Error window

In this case, the PC user immediately has anxious thoughts about losing all data on the computer or about a virus attack on the system. But there is no need to panic, since this problem can be solved and you will not have to take your computer to a service center.

Cause of Profile Service Error

The most common cause is incorrect system registry settings. Another reason may be that the antivirus scan of your computer coincides with your login. In any case, the problem can be fixed.

Error resolution methods

So, you see a message on the screen that The User Profile Service is preventing you from logging in. What to do when I encounter such a message and how to solve this problem? There is a simple but reliable way. But first, try restarting your computer normally, the error may go away on its own.

If rebooting does not help, you should log in as an administrator. To do this, you will have to restart your computer and log in. Next, you should launch the Registry Editor. To start you need to click on the menu “ Start" to the program " Execute", which is located in the "Standard" section or launch it by pressing the keys Win+R. On the command line you should write “ regedit" without quotes and click OK.

Command to enter the system registry editor

The registry editor will open, in which you need to go through the folders in the left column in this order:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

  • Select a folder with a long name that ends in ".bak".
  • Find a file called " ProfileImagePath" - on the right, the name of your account and the path in it in the Users folder must be correctly indicated.
  • If the name is correct, then go to another folder with a long name and look for the same file. Most likely, it will be written here “ C:\Users\TEMP"or there will be a set of random characters.
  • We change the names of folders with long names. The one that ended in “.bak” is left without this ending, and the one that did not have this ending is renamed to “.bak” at the end. That is, we swap the ending “.bak” for the folders.
  • Now in the folder without ".bak" at the end, find the file " RefCount", then right-click on it and select the command " Change" And then enter the value “ 0 ».
  • Do the same in the file " State" Also enter a null value.

Renaming profile values ​​in the registry

All that remains is to restart your computer, and the problem should be resolved if you did everything correctly. The profile service should no longer prevent you from logging in.

If the method described above did not help, then by booting into, you can create a new profile and log into windows under it.

Also, do not forget about system recovery, which can be launched through the same safe mode and roll back the system to a date when the “User Profile Service is preventing you from logging in” error did not exist.

Hello everyone, today I’ll tell you how to solve the error User Profile Service prevents login in Windows 7.

When you log in to Windows 7, if you see a message that the User Profile Service is preventing you from logging in, it's usually because you tried to sign in with a temporary user profile and it failed.

User Profile Service is interfering with the system, unable to load it

In this manual, I will describe steps that will help fix the error “The user profile cannot be loaded” in Windows 7. Please note that the message “Logged in with a temporary profile" can be corrected in exactly the same ways (but there are nuances that will be described at the end articles). This is what it looks like.

Solving the error using Registry Editor

In order to fix the profile service error in Windows 7, you first need to log in with Administrator rights. The easiest option for this purpose is to boot the computer in safe mode and use the built-in Administrator account in Windows 7.

After that, launch the registry editor (press the Win + R keys on your keyboard, enter in the “Run” window regedit and press Enter).

In the Registry Editor, go to the section (the folders on the left are Windows registry keys) HKEY_LOCAL_MACHINE\ Software \Microsoft \Windows NT \CurrentVersion \ProfileList\ and expand this section.

Then do the following in order:


Ready. Now close the Registry Editor, restart your computer and check if the error when logging into Windows has been fixed: most likely, you will not see any messages about the Profile Service interfering with anything.

Solving the problem using system restore

One of the quick ways to fix an error that has arisen, which, however, does not always work, is to use Windows 7 system recovery. The procedure is as follows:


Once the recovery is complete, restart your computer and check if the message that there are problems logging in and the profile cannot be loaded reappears.

This is how you solve the User Profile Service prevents you from logging in error in Windows 7.

User account corruption is a common Windows problem. The problem occurs when you enter a password or PIN on the lock screen and when you press enter you get the error "User Profile Service failed to sign in. The user profile could not be loaded" in Windows 10 or User Profile Service is preventing you from signing in in Windows 7. .

Solving the "User Profile Service could not log on" problem using Registry Editor

Option 1: Correct the user account profile

Sometimes your account may be damaged and this prevents you from accessing files in Windows 10. Let's go to the registry editor in several ways, through safe mode:

Step 1. Press the keyboard shortcut " windows + R" to call the command "run" and enter the command regedit to enter the registry.

