--wmi requires admin to work

[juliourena]

WMI queries can be enabled to any users, there are scenarios where an admin may want to provide such privileges to a non-administrator user. For example: https://serverfault.com/questions/28520/which-permissions-rights-does-a-user-need-to-have-wmi-access-on-remote-machines

If we remove the require admin, this is the result for a user with privileges and another user without privileges:
