the user profile service service failed the logon
User Profile Service service failed the logon. User profile cannot be loaded
how to solve problem the user profile service service failed the logon
i just met this problem tomorrow, when i try to login into my windows 7 ultimate edition.
i find this solution in internet
1. Use other profil with administrator privilege to login (if you dont have one then you should
look at this post http://caleudum.com/how-to-get-admin-privilege-in-windows/)
2. Open regedit
a) That the key name doesn’t end in “.bak” (remove .bak if there)
b) That the RefCount value is 0 (change it if different)
c) That the State value is 0 (change if different)
for my problem the solution is the a)
i found out that my profile is ended with .bak, like in the picture above
after i rename this by removing the “.bak” i can login with my account that is failed the logon before
3. log off and try to log in with your own user account
hope it can help you.
