Living proof that no matter how much you use Windows on a daily basis, there's always something somewhere you find which strikes you as "wow, never knew that". Although I have a custom performance monitor MMC snap-in at home, for example, for monitoring network throughput on my broadband connection through my ISA Server, I never realised you could use options on the menu bar to change the task managers network tab view to show bytes sent and bytes received in red and yellow respectively. Obviously it's not as accurate or flexible as the performance monitor, it's still useful to know. The option's on the View menu under Network Adapter History.
