Vista - The User Profile Service failed the logon. User profile cannot be loaded.

i have two of the same number folders...the first without .bak...and the second one with it...i tried to follow your instructions but it wont let me rename them =/

Hello Kenny, and welcome to Vista Forums.

You can also try doing a System Restore at boot using a restore point dated before you got this error to see if it may be able to fix this for you.

Hope this helps,
Shawn

unfortunatly i tried that and didnt work =(

Kenny, could you post a screenshot of this location in the registry? It might help determine why it may not be letting you rename the SID key.

OMGOSH...i tried system restore again and it worked!!!...turns out i put the wong time!!!...how embarrasing

but thank you soooooooo much...if it wasnt for this forum i would have never even thought about syster restore

THANKS A LOAD =D

You're welcome Kenny. I'm happy to hear that you got it sorted.

.. Shawn..
I'm Sonny. Came from Indonesia. I have tried to follow the step. But it cannot be edit or error while rename it. What should i do?
Thanks Shawn..
Will system restore delete all the data i've been working for?
Forgive me for my bad english...

Hello Sonny, and welcome to Vista Forums.

A System Restore will only affect Vista system files, installed programs, and drivers that were installed after the date of the restore point. It will not affect your user files (ex: documents, data, etc...) or settings. It may be able to fix this error for you.

Hope this helps,

Hi there -

So, I found this tutorial after I'd done 3 system restores. I had also done at least 3 scan disks. I was finally able to log onto my account, but it was a temporary account, and according to the hard drive capacity, my existing files were still there. I downloaded recuva to find files - no luck. I did option one, was able to rename the 2 files successfully, shut down computer and rebooted, crossing my fingers...now I am back to where I was yesterday morning when this mess first started - user profile service failed log in. I can start in safe mode. I cannot do a system restore - gives me the message that no system restore point is available, and it will not let me create one. Should I try option one/two again in safe mode? I'm about ready to say the heck with Vista and install XP...

Any feedback is appreciated...thanks~

Hello FancyNancy, and welcome to Vista Forums.

Your user files may still be in the C:\Users\(user-name) folders.

Since it is booting you to a temporary account, then you might give this tutorial below a try instead.

User Profile Error - Logged on with a Temporary Profile

If it still does not help, then your use account may be corrupted beyond repair, and a reinstall may be needed.

Hope this helps,
Shawn
