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.
