Windows 7 - "The User Profile Service service failed the logon. Use

hello,
I have upgraded vista to win 7 home premium, everything was going great, until the network card stopped working, i used talktalk "talk and go" to reset the adaptor then the computer re-set and shut down.
i restarted but it wouldn't get to the log on page before shutting down.
I borrowed a laptop and found a thread to turn back the clock to vista with some command prompts, but this didn't work.
To compound things i then saw open in previous good something and the log on screen appeared - i thought YES, but NO..... typed in my password......"The User Profile Service service failed the logon. User profile cannot be loeaded". it appears that i have deleted my account...
i have looked at other threads of this nature and have been directed to a vista tutorial - however it staes that you must be logged on as an administrator - i can't log on!
i've tried opening the command prompt and turing on the in built administrator, but i have to restart to get back to log on page which defeats the command prompt.
i have tried to re-install Windows 7 but comp tells me i have started with disk in restart then insert disk. this does nothing...

i'm really really fed up at the mo i thought that win 7 would be better than this.....

any help to solve this would be great. thanks

Hello, and welcome to the forums.

Have you enabled "Boot from CD" in your BIOS?

for some reason Bios is blank.......just a flashing white cursor on a black screen in the top left hand side....

however a friend managed to get the system to re-install BUT only with custom, luckily i did a back up....

thanks for the reply, touch wood i'm back running again

can this threat be closed?

I have a very clean windows 7 system and hit this error yesterday... I was able to recover using a restore point.

I can't find anything on the web on the cause or if MS is going to address this... I hit this bug after I did a windows critical update two days ago. Has anyone figured this out?

I am just about ready to get a mac.

I just hit this same issue. Completely random, IMO. Have not been able to fix yet

i had this same problem last night and its due to a microsoft update that needs patching go to system restore and restore your system to before you installed the update

does anyone know how i can get to the restore settings options if i can't even get past the logon? it just keeps telling me that the user profile service service failed the logon. thanks

Come guys this too easy, go to
HKLM\Software\Microsoft\Windows NT\Current
User\ProfileList\ and was able to find the key for my user id SID. Rename the bak to .bk, then rename the identically one to .bak, then remove the old one that you named to .bk, by just deleting the .bk extension and on the old one then change the State property under my key to 0.

Windows 7, user profile will not log on

thanks for your reply fantom711, but i don't know anything about computers...how can i do what you've outlined if i can't even get past the logon? thanks

Do you have an option to change user? Look around on the login screen for something that says "Other Credentials"

Try logging in with the username "Administrator" and leave the password field blank.
