Win 2004 Window Color BUG
Since the recent windows 2004 release the windowcolor is white instead of the previous grey.
We are delighted to share with you that Acrobat and Reader Desktop release for DC Continuous (20.012.20041) is Live now and this takes care of this issue.

Please update your Acrobat/Reader (It should Auto update or you should do Help → Check for updates) and let us know your Feedback.
