The User Profile Service failed the logon. User profile
cannot be loaded
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"
Possible causes:
1.
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.
2.
This can also be a issue with the user profile entering into a
backup state.
3.
Manually renaming the C:\Users\(User Name) folder.
To resolve this problem
yourself, follow these steps:
1.
Delete the profile by using the Computer Properties dialog box. To
do this, follow these steps:
o
Click Start, right-click Computer, and
then click Properties.
o
Click Change settings.
o
In the System Properties dialog box, click the Advanced tab.
o
Under User Profiles, click Settings.
o
In the User Profiles dialog box, select the
profile that you want to delete, click Delete, and then click OK.
2.
Click Start, type regedit in the Start search box,
and then press ENTER.
3.
Locate and then expand the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
4.
Right-click the SID that you want to remove, and then click Delete.
5.
Log on to the computer and create a new profile.
If you tried to log on to
Windows and received an error message telling you that your user profile might
be corrupted, you can try to repair it. You will need to create a new profile,
and then copy the files from the existing profile to the new one.
