Another common malfunction, only here users often become to blame - this is the user profile service that prevents logging in. The error indicates failures or bugs in the profile itself and it occurs due to a mismatch between the security key or the name of the folder location. Temporary profiles are extremely inconvenient, as they completely delete all data entered by the user during the session. This kind of malfunction must be rectified immediately.

First of all, remember, you may have changed any variables / folders / files that are system-wide for the user. If so, just put everything back in place and reboot the system. Another option is to install programs that block or edit profiles, such an application can be an antivirus with parental control.

Nevertheless, for a full-fledged solution of the situation, you need to figure out how to fix the error of a temporary user.

How to fix temporary profiles?

Almost always, a malfunction occurs due to a change in the name of the folder with user data. The system simply does not know where to store the profile information and therefore clears it at the end of the session. If you fundamentally want to change the folder name, for any reason, then you can:

1. Rename the user, and the folder name will change with it:

  • Click on the avatar in Start;

  • Select the "Change your account name" link.

2.This option helps both in the case of renaming and diagnosing a malfunction:

  • Search for regedit;
  • Follow HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList;
  • Among the folders with SID keys, find with the ending .bak;
  • The Profile Image Path parameter must contain the correct folder path, if it is not, change it;
  • Check for a similar section on the left, only the folder name without bak, and the rest is identical. If such exists, then remove it, and the one that contains bak should be renamed in such a way as to remove the ending.

This method can also help in solving our main problem.

Also, the error can be temporary and occur due to a one-time failure, so before moving on to alternative solutions, just restart your computer and check for a malfunction.

Eliminate Login Blocked

The "user profile system is preventing logon" error occurs due to mismatched security keys. They changed or deteriorated due to a bug in the system, when the key was created for one user, and entered for another. Such confusion arises in temporal profiles, in other words damaged ones.

The problem is located in the registry, respectively, and it will have to be dealt with from there:

  • In the search, set regedit;
  • Follow the path HKEY_LOCAL_MACHINE-> Software-> Microsoft-> ​​Windows NT-> CurrentVersion-> ProfileList;
  • The folder must contain several sections (depending on the number of accounts), which contain the S-1-5 name and then the SID key. Before you change anything, make sure that the right pane of the section contains a Profile Image Path with the path to the desired profile (so as not to harm another entry). A folder that without the ending bak and with an identical name can be deleted or simply changed its name;

  • Remove .bak from the section with the extension. To do this, right-click on it and click "Rename";
  • Now, on the right side of the renamed section, find the RefCount parameter. Right click on "Change" and replace the value with 0;

  • Likewise, set the State argument to 0;

  • Close the editor and restart the system.

Account replacement

Perhaps more time-consuming is the removal of the lagging profile and the creation of a new one. You just need to save the user information to another section first.

The easiest way to achieve this result is to log in using Safe Mode, which uses the built-in administrator profile, for this:

  • At the time of launch, press F8;
  • Set the selection to "Safe Mode", if necessary using network drivers;
  • Then follow the path C: WindowsProfile, where Profile is the name of the entry;
  • Download a copy of the folder to a drive other than the system drive.

You can also use the data migration utility and after the checks, simply select the data you want.

For a complete uninstallation of the profile, it is better to use the special Microsoft Fix it tool. It cleans up all repositories of profile information to eliminate the possibility of a problem returning. You can find it on the Microsoft website.

Now we need to create a record:

  • Open "Control Panel" from Start;
  • Find the "User Accounts" tile;
  • Click on the link "Manage another account";

  • At the bottom, click "Create an account";

  • After all, you need to copy the data previously saved to the user section.

An additional way to fix the error

The simplest and effective method Is to use the recovery service. There is only one serious limitation, namely: the presence of a point at the right time interval. You should find the point that was created with a working system. The tool we need can be found by entering "System Restore" in the search.

After completing the above algorithms, you can get rid of this error by changing installed key security or creating a new profile.
