Thank you for your question, this is a very important consideration! I am also about to migrate to Windows 10 and I was wondering about the same thing. I did a little research and I found out that Bruker QMatrix does not run without [DIA] Analysis Management and If we migrate QMatrix to Windows 10 or have to reinstall it, our already installed [DIA] version will not work. I also found out that the German company for software development Fink & Partner GmbH is the official developer, vendor, and supplier of [DIA] Analysis Management, and that they are not delivering [DIA] with Bruker anymore.
There is also an official press release published on February, 1st 2021.
