    'User Profile Service service failed the logon

    Can someone PLEASE help me... My computer hasn't loaded for 3 days now. It just comes up with:

    User Profile Service service failed the logon.

    User Profile could not load.

    What do I do? I cant get on the computer at all, because i only have one user profile on my computer. I'm in school, and I don't really know much about computers. What could have caused it? And how do I fix it? Please help, I really need to get to some of the files on my computer... Please!

    Many times, that's the kiss of death. Unless, you have an
    image backup, you might have to reinstall Vista.

    You might try booting into safe mode and running
    System Restore. Or, using the install disc to boot from
    and running System Restore or CompletePC Backup.
    Have you ever made a CompletePC Backup? That option
    is only available for the Ultimate and Business versions.
    You could try the repair option offered when booting
    from the disc. Don't think it'll work for that though.

    Sometimes rebooting a few times will "fix" that particular
    problem.

    If you want, there's one more option- try a "repair install",
    Scroll down to "Here's How" to get to the meat of it;

    hi george, done a little search on MS for you hope this helps, here's the link
    http://support.microsoft.com/kb/947215/en-us
    this may help too but requires editing the registry, if done wrongly will screw up your computer completely! be very careful

    another option maybe worth trying is to boot into safe mode & see if you can
    create a new user account to log on as

    I've just had this problem on my computer, and I just fixed it.
    It seems to be caused by a horrendous bug in Vista that renames your User
    Account Profile as a backup, and then creates a new user account with the
    same name but with nothing in it.
    I googled it and followed several bits of advice but none of them worked,
    but I managed to fix it with a combination of ideas.
    This is how I did it:

    1. Boot up in Safe Mode. To do this, hit the F8 key while the computer is
    booting, and then scroll down to the "Safe Mode" option and press enter. On
    my computer the user account icon appeared, but bigger than normal, and I
    clicked it and it loaded my desktop in safe mode. It came up with an error
    bubble saying that my user account hadn't loaded properly, but i just ignored
    this.

    2. Click the Start Button and in the white "Start Search" space at the
    bottom type "regedit" (without the quotation marks). This will open the
    registry editor.

    3. In the left-hand pane, navigate by clicking the little triangles next to
    the following folders:
    HKEY_LOCAL_MACHINE
    SOFTWARE
    Microsoft
    Windows NT
    CurrentVersion
    ProfileList

    You should now have a list of folders all starting with S-1-5- and then a
    number.
    (You might need to drag the divider between the 2 panes of the window across
    so you can read the whole folder name)
    Look at the end of each name and you should see one with .bak at the end of
    it, and there will be another one above it with exactly the same name but
    without .bak at the end.
    The one that's got .bak at the end is your old User Profile that Vista has
    now made into a backup, and the one without .bak after it is the new empty
    User Profile that Vista has created.
    Just to check that this is the case, have a look in the right-hand pane for
    each of the 2 folders and look at what's written after "ProfileImagePath".
    For the folder with .bak at the end it should say C:\Users\ and then your
    usual User Account name, and for the one that doesn't have .bak at the end it
    should say C:\Users\TEMP.

    What you need to do now is to rename the folders in the left-hand pane so
    that the one with .bak at the end changes back to being the one containing
    your proper User Profile and the new one without .bak at the end becomes the
    backup. Do do this follow the next step:

    4. Right click on the folder with .bak at the end and then click "rename",
    and just change the ".bak" part to ".bk" - i.e. just remove the "a" from the
    middle - (this is just to allow you to change the other one to have .bak at
    the end). Press enter or click on some blank part of the screen for the
    change to take effect.
    Then, right click the one that doesn't have .bak at the end and click
    "rename". Remove the .bak from the end and press enter or click anywhere on
    some blank part of the screen to accept the change.
    Then, right click on the one that now has .bk at the end, choose "rename"
    and add the "a" back into the middle, so it now has .bak at the end. Press
    enter or click on blank park of screen to accept the change.
    Close the regedit window.

