   First login to Windows with a working administrator account.(assuming this issue is with a domain account, if not logon to the machine using another account with administrative privilege).
2. Go to the run bottom and type regedit then press Ctrl+Shift+Enter simultaneously.
   Navigate to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
   as in the following screen shot.
   
   
   
3. There should be a multitude of Registry keys inside the ProfileList and search for two identical ones which are differentiated by the .bak extension (e.g. xxxxxx1234.bak & xxxxxx1234).
4. The Registry key with the .bak extension contains the user's actual profile while the one without the .bak contains the Temp profile.
5. Delete the Registry Key WITHOUT the .bak extension and rename the one with it to xxxxx1234 (without the .bak). Notice the fields on the right, there should be a value named RefCount, change the value to 0.
6. Restart your PC and login again.If all goes well, you should be logged on. :)
