A really odd thing has happened to me during the upgrade process. My prior Windows login was simply Administrator and when I opened the VM it would just open into Windows with a user name and password combo being required. After upgrading to Win10 from P11, now it says I cannot sign in as Administrator (saying my account is disabled and does not show up as a user in the Win10 settings) and the only sign in available is now my name, which previously did not exist before. Trouble is, I cannot access any of my files that were created under the Administrator named user previously. Any ideas?
Solved...due to Win10's obsession with security, it automatically disables the Administrator account upon upgrading. To fix, right click on the Windows pane in the lower right/Computer Management/Local Users and Groups/Users/double click on Administrator/uncheck Account is Disabled, click Apply and re-login