Step 2. In the window that opens, follow the path:

Step 3. You will have several keys in the parameter s-1-5. You will need to select the longest key with a long array of numbers and your account that has the "User Profile Service failed to login" error. Make sure that the path is correct, click on the long key and there should be a name in the right column, if you haven’t found it, then scroll through all the long keys until you come across in the right column your broken profile, in my case an account .

Step 4. If you incorrectly renamed the user profile folder C:\User\site of the affected account, then open Explorer along the path C:\User\site and right-click on the broken profile, select rename and manually enter the correct profile name (site). After renaming, go back to the folder in the registry and make sure that the name is written as in the picture (step 3) C:\User\site.

See two options, step 6 and step 7, depending on who you are

Step 5. Now we will make two options, if we have one long key S-1-5-21-19949....-1001. bak(extension .bak at the end) and with the second without .bak those. just S-1-5-21-19949....-1001. Depending on who has two or one profile lined up.

Step 6. There is only one key at the end of s.bak (S-1-5-21-19949....-1001.bak).

  • A) If you only have one key at the end with .bak(S-1-5-21-19949....-1001.bak), right-click on it and click rename. (see picture below).

  • B) Delete the word itself with a dot .bak so that you get just numbers. Continue with step 8. (see picture below)

Step 7. If you have two identical keys, one without .bak, the second with .bak. (S-1-5-21-19949....-1001 and S-1-5-21-19949....-1001.bak) .

  • A) In the left pane of the registry, right-click on the key without .bak and add a period, two letters .bk(see picture below).

  • B) Now right-click on the key with .bak, select rename and delete .bak with a dot. (see picture below).

  • B) Now go back and rename the first key with .bk V .bak. Press enter and continue with step 8.

Step 8. Select the key that you renamed without .bak and from the right in the column, double-click to open the parameter settings, and assign the value 0. If you do not have such a parameter, then right-click on the empty field with the right mouse button and create a DWORD (32-bit) parameter, rename it RefCount and set the value to 0.

Step 9. In the right field, select the key without .bak and in the parameter State set the value to 0. If there is no such parameter, then click on the empty field to the right and click create DWORD (32-bit), rename it to State and set the value to 0.

Step 10. Restart your computer and the “User Profile Service failed to log in” and “Unable to load user profile” errors in Windows 10 should disappear.

Option 2: Delete and create a new user profile for the account

This option will delete your user profile, causing you to lose all of your account settings and personalization.

Step 1. If there is another administrator account that does not have an error, log out of the current account (eg: site) and log into the administrator account.

If you don't have another admin account to log in to, you can do one of the following options below to enable the built-in admin account to log in to and proceed to step 2 below.

  • A). Boot into Safe Mode, enable the built-in Administrator, log out and log in to Administrator.
  • B). Open a command prompt window at boot, enable the built-in administrator, restart your computer, and log in to Administrator.

Step 2. Back up anything you don't want to lose in the C:\Users\(username) profile folder (eg: website) of the corresponding user account to another location. When done, delete the C:\Users\(username) folder.

Step 3. Press the windows + R buttons to open the Run dialog box, type regedit and click OK.

Step 4. In Registry Editor, navigate to the location below.

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Step 5. In the left panel in the ProfileList, click on the long key that has an account error. The profile is visible on the right.

Step 6. Delete error profiles with.bak and without.bak. Eg ( S-1-5-21-19949....-1001 and S-1-5-21-19949....-1001.bak)-delete.

Step 7. Close Registry Editor and restart your computer, after which it will automatically recreate the new user.

Let's solve the problem "Unable to load user profile" in a simple way

Method 1. This method does not work for everyone, but it has helped many. Try to copy your documents in the folder (C:\Users\) to another location to create a backup just in case. Typically the problem occurs due to corruption of the "NTUSER.DAT" file located in the "C:\Users\Default" folder. To solve this problem you need to replace the "NTUSER.DAT" file with another profile. .

  1. Log in to the system in safe mode with a profile account that works.
  2. Find the file (C:\Users\Default) "NTUSER.DAT" and rename the .DAT extension to .OLD. It should be (NTUSER.OLD).
  3. Find the file "NTUSER.DAT" in the work profile such as "Guest", "General". Example (C:\Users\Guest\NTUSER.DAT).
  4. Copy it and paste it into the default folder C:\Users\Default.
  5. To restart a computer.

