Windows 10: User profile sign in error

I’m having huge problem on my Windows 10 PC. Please help. One day out the blue sky i got the issue saying “The User Profile Service service failed the sign-in. User profile cannot be loaded.” There is only 1 user account and it does not wanna sign in. Booting in safe mode doesn’t work. A complete reset doesn’t work, as well as the startup repairs and all the other available troubleshooting methods i’ve seen on the web. So just skip all the methods that include searching in a start menu or whatever requires a fully signed in normal windows work, because i can not use anything outside of the si

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,

 

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

 

Win 10: Creating a member (child) profile getting error that "The User Profile Service failed the sign in" User Profile can not be loaded

Hi Simonalee,

Thank you for posting in Microsoft Community.

From the description, it appears that you are not able to sign in to user account. This issue appears if the user profile is corrupted.

I suggest you to remove the account and then try to create new user profile.

To do so:

1) Type settings in the search box and then click on Settings app.

2) Click on Accounts and then select Family and other users.

3) In the right pane, try to add the family member and check if it helps.

If the issue still persists, Check to see if it works by converting the Microsoft Account to Local and then back to Microsoft Account. Here`s how:

• Go to Settings from the Start Menu.
• Click Accounts. Under Your Account, click Sign in with a Local Account instead.
• Follow the instructions. Sign Out and Sign in.
• Then convert back to Microsoft Account.

To connect back to the Microsoft Account, you will perform similar steps:

• Go to Settings from the Start Menu.
• Click Accounts. Under Your Account, click Sign in with a Microsoft Account instead.
• Follow the instructions. Sign Out and Sign in.
• Your account should now be connected again.

Let us know if this helped.
