"None" is a default builtin group in the local SAM of all Windows NT
versions since the beginnings.  All local user accounts, including the
admin account, have their primary group set to "None".  This is a fixed
setting which cannot be changed.  Primary group membership can only be
changed for domain accounts.

The name "None" is actually localized, it's only "None" for the english
Windows versions.  It has always the SID combined of the computer SID
with an attached RID of 513.
