Fix "The User Profile Service failed the logon. User profile cannot be loaded." Error in Windows 7

A user profile is a collection of settings that make the computer look and work the way you want it to for a user account. It contains the account's settings for desktop backgrounds, screen savers, pointer preferences, sound settings, and other features. User profiles ensure that your personal preferences are used whenever you sign in to Windows.

A user profile is different from a user account, which you use to sign in to Windows. Each user account has at least one user profile associated with it.

This tutorial will show you how to fix when you log on to Windows 7 using a temporary profile, and get the following error message:

The User Profile Service failed the logon. User profile cannot be loaded.
