I have the same problem except mine occurred after I decided to add a
'Visitor' account. I have several people coming for Christmas and some of
them are bound to want to use the PC to access the internet and their emails
etc.

I have added a new user called 'Visitor' but when I try to login into the
newly set up account I get the message 'The User Profile Service service
failed this logon', I have checked the registry re
HKLM\Software\Microsoft\Windows NT\Current
User\ProfileList\ and was unable to find the new user listed there.

I certainly don't want to restore my PC to when I purchased it so can anyone
help, PLEASE!!!!
