This one line command will zero out all of your Windows event logs – over time these can grow to considerable size. In most environments the default logs are set to roll at a certain file size….on my client machines there is seldom a use for poking around these logs and should be clearly out regularly.

For clients with centralized logging / machines not subject to audit (or not!) I suggest running this on shutdown via group policy.
