Is there a reference to all Windows "errorlevel" by command?

"here http://wiki.fdosdotorg/Main/ExitCodes is an old list that covers many typical command line commands

here http://www.computerhope.com/doserror.htm is a list of the most typical error messages with an explanation

and here http://en.kioskea.net/faq/sujet-2347-error-codes-in-windows is a more complete list of windows error codes, some are surfaced as exit codes and some are not."

I'm finding that more and more applications use browsers as their user interface and I am caught in a dilemma.

Try Prism for Firefox or a Google Chrome application. I think these might deliver what you're looking for.
