DescriptionWindows cannot load the users profile but has logged you on with the default profile for the system.

DETAIL - %1
Event InformationExplanation :
The system is unable to load any of the following: the users local user profile, the users roaming user profile, or a temporary profile. As a result, the system logged the user on with the system profile if the user is a member of the Administrators group.

Possible causes include: insufficient computer memory, low disk space, or corruption of the user profile and default profile, or the systems inability to access the system profile for security reasons such as incorrect permissions.

User Action :
To troubleshoot this problem, try one or all of the following:
Review the Event Viewer logs. Look for additional information and search for related profile (userenv) events. 
Ensure that you have sufficient computer memory and disk space. 
If the users profile registry hive(ntuser.dat) is corrupted, replace it with the backup copy of this file. 
Verify that permissions are set correctly on the users local profile folder. 
If this is also a roaming user profile, ensure that the correct permissions are set on the users roaming profile folders stored on the server.</p>
