Changes

 * As of 2021, it is the earliest available build to drop the Windows Server 2012/2012 R2/2016/2019/2022 flag and replace it with the new, flat one, although some resources still use the old flag.
 * Newly added log drives will be formatted with no file system (RAW drive).
 * SMB compression has now been enabled by default.
