Vista problem

[Tiz]

I've got a problem with my pc. Dell inspiron 631 running Vista Home Premium. When I tried to log on using the main user account I get the folowing message

"The User Profile Service failed the logon
User profile cannot be loaded"

Can anyone advise me how to remedy this?

Boot into safe mode.
(Restart your computer and as soon as it starts booting up again continuously tap F8. A menu should come up where you will be given the option to enter Safe Mode.)

Enable the hidden administrator account:
Start menu, right click on cmd and select 'Run as administrator'
In the command window type the following line:

Net user administrator /active:yes

logoff and back in again as administrator with the password you chose above

Before we proceed we need to backup your Registry. Do not ignore this step as making changes to your computers registry can be a dangerous proceedure. A backup will allow us to recover information if necessary.
The utility we're going to use, ERUNT, will make a complete backup of your registry including the Security hive and user related sections.

• Download and install ERUNT (Emergency Recovery Utility NT) from here or here
• Click on ERUNT and follow the prompts to backup your registry to a location of your choosing.

Click Start > Run & type Regedit. When regedit starts
Click on HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > ProfileList

You'll see a list of folders something like S-1-5-####. Two will have exactly the same name but one will have '.bak' at the end
Look in the right-hand pane of each folder for "ProfileImagePath", it should have the value, both cases, "C\:Users\LoginName", in my case it says "C\:Users\Roger". If that's the case, we can recover your profile

Right click on the .Bak and select "rename"; change the ".bak" to ".old". Then rename the other folder and add ".bak" at the end so that it now has the same name that the first one had originally.
'Finally, rename folder.new by removing the '.old' off the end.Press enter and close regedit.

Reboot and login your old account.
Run cmd (as administrator) again and type:

Net user administrator /active:no
