Vista Profile Service

A post that may be of use to someone on the internet:
Currently I am working on a Dell Inspiron 1501 laptop with Vista. Scrolling through the event viewer while in Safe Mode, it appears that the User Profile could not be loaded so it loaded a temporary profile. The next login, however, Vista was unable to load the user profile. In fact, it started throwing a
"The User Profile Service service failed the logon. The UserProfile failed to load."

The best fix is to use the System Restore. I restored the computer back to the lastest restore point, and the computer logs in normally. Complete instructions follow:

1. Turn on computer
2. Press F8 until you get a menu with System Recovery/Safe Mode/Safe Mode with...
3. Select Safe Mode
4. Login with the user account. This solution assumes you are able to login to your account through safe mode.
5. Start All Programs Accessories System Tools System Restore
6. Restore your computer to an earlier point. Your computer will reboot and you should be able to login now.
7. Success! Celebrate with a can of Mountain Dew or something...

Another option (basically the same as above but using a different means). I used the method above, but I presume that this approach will accomplish the same task.
1. Turn on computer
2. Press F8 until you get a menu with System Recovery/Safe Mode/Safe Mode with...
3. Select the System Recovery Mode
4. Login with an admin user account. This solution also assumes you are able to login.
5. A menu is displayed with a couple options:
a) You can try to automatically detect and fix any problems (this most likely will only help if you have driver issues during boot up).
b) Select System Recovery. <-
6. Restore your computer to an earlier point. Your computer will reboot and you should be able to login now.
7. Success! Celebrate with a can of Mountain Dew or something...

At last! I hope this post helps you in a time of trouble.
