Synopsis
This will show you how to fix the error :
The User Profile Service failed the logon. User profile cannot be loaded.
How to Fix the Error "The User Profile Service failed the logon. User profile cannot be loaded."

information   Information
When you log on to Vista or Windows 7 using a temporary profile (user account), you receive this error message:

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

For more information, see:
Error message when you log on to a Windows Vista-based or Windows 7-based computer by using a temporary profile: "The User Profile Service failed the logon. User profile cannot be loaded"
Note   Note
CAUSE:

The jury is still out on the exact cause, but so far :
  • This issue may occur if the user profile was manually deleted by using the command prompt or Windows Explorer by a user or by some program. A profile that is manually deleted does not remove the security identifier (SID) from the user profile list in the registry. Since the SID is still present, Vista will still try to load the profile by using the ProfileImagePath that points to a nonexistent path. Therefore, the profile cannot be loaded.
  • This can also be a issue with the user profile entering into a backup state.
  • Manually renaming the C:\Users\(User Name) user profile folder.
warning   Warning
If you have this error message below instead, then see: How to Fix the Error "Your user profile was not loaded correctly! You have been logged on with a temporary profile." in Vista

Your user profile was not loaded correctly! You have been logged on with a temporary profile.

Changes you make to this profile will be lost when you log off. Please see the event log for details or contact your administrator.

Tip   Tip
If the steps in the tutorial below do not help or you wish to try this first, then:




STEP ONE
Log on to the Computer
warning   Warning
You must be logged on to an administrator account using either step 1 or 2 below before you can move on to do either the OPTION ONE or OPTION TWO sections.

1. To Log on to another Administrator account.
NOTE: If you do not have another Administrator account, then proceed to step 2.​
A) Go to OPTION ONE or OPTION TWO.​

OR
2. To Boot into Safe Mode and Use the built-in Administrator account
NOTE: You may not need to enable the built-in Administrator account. If this was the only normal administrator account you had, then Safe Mode should automatically boot into the built-in Administrator account.​
Tip   Tip
If you cannot boot into Windows and do not have a Windows installation DVD, then you can create and use the boot disc below to boot into Safe Mode with instead.
Tip   Tip

Windows 7: (Option Two at link)
Vista: (Option One at link)

A) Boot into Safe Mode (in Vista) or Safe Mode (in Windows 7).​
B) If Safe Mode did not boot into the built-in Administrator account, then enable the built-in Administrator account. If it did, then go to step 2D.​
C) Log off in Safe Mode, and then log on to the built-in Administrator account to logon with that account in Safe Mode.​
D) Go to OPTION ONE or OPTION TWO.​




OPTION ONE
To Fix the User Account Profile

1. Open the Start menu.​
2. In the white line (Start Search) area, type regedit and press Enter.​
3. If prompted by UAC, either click on Continue (Vista) or Yes (Windows 7).​
4. In regedit, go to: (See screenshot below step 5)​
Code:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
5. In the left pane, look for the S-1-5..... folder (SID key) with the long number that has .bak at the end of the numbers.​
(See screenshots below steps 6A and 7B)​
NOTE:
A) In the right pane, look at the ProfileImagePath to verify that this is the user account profile that has the error.​
B) You may have another S-1-5..... folder (SID key) above it with the exact same number without the .bak at the end of it.​
6. If you have Two S-1-5..... folders (SID key) with the same Number
NOTE: This is if you have two S-1-5..... folders (SID key) with the exact same numbers, but the second (below) one has the .bak at the end of the numbers.​
A) In the left pane, right click on the first (top) S-1-5..... folder (SID key) that does not have .bak at the end of the numbers and click Rename. (See screenshot below)​

OPTION TWO
To Delete the User Account and Create Another One

warning   Warning
You can do this option if you do not care about losing the user account and the contents in the user folders. Your programs will still be installed, but you will need to create new shortcuts for them afterwards.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
6. In the left pane, click on one of the S-1-5..... folders (SID key) with the long number in it.​
NOTE: It may have .bak at the end of it.​
A) In the right pane, look at the ProfileImagePath to see if this is the same user account that you deleted in step 1 above.​
B) Repeat step 6 until you find the one that you deleted in step 1 above.​
NOTE: If the user account is not here, then it has already been removed when deleted in step 1. Go to step 9.​

7. To Backup the Registry SID Key
WARNING: You should backup this SID key to be safe in case you delete the wrong one in step 8 below.​
A) Right click on the SID key, and click on Export.​

Hi! Having *same*issue . . .
Why can’t you just 'Delete' the [ Ntuser.dat || Ntuser.dat.log || Ntuser.ini ] files from the corrupt profile? (I'm sure there's a reason ~ jw! & bc that would be to ez??)
TIA!
 