    5. Click the Start Button and then "Restart". It should work now. Fingers
    crossed. :)

    Not only did this post bring my computer up and running again, but it gave me
    back all my research that I have saved for my thesis. Looks like I will be
    making a copy now. This post was VERY helpful.

    also says you should set the RefCount and State back to 0. I notice
    my RefCount is set to 3. Any idea what 3 means? Should I set it back
    to 0?

    I went through the process described below by Marek. I previously saved
    all of the Word documents, but all of my MS Mail was gone after the
    process. Does anyone know where to find it on the computer? I have
    looked on the corrupt User Name, but cannot find it there.

    The options in this tutorial may be able to help you. Be sure to also
    check the yellow TIP box options at the top as well

    just remember to restart at boot and (Vista) hold down F8 the entire
    time until your little blue bar at the bottom has finished; then press
    F8 again to enter boot options

    Sorry, cat hit the enter button on the previous reply....

    Marek's rename switch of the user profile registry entry worked flawlessly,
    without any additional work required. The profle problem occurred on this
    computer after the installation of the last Microsoft patch/security fix
    update in October. Perhaps something in that update tries to backup the user
    profile and does not finish it correctly. Just a guess. Thanks, Marek for the
    2 minute fix.

    I tried what Marek suggested, but when I rebooted and tried my old password, it gave me the same "User Profile Service service failed" message. What can I do next? I really don't want to loose all of my music, pictures, etc...Thanks!

    THANK YOU Marek. Your steps were a lifesaver for me today. It worked in XP, with my profile degrading over the last few days... It's good to have a backup computer for troubleshooting too :)

    This is a separate issue and should have been posted as a "New Thread"
    instead so that you could get better support on it. Just something to
    remember for your next post.

    Check to see if you have a "C:\Windows.old" folder. If you do, then
    everything should be in that folder under the same C:\Users\(user-name)
    folder. You might also see if doing a search on the C: drive for one of
    the files or one of the file types (ex: *.txt) in it to see if they may
    show up in the search results.

    When you upgraded, it copied the previous installation into the
    C:\Windows.old folder. Since you had a user profile error at the time,
    it may not have copied over your user files though. Afterwards, it would
    have formated your drive and installed Windows 7 on it with the folder
    above.

    It doesn't look good so far. Check to see if you have either the
    *C:\$INPLACE.~TR* and *C:\WINDOWS.~Q* folders. If you do, look to see if
    you user files may be in one of them as well.

    If you had just deleted them in your old installation, it may have been
    possible to recover them using a program like "Recuva" or "Shadow
    Explorer". However, since you upgrade the OS and they are not in the
    usual folders above, then I'm afraid that it looks like they are gone
    for good. :(

    First of all let me say, Thank you Marek. If it hadn't been for you I
    dont know what I would have done. The only other comment I have is that
    your step 4 kind of confused me so I did what I thought was right and it
    works. Other than that I followed your directions step for step. My
    changes are in all CAPS below:

    4. Right click on the folder with .bak at the end and then click
    "rename",
    and just change the ".bak" part to ".bk" - i.e. just remove the "a"
    from the
    middle - (this is just to allow you to change the other one to have
    .bak at
    the end). Press enter or click on some blank part of the screen for
    the
    change to take effect.
    Then, right click the one that doesn't have .bak at the end and click
    "rename". ADD .bak TO the end and press enter or click anywhere on
    some blank part of the screen to accept the change.
    Then, right click on the one that now has .bk at the end, choose
    "rename"
    and REMOVE .bk FROM THE END. Press
    enter or click on blank park of screen to accept the change.
    Close the regedit window.

    Again let me say thank you Marek. If I was wrong in doing any of this
    somebody please let me know.

    Your step by step instructions was really helpful in fixing this bug. Thank
    you so much.

    I also had the same problem and followed the steps you suggested and
    the issue is now resolved.

    RE: 'User Profile Service service failed the logon

    Although this post does the work notice that step 4 above is messed up. The
    main idea is: i) Go to the directory without extension and add (rename it) an
    extension .bak. ii) Go to the directory with *.bak extension and remove it
    (by renaming it). The following link has the correct steps
