Re: Question about SC 1.4.2 - can this be met by relying on Windows (or otherwise the platform or user agent) to do it for you?

Yes that would be a technique if you are in an environment that guarantees that only Windows 7 (or whatever versions) are used by people viewing the web page.   Not sure how you would enforce that.  Otherwise it would not work.

  So we couldn’t list it as a sufficient tech I wouldn’t think.
