Windows 10: Why is my Laptop PC service failed to sign-in?

Why is my Laptop PC service failed to sign-in?

:)

 

The User Profile Service service failed the sign-in. User profile cannot be loaded.

Hello,

When attempting to login to my computer, I get the following message:

"The User Profile Service service failed the sign-in.

User profile cannot be loaded."

I referred to this Help article,You receive a "The User Profile Service failed the logon” error
message,

but the only difference is I only have one user profile on this computer. So, I can't login with another user to go through the steps listed in this post.

Any suggestions?

Thanks,

 

User Profile Service service failed the sign-in.


I am trying to create new user logins on my laptop for my kids - I have successfully created user accounts that show up at startup, but I get the following error when I enter the passwords and try to login:

User Profile Service service failed the sign-in. User profile cannot be loaded.

I have tried multiple solutions from this forum, including regedit - their accounts do not show up on the ProfileList, and changing the permissions in C:\Users\Default to "Replace all child object permission entries from this object".

Also, deleted and re-added the accounts. Any other suggestions?!?!?!?!?!*Sleepy*Sick*Sleepy*Sick*Sleepy

Brink:
I am using registry editor from command prompt. Drilled down to c:windows\system32\config inside the Load Hive dialog window. Have selected (checked box) the SAM file; clicking on Open opens error message that says:


SAM
This file is in use.
Enter a new name or close the file that's open in another program.

I am at a loss, since I am not running any other program!

Any suggestions?

The SAM file is listed as being 64KB file size.
