    How to fix "The User Profile Service service failed the sign-in"


    User Profile could not be loaded.

    I Can't log into my computer, I'm using my desktop but need to know how to fix this. I'm using a toshiba satellite a665-s5170 Laptop

    I also don't have any other user accounts. I don't know how to reboot, I do know that there is a reboot partitioned into my HDD.

    Hello Yanall, and welcome to Eight Forums.

    User Profile Service failed the sign-in - Fix in Windows 8

    You might also see if you may be able to do a system restore at boot using a restore point (if available) dated before this happened to hopefully fix this.

    If that doesn't help or not possible, then you might see if the tutorial below for this error may. It's for Windows 7, but still applies to Windows 8. Be sure to do the "In Preparation" section first to hopefully be able to sign into Windows 8.

    System Restore - How to Do in Windows 8

    Here are the Windows 8 tutorials for the items in the tutorial above to help. Please ask any questions that you may have.




    Hope this helps,
    Shawn