You can copy this file from another computer with the same version of windows and paste it to your home along the path C:\Users\Default.

Method 2. You can try replacing the entire “C:\Users\” folder from another computer.

  • Take a flash drive in FAT32 format and write the C:\Users\ folder onto it from another computer and transfer it to your computer.

If anyone knows how else to fix the error, “The User Profile Service prevents you from logging in” using another method, then write in the “report a bug” form.

Just recently we encountered another problem. The problem appeared with our former client for whom we collected terminal server based on Windows Server 2008 R2, she is quite famous if she writes that User Profile Service prevents login, it means that there are obviously problems with the profile itself, this could be a non-working profile folder (damaged userdata files, etc.), as well as problems with security settings, namely user access to this folder or system service access to the profile folder. We solved this problem many times; sometimes we had to completely recreate the account from scratch, transferring all data, documents, settings, which usually took a lot of time.

When logging into the terminal server, this error appeared " unable to load user profile", naturally, the first thing to do was rename the user’s folder, try to create a clean folder with all possible access rights, but all efforts were in vain and, quite by accident, looking through the registry we discovered the following:

To begin with, about the registry section in which the problem was discovered on the server, it is located in this path:

KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Pay attention to the highlighted lines, this is the user account that was not able to be logged into from another computer. Immediately realizing that the profile folder refers to temp, it was decided to do this:

Simply by renaming the line from 1005.bak we returned the account to a working state. However, there were no further problems with this account.

Why is this happening

We decided to look for a report on this question on the Internet and came across an interesting article on the website support.microsoft.com: which says “This error can occur if the folder with the user profile was deleted manually. When deleting the folder with the profile manually, the security identifier (SID ) is not removed from the list of profiles in the registry." However, the client's problem arose on its own, and It seems that you should not believe everything that is written on the Microsoft website, this problem, in our opinion, could have occurred as a result of a failure of equipment or software code that they themselves wrote, of course no one will talk about this. According to recent observations, the problem cannot be resolved without rebooting the server, perhaps some program, service blocks or uses files in the user’s folder, and therefore he cannot get into the account, and then his user is renamed to bak and he logs in under the same ID to the temp folder!

Sometimes it may fail that after a new account has been created in the OS, the PC user cannot log into the system from it. This directly depends on the fact that Windows has a user profile service, due to an error in which nothing works. Read on - the suggested options will help you fix the problem.


What's the first thing you can do if the User Profile Service is preventing you from logging into Windows 7? Restart your PC and before loading Windows OS itself, click F8 to go to the menu BIOS. Afterwards, select to start the OS in Safe Mode , then let the download take place.


Now open the menu Start (checkbox) and in the search bar below type User Accounts – select the appropriate line as below:



Accordingly, let's move on to Manage another account . After clicking in a new window, find the line by Create a new account – create and specify account parameters:



The next step you will need to go to is Local disk with OS Windows - I have this "WITH", and for almost all users too. Enter the folder Users (may be called Users). You now need to define a couple of folders: the folder of the user who does not want to boot, and the folder of the user who has just been created. Go to the folder of the non-booting user and copy all the data to the newly created one.



Restart your PC and log in to the user account where you copied all the data. If the account starts, great - now you have a new account. an entry with a new name (if you want, you can delete the old one later).


If this solution did not help you, the following should definitely help you.


Similarly, we go to Safe mode from the administrative account records. We start in the same way with Start , but in the search line we indicate regedit:


We launch the registry editing program and now we have a very long way to go! Be careful! We start with a folder called HKEY_LOCAL_MACHINE- and from there we will go through the branches of folders.


HKEY_LOCAL_MACHINE– start with it – see the screenshot:



After that SOFTWARE , Now Microsoft , V Windows NT , from her to CurrentVersion and now we already find ProfileList .


Inside ProfileList in addition to the rest there will be two almost identical folders, only at the end of the other one will be added .bak- this is the account that does not let you through.



First, let's deal with the folder without .bak- just rename it, giving it some name so that ProfileList it was not repeated with any other. And the folder with .bak at the end we just delete this extension - in the end it will acquire the name of the folder with which you dealt with first - only numbers will remain.


If you followed the description, after rebooting the PC everything should work fine. Please let me know if you were able to resolve the issue where the User Profile Service prevents you from logging in. What can't I do in the OS? What was difficult?
