DO AS WE SAY!!!!!! LOGIN WITH A WINDOWS ACCOUNT !!!
Because even though we are not being FORCED to use the MIcrosoft or Ofice 365 Accounts to log in its what Microsoft WANT people to do so they will Hide and make it hard to log in as a local account. that way Joe Public will just do it.
You need a Windows or Office 365 account to access Onedrive, App Store and other Microsoft services so why would they want people only using a local account as that does not potentially provide them with more revenue, ............................................ or allow their Overlords the NSA access to your data.....
