Can't login with new local users in windows 10
You might have a corrupt Default profile. (This can apparently occur when upgrading to Windows 10.)
When logging in for the first time with a new user, the Default profile is copied to create the profile for the new user. If it's corrupt, this can cause the login to fail for the new user.
Try the following steps:
- Take a zip of C:\Users\Default from a Windows 10 installation that doesn't have this problem
- Rename C:\Users\Default on the Windows 10 install that is having problems, to Default.Old
- Unzip the non-corrupt Default profile into C:\Users
Now try again.
