I have been looking at this issue for a while.

I am running Windows 10 Pro 64 Bit Version 1703 OS Build 15063.540

I have tried to create a new user tonight, I tried to add my son through microsoft family and the account would simply not login, I switched him to an administrators account and I got in but the account is badly damaged, no startmenu, no background no nothing.

I removed him from my family and decided to create an account manually using

net user /add testuser1 <password>
net localgroup Administrators testuser1 /add

both commands executed successfully.

When I log in I am greeted with a totally black background, the taskbar is there but the start menus isn't there and I can't launch anything at all not even cmd.exe from the run box.

I'm not sure why this has happened I have 3 accounts on the machine that work perfectly and my log is not full of errors. I am wondering if the accounts are based on some sort of template that may be corrupt but I am a little beyond my ops knowledge.

This is a dev box albeit a home one and would incur significant effort to reinstall so before I do that does anyone know how to fix this? I can't create new accounts that I can use to log in on. At least interactively.

Also worth a mention is if I create the user as a normal user and not an administrator it simply doesn't leave the login screen but immediately logs them out.

Interestingly all other accounts were created before creators update, Hmm I wonder.

  • Wouldn't it be easier to delete your son's profile and simply create a new user? – Ramhound Sep 7 '17 at 20:43
  • All new users are broken, that's the point so thats what I did and all users I create are very badly broken indicating they suffer from the same issue. I've done all the obvious stuff like sfc, and checking my updates with dism etc. – krystan honour Sep 7 '17 at 20:46
  • "I am wondering if the accounts are based on some sort of template that may be corrupt but I am a little beyond my ops knowledge." Just to double-check, nobody deleted or modified the C:\Users\Default folder on that machine, did they? – Run5k Sep 7 '17 at 20:49
  • There are two things there called default they are 'Default' a directory and a junction called Default User which points to c:\users\default, both are hidden – krystan honour Sep 7 '17 at 20:52

    I hate to recycle what everyone eventually says to do with Win10, but try running dism /online /cleanup-image /restorehealth && sfc /scannow, then reboot. Once that's completed, create a local account for him. If all goes well, you can link his microsoft account later. (Nice question syntax, btw. Love proper english :D) – Dooley_labs Sep 7 '17 at 20:55

I fixed this by going into backups and restoring my default user profile, whilst running a new backup after restore I have since found my spanky new ssd is throwing CRC errors, trying to get that replaced on warranty.
