Tell When Done is an interesting tool which can monitor a program and tell you when it's finished processing (sometimes, anyway).

Imagine you have some program which you know will be running for a while, for instance, but won't raise an alert when it's done. Normally you'd have to keep manually switching back to the window to see how it's doing: very irritating.

With Tell When Done, though, all you have to do is start the program running (making sure it's the foreground window), and press the Tell When Done hotkey (Windows key + T). TWD will then monitor the process CPU usage, and when it's finished, will alert you with an audio signal and a pop-up window.

In simple situations this appears to work just fine, and the program properly alerted us on several occasions.

Sometimes, though, the program you're monitoring actually launches some other process to carry out the work. And we found this wasn't detected by Tell When Done, which just told us immediately that our program had finished when this wasn't true at all.

Tell When Done isn't sophisticated enough to be useful all the time, then, but it's worth trying anyway just to see how the program works for you.
