Windows cannot log you on because your profile cannot be loaded

Log Name: Application
Source: Microsoft-Windows-User Profiles Service
Event ID: 1500
Level: Error
Description:
Windows cannot log you on because your profile cannot be loaded. Check that you are connected to the network, and that your network is functioning correctly.

Solution:

Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry

You only have to do these steps:
1- Logon with local admin profile. (or other account different that you want to use, but with admin privileges).

2- Back up all data in the current user's profile folder if the profile folder still exists, and then delete the profile folder. By default, the profile resides in the following location: %SystemDrive%\Users\UserName

3- Open regedit and go to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. Here you can see all SIDs of loaded profiles and probably you'll have some of them repeated but with .bak extensions.
4- So if you want to recover your profile, desktop icons, ect... you only have to delete the profile with no .bak extension and rename the other, deleting only the .bak extension of it:
Note SID is a placeholder for the security identifier (SID) of the user account that is experiencing the problem. The SID.bak subkey should contain a ProfileImagePath registry entry that points to the original profile folder of the user account that is experiencing the problem.

Ex: In Regedit (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList) I have:

SID-1292428093-343818398-2115-158554 (1º Delete this Key)
SID-1292428093-343818398-2115-158554.bak (2º Rename This Key to SID-1292428093-343818398-2115-158554).

4- Restart your computer or Logoff and Logon with the profile that you want to restore and that's all, your profile will be restored Perfectly.
