Server Operators is a group of limited usefulness. It only exists on domain controllers, and only enables a member to perform a small number of specific functions. Installing updates requires Administrator permission to a much wider scope of the file system and registry, and elevated privileges.
Additionally, Server Operators is a 'protected group'. Windows further restricts access to the members of protected groups, which can lead to unusual and difficult to solve permissions, delegation, and inheritance issues. I would discourage using Server Operators, Account Operators, or Backup Operators.
