Super problem this morning at the opening of a laptop, the user profile does not load automatically after updating to Vista. An error message comes indicate a failed logon service Service user profile. I had only just reinstall it over: what misery this OS.

What solution to this problem?

This is a Dell branded computer and consulting with various topics on web forums. This does not seem concerned that this manufacturer. This is the second time I encounter problems between Microsoft operating systems and the Dell brand. The first time, this concerned the activated processor e4300 dual core in the bios that was a black screen at startup.

To resolve this error, start your computer, press F8 repeatedly to obtain an menu with several options before the Vista logo appears.

1. OK boot in Safe Mode.
2. Vista is running everything is fine
3. Go to your C: \ Documents and Settings to see profiles
4. Save one that poses particular problems in autostart
5. We create a new profile in order not to cut the legs and security
6. Start Menu -> in the search field -> enter net user votrenom2 / add
7. Then remove the tool via the management of user accounts:
8. or right click Computer -> Properties -> Advanced tab -> User Profile
9. Finally reboot and you should see the two profiles
10. Just log on anyone who does not work, it should pass
11. Finally recopy your office saved

After checking at the Windows Update, it is a failed update that has generated this problem.
