Avoid having to retype, scroll, or otherwise hunt for the WinDBG commands that you've executed in your current debug session!
Simply load the WinDBG Command History extension into your debug session and it will silently record every command that you execute. Once you're ready to use one or more of those commands again, execute the !cmdhistory command. You'll be presented with a DML hyperlinked list of every command that you've executed, providing convenient access to the commands that you've used in your debug session.
