I'm not good with computers. Have only NEN ragged laptop to browse. This can't use wlan anymore (diagnostic service is not used) which is why I searched the internet for solutions, where I'm on the command. Net localgroup administrators / add localservice came across. When running came, however, "the specified local group does not exist". What can I do?
Should reinstall Win 7. Will be easier for you. Maybe even upgrade to Win 10, should still go for free.
Groups are localized to Windows. If you have a German Windows, the group is most likely called "Administrators" and not "Administrators".
With "net loacalgroup" you can have a list of groups displayed.
