up until a few months ago I had always used a program called Unlocker to get around this, and it has served me well. I had to stop using it, however, when I moved to Vista 64-bit since it only includes support for 32-bit versions of Windows.
