The User Profile Service failed the logon.
I've been using Windows Vista Ultimate for almost three months now, and all
of a sudden tonight I couldn't log on to my laptop. Every time I tried I
received the message "The User Profile Service failed the logon. The User
Profile failed to load." I had successfully logged on to it only five hours
earlier, so I did not understand what could be going on.
Fortunately after Googling the error message (I originally used Microsoft
Live Searct, but did not get any results), I found someone who had a similar
error and had found that his profile had entered a backup state. I logged on
with my domain administrator account (it's good to be the king sometimes) and
examined the keys under HKLM\Software\Microsoft\Windows NT\Current
User\ProfileList\ and was able to find the key for my user id SID. Sure
enough, the key had a ".bak" appended to it and there was an identical one
that was set to a temp directory. I renamed the other key, removed the
".bak" from mine, and changed the State property under my key to 0. This
allowed me to log in.
Does anyone know what might have caused this issue? If this is a bug, its a
pretty severe one, as I can just imagine a help desk trying to resolve this
over the phone with their laptop users who all of a sudden can't log in.
Re: The User Profile Service failed the logon.
I'm new to Vista so I asked my wizz friend and then I managed to solve
the problem:
1. I closed down.
2. Turned computer on and immediately pressed F8 repeatedly until I got
"Advanced Boot Options".
3. used the down arrow to select "Safe Mode" and pressed enter.
4. computer then opened eventually in the funny look of safe mode, with
a "Help" window.
5. In the help window there is an underlined "What is System Restore?"
Clicking on that gave me the answer and "Click to open System Restore"
6. I clicked on that and a new window came up recommending restoring to
a previous state before windows update which I had done before the fault
occurred.
7. I clicked OK and after a bit of whirring all came up OK. Can you
imagine how pleased I felt?
8-. Incidentally I had also changed the display font size to the larger
size just before the fault occurred so while in Safe Mode I managed to
remember how I had done that and changed it back again as that may have
caused the fault.-
Re: The User Profile Service failed the logon.
turn on your computer then hold press F8 You will see on the screen "
Repair Your Computer" then Enter. Don't choose Administrator if you
don't know the password use your own administrator user name and your
password,. then press Enter.
On the screen
You'll see on the first Category "Startup Repair" and the second one
"System Restore"
click on Startup Repair then when Your done doing it restart your
computer. if doesn't work try the second one System Restore then click
on it. again when your done Restart your computer.
Re: The User Profile Service failed the logon.
I had this same problem and after reading all the posts here I finally managed to put all the piaces together because I am not very familiar with al this computer Vista repairing.
1. Couldnt log on no more, just like tat out of the blue
2. I hae only one user so I had no way to log on on my laptop
3. I managed to go in SAFE MODE:
-turn on your laptop ( or restart if it is already on) and right after the stat up screen disapears press esc (this will bring you to a black screen with some options)
- Press F8 for advanced options > Safe Mode
4. I Tried to run Windows recovery
- HOWEVER, I had NO recovety points, so Step 4 was useless for me.
- If you do have one, It will recover your settings to an earlier point and it will be fine
5. Open Regedit
-C/Windows/regedit (double click on the regedit file )
- This opens a new window
6. Go to (left side of the panel)
-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
7. You will see folders named with waht seemes like a serial key (User keys)
-one of the long named ones should have a ".bak" suffix (or extention like in a picture file it will be ".jpg" in "photograph.jpg")
- there will be aother key with theexact same name but withut the ".bak" extention
- rename that key (right click>rename> go at the end of the name and add a ".old" or whatever just so it is different
- now that you have renamed the key, you can go back to the main key who had the same name but had a "bak" suffix.
-Delete ONLY the extention ".bak".
(If you try to do this before renaming th other key it wont work as the 2 keys will end up having the exact same name so follow the order)
- Now you have a key without extention and a key with extention ".old"
- stay on the one without the extention (or click on it if you clicked somewher else in the mean time) and you will see some info in the right panel.
- At the bottom ,double-click on here it says "State" and change the value that you have for 0.
8. Close everything and Restart your Computer
9. It should work, and my files are all still there.
10. You should set up the windows to make restore points automatically so tht you dont have to go through this again and set up one more user (admin)
I dont know what it causes teh problem, I was thinking maybe some updates, anyway I found this:
"Some programs like the Google Updater (if you added the Google Toolbar, Chrome or Google Earth) has been
known to cause this issue."
Re: The User Profile Service failed the logon.
I just wanted to take a quick moment and say thank you to the post from John Bailey, bazkennedy and cgos. You were all helpful but these three post led me to a successful fix.
I recently found myself faced with the logon problem, basically saying The User Profile / service failed the logon / user profile can not be loaded. I was dead in the water because it was the admin account. I had other accounts on the computer so after logging in on a second account. I went into the search bar just above the vista symbol at bottom left and entered cmd, which showed in the search window the cmd.exe command. I right clicked over the cmd.exe and clicked run as a administrator. Just type in the password and your in the DOS prompt. Then type regedit and then follow the above posts information. I did see the .bak at the end of the values. I then followed more of "cgos" information (above post) by renaming the extra identical value (without .bak) just by ending it with.old. I then removed (just) .bak from the value. Then replacing the 8 from the 8000 in the right hand side "state" value. Then logged off my second account and then onto the admin account and all is well.
It seems a little tricky but after figuring out how to run as admin from a second acct everything went quickly and smoothly after that.
Good Luck.

JUJU GOGO.
I wanted to say thanks to you and the others....I was quite Scr*wed this morning when my computer got a security update shoved down its gullet and promptly rebooted and failed to let me logon....profile was hosed. A qwik call to our help desk and the AF person there told me I probably lost all of my files (MY WORK!!!!) under that profile.....great.
I went back logged in as local admin and found this site and this fix.....presto!
It works....nothing but a couple of hours lost!
Thanks!
Re: The User Profile Service failed the logon.
I had a friends laptop with Vista Home Premium with the "User Profile Service failed the logon" problem. But I checked the registry didn't see any .bak files or anything out of the ordinary. So, what I did was set the profile I was trying to make a standard user that wouldn't sign on an Administrator. I then was able to sign in, then convert it back to a standard user. All works now. Hope this helps. Must be something in the group policy settings or some kind of antivirus program that changed the settings??
