login - Cannot log in on Windows 10 with one of the accounts

My son has his own account on my computer (mine is administrator, his is a normal user).
For some reason I cannot log in using his account anymore.
(Edit: I see now how this may sound like I was trying to sneak in. What I meant to say is that he's unable to log in and I'm trying to solve that problem).
More precisely the problem is this:



  • I select his username and enter his password

  • the credentials are accepted because I see his desktop, though only for a split second

  • then it redirects to the photo that Windows shows before logging in


If I then log in as myself and open Task Manager, I can see in the Users tab that there is in fact a session for him (status=disconnected). Also, on the Details tab, I see a number of 'standard' processes running under his account.


I noticed the he has a process called lockapp.exe running. I don't have this program running under my account.
I tried killing that process and logging in as him again. The same problem occurs but the lockapp.exe process is not recreated for him.


Some more info:



  • I tried making him admin temporarily and log in as him using Remote Desktop from my laptop. More or less the same problem although now it just hangs.

  • I have RDPWrap installed. That's a program that allows for multiple accounts to connect using Remote Desktop simultaneously. I've uninstalled it but that didn't solve the problem.

  • MalwareBytes and a search for lockapp.exe's SHA-1 on Google come up clean

  • Windows defender reports no problems

  • Currently running Windows 10 Version 1709 for x64-based Systems (KB4058702)


Does anyone have an idea what could be going on.
