Where can I find the list of approved/supported Windows Security Updates now? The website seems to have changed (again). It used to be http://www.virtuozzo.com/products/virtuozzo/updates/, as shown in the Additional Info section of https://kb.virtuozzo.com/985. The only thing I could find is KB3140410 being supported after installing this months VZU460103: https://kb.virtuozzo.com/en/128541. But typically there are other KB's that don't need these VZU's and can be safely installed. The whole list used to be in before mentioned URL.
