Microsoft Now Releasing Windows 10 Preview Update KB4586853 to Everyone

Like every year, the Windows team will take a Christmas break during which only a limited team will continue to work. Therefore, everything is a bit out of the ordinary at the moment. For example, there is now a new preview update for the May 2020 update for Windows 10 alias version 2004 and for the October 2020 update for alias version 20H2. Normally, these critical updates would have appeared sooner, except as there was a so-called out-of-band update on November 19th, Microsoft took a little longer with the next release. Users of versions 2004 and 20H2 will now receive update KB4586853. It increases the build number to 19041.662 and 19042.662 respectively. The update affects Windows 10 versions 2004 and 20H2 in all editions as well as Windows Server variants. The update is available through the Windows Update feature and in the Microsoft Update Catalog. The KB4586864 servicing stack update is mentioned as a prerequisite for the new release.