Hi Brink or Shawn! I've tried option one and option two for me and it didn't work. In option, I only have ONE S-I-5.. number and unfortunately, nothing happened. While doing option two, when i tried creating another account in safe mode (using the admin account, btw the admin account is the one that has the problem), I can't access the "Manage another account" option. I clicked it many times but nothing happened. What should I do? I can't create another account using safe mode of the admin account that has the problem, haha, sorry for the wordplay.
 
Hello bbtbbt02, and welcome to Vista Forums.

You could also try doing a System Restore at boot using a restore point dated before the this error to see if it may be able to fix this. :)
 
How can i do a SYSTEM RESTORE at BOOT? Can I do this while on safe mode? If you have time, can you please instruct me how to do it. I'm sorry for the trouble but I don't have much knowledge about computers, thanks!
 
The link in my post above can help give you step by step details on how. If you have any questions, then please feel free to ask.
 
Please give more details about what you mean that nothing happened? You might see if you may be able to do a system restore while in Windows. :)
 
Okay. I never done any system restore in my laptop ever since I bought it. The first thing I do, I go to the safe mode since I can't open my user account. While in safe mode, I accessed the SYSTEM RESTORE. There is only one system restore point since I haven't done any right? I followed the steps and my laptop restarted. When opening in WINDOWS, the same message "The User Profile Service failed the logon. User profile cannot be loaded." appeared again. What should I do next?

Also, what I have in mind is to have a new user account, but I can't access the MANAGE ANOTHER ACCOUNT option in the USER ACCOUNT in Control Panel (this is the reason why we come up with the SYSTEM RESTORE idea right? If you see our threads before.) Now, I want to ask, do you know how to make a USER ACCOUNT using COMMAND PROMPT?

May you answer my two queries here. Thanks Brink for your concern and replies.
 
In that case, see if you may be able to do the Step One section to enable and log in to the built-in Administrator account.

If you are able to, then you could use that account to create a new account.
 
i am trying to squeeze a few more months?hopefully years out of my sony vaio desktop, last week i started getting the user profile failed the logon. i was able to fix it using the rename the files tutorial as shown earlier. but now my files and pictures are gone. how do i get them back?
 
Hello Jenjav, and welcome to Vista Forums. :)

Double check to see if there may be another "C:\Users\(user-name)" folder that may contain them.

i found them in another folder, as you suggested, do i copy each file folder to new user account? can i rename the new user account, both say master but the new one with "test-pc".
 
Great news.

Yeah, you can just copy the files over into the same corresponding folders (ex: Pictures, Documents, etc...) of the working account. :)
 
Hi Everyone,

I have a dual boot system which comprises Vista Home Premium 64 bit which had XP added to it later (because I needed that OS,too), and the system has run fine for over 6 years. One of our Vista accounts has "failed the logon" and instantly logs off when ok is pressed. As the system is dual boot, there are no restore points. I have followed the advice to backup regedit to my desktop (I am administrator, fortunately) and have tried looking into the regedit for the HKEY LOCAL MACHINE etc. Below that I have managed to expand lists of very long numbers but they don't have the .bak after them. Instead two of the identical number lists each has "classes" written after it. The data in the locked account is intact as far as I can determine by viewing from XP. I have also run extensive scans by two kinds of antivirus and anti-mal/spyware.

Has anyone any idea how I can find the errant .bak files? Should I be looking for these or for something else? I have seen someone in another forum, I think, suggesting deleting asterisk.sqm files, yet I do not know what these might be other than temporary files and do not know whether this might do more harm than good. Again, I cannot find these in the Vista system. Any clues to this thorny problem. I'd love to use a restore point, but, alas, the XP and Vista seem to wipe out each others images (?).

Is it possible to go back into the Vista from the XP and change anything that way around that would allow the logon to proceed in Vista without compromising the XP part of the system?

Constructive thoughts welcome please. Thank you in advance.

Hello sortofsmart, and welcome to Vista Forums. :)

If you like, you could try deleting all SID keys for only the affected user account to have it's profile recreated, and hopefully work afterwards.

If not, then you could see if doing a system restore at boot using a restore point dated before this issue may help.
 
Thank you for the tips Brink. I will think them through and see what is possible. :geek:

Any other contributions for this problem from dual boots users are also welcome.

Bye for now.
