• The user profile Service error

  I got the error message saying that the operation has failed, I found instructions to fix, but it is the administrator account that is corrupted how can I fix the user accounts?

  Hello jedboston,

  Since you can not log on with the administrator account on the computer, we should see if we can in safe mode and if not proceed from there. Try, follow these steps.

  1. reboot your computer and press F8 multiple times until you see a menu similar screen, if you see the Windows startup screen, then repeat this step
  2. highlight and press enter on Mode safe mode with command prompt. Try to connect to it. If it still does not work, proceed to step17
  3. If you are able to connect, once the command prompt appears, type: net user administrator password / active: Yes (you can specify the password for the administrator account.)
  4. If you get a message "the command completed successfully" and then restart your computer by typing: shutdown - r
  5. start again by pressing F8, but this time choose just the SafeMode.
  6. you will be able to log in as administrator with the password set in step 3
  7 hit (windows logo) + r.
  8. type regedit
  9. once the Registry Editor opens, search for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
  10. in the left pane, find the one that begins with S-1-5... and ends with. BAK; If you can't find one, go to step 15
  11 right-click and click Rename, and then change it. TO BAK. BK
  12 right-click with the same numbering but without the. BAK and Add. BAK add at the end
  13. right click on the one that you have renamed in BK and clickRename, remove the. BK
  14. Subsequently, you have activated the. BAK to the end of the second entry in the first. That should probably fix your problem.
  15. If you do not find one. BAK then try this: open Explorer Windows for C:\Users\Default\AppData\Local\Application data
  16. If you find an other Application Data below the one you are on, and then delete. Who should probably also solve your problem.
  17. If you can not log in Mode safe mode, restart and press F8 until you see the menu again, and then press enter highlightingRepair your computer
  18 wait for all the Windows files to finish loading, then hitNext when it asks for the language of the keyboard.
  19. try to connect here also, choose your username in the menu drop-down, type the password, then go to step 23
  20. If it still doesn't work, then if you still have your Windows installation CD, put it in, and then restart your computer.
  21. press F12 until you see a menu of boot options, choose boot from CD
  22. the language of the keyboard and then click Next. Find repair your computer for a little below the center-left.
  23. choose Open command prompt and type: net user administrator / Active: Yes password (here again you can specify a password)
  24. close the command prompt and click on restart and go to step 5

  Source: I receive error message: the user profile service has no logon. Unable to load the user profile

• Fix using Microsoft 50446: the user profile service service has no logon. User profile cannot be loaded.

  About Microsoft fix 50446 found here http://support.microsoft.com/kb/947215#letmefixit for the user profile Service error, I have three questions about it:

  1. what exactly does this automated solve this downloadable program change / do?

  2 would you recommend to fix "user profile Service service has no login" or would you recommend that the problem resolved manually?

  3. currently, when I log on my computer's built-in Administrator account using safe mode, I am unable to change any other user account or create a new user account.  I'm unable to connect to is account only administrator of my computer.  If I delete this account, I then will be able to create a new administrator account by using the built-in Administrator account on the computer that is running in safe mode?

  Any help on this is greatly appreciated.  Thank you.

  Mr Wizard is essentially the same as the manual process. If there is a difference, I'm not aware.  Personally, I prefer manual processes that I feel I have more control - but others prefer the automated process, because it is simpler.  The choice is yours and I don't think in the long run it's important.

  Question 3 is more difficult to answer.  As the only administrator account on the system, remove leaves you only with the built-in Administrator account which, currently, is not working as you can not use it even to create another administrator account.  Here, the hope is that the patch will solve the underlying problem and the high administrator account will work as normal once the fix is completed - however, I can't guarantee that will be the case because I've never done this procedure when the problem of account is the only account to administrator on the system.

  It should work, but if it isn't then you will be in the situation where you have no active and functional administrator account (if even the built-in Administrator account does not work as an administrator account - as seems to be the case at the moment, but can change once completed correction - or for some reason any cannot be enabled or accessible) and the only solution to this problem is a clean install.  For this reason I recommend you make a backup completes before attempting this, unless your data will be safe.

  I should add that I'm not sure that you have many choices, because this is pretty much the way to solve this problem and I do not know other solutions that work.

  I hope this helps and that I could be more reasssuring, but that's as far as I know the problem, the fix, the situation, the solution proposed and the potential consequences.

  Good luck!

• cannot get past error - could not connect the user profile service

  My HP desktop computer has windows 7 - I can't get past - error message "user profile service failed to connect ' & 'impossible to load the user profile'!"  By clicking on the ICON that displays windows closes and repeats the error message read... a new user account must be defined the user upwards and copy the previous settings account - but I can't get there.

  Hello

  You can try the following.

  Shut down the PC.  Tap away at f8 that you start the PC to enter the Windows Recovery Console.  Use the arrow keys to select Safe mode and press ENTER.  If windows will load in this mode, on the Start Menu, click principally made programs, click Accessories, click System Tools and run the system restore.  Choose a restore point at least 24 hours prior to the issue of logon and then proceed to the restoration.  When you are finished, Windows will restart as normal in order to check if you can now connect correctly.

  Another option if the above does not help is as follows.

  Shut down the PC.  Tap away at f8 that you start the laptop to enter the Windows Recovery Console.  Use the arrow keys to select "Start using last good known Configuration" and press ENTER.

• Error 1051: User profile Service has no logon

  Mr President.
  I use a real operating system Windows Vista Home Premium SP2 with my laptop Lenovo Y430. I have recently updated to SP1 to SP2 Windows Update online. last week when I tried to log in one of my user accounts, the above-mentioned error popped up on my screen. on further verification, I found that the "user account" does not exist in the c:\user\(account name folder). I could not find the same in the registry editor "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList".

  I've traveled all your forums to get help, including http://support.microsoft.com/kb/947215. even installed the "Microsoft Fixit" given on the same page, but it did not help. I even tried to restore my system to an earlier point.

  In addition, when I tried to stop/restart the "user profile Service", the same mistake invited each time. but when I stopped/restarted the "user profile Service" after the removal of the user of the control Panel\User account account, the system didn't invite me with the error. and then; even after the service is restarted, and then creating a new user, I was unable to login with this user account.

  now I find myself with a single administrator account to work with
  Please suggest

  Thank you in anticipation

  If you cannot connect to your admin account, no tutorials can help you because they need you to connect to an administrator account to carry out the instructions.

  See if the following can get an admin account...

  Go to Safe Mode...

  Restart your computer > immediately and repeatedly pressing the F8 key until you see a black and white screen. The top/down arrow and select Mode safe mode with networking.

  Now, while in safe mode, you perform one of the following?

  1 can connect to your account admin without the error message?
  If so, do. Then do a system restore. Choose a date when you were free to login to your account admin as your restore point.

  http://www.howtogeek.com/HOWTO/Windows-Vista/using-Windows-Vista-system-restore/

  If the system restore does not slove the problem, then use this tutorial

  http://support.Microsoft.com/kb/947215

  2. If you are unable to log in to your account administrator in safe mode, you see another administrator next to your account?
  If so, you are lucky. This is the built-in Administrator account.
  There is, by default, no password.
  It could connect and do the system restore.

  If the system restore is not enough, then perform the tutorial even as above:

  If you can't do or of what precedes, I'm afraid you will have to re - install your Vista.
