What uses the WDAGUtilityAccount local account on Windows 10. Detail: Sometime within the last 18 months the WDAGUtilityAccount local account was added. The account is disabled and doesn't appear to be in any account groups such as local admins or users. I haven't checked which windows user account rights that it has. The only legitimate reason that I can think of for adding, without me knowing about it, would be during a windows update was applied. ........................ I would not known about the account if I hadn't been using 'computer management --> 'users and groups'
