This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
It autodetects Windows NT, but that really isn't specific enough. I am going to file a bug about font rendering on the WebPlatform.org project, and Windows' font rendering can be vastly different from version to version.
It's a bit silent here, this bug is 1+ years old. While I can live with Windows NT and make more specific in the text of the bug report, it's better if it gets updated to allow better browsing and searching.
