Upon setting up a new computer with Windows 10 (with Cortana) the user account created in the initial set up issues a “can’t sign into your account” notification once set up is complete and user is signed in. In addition, default apps seem to be missing, and MS office apps to not function properly. I was able to resolve the issue with windows command prompt by manually creating another admin user. Once signed into that account, I was able to access all default apps and had no notifications or other issues with MS apps. I am wondering why this issue is happening? I have had several computers that have done this that were brand new.
