How to fix a corrupt user profile in Windows 7 and Vista: The User Profile Service failed the logon

Create a new user profile

If you have a second account on your PC which you can log in to, you may be able to use this account to follow the steps below to create a new user account.

However, if there is no other account, boot into Safe Mode (as described above) and try to follow the steps. If that still doesn’t work, you need to enable the hidden admin account. To do this, type cmd in the search box and then right-click on Command Prompt in the list of results and choose Run as administrator.

Now type the following at the prompt:
net user administrator /active:yes

The response should be: The command completed successfully. Now reboot your PC and you should see an Administrator account as well as your corrupt account. Log into the admin account (there’s no password) and follow the steps below:

Step 1. Open Control Panel and click User Accounts and Family Safety (or similar). Click on User Accounts.

Step 2. Click Manage another account and type in the password (if prompted).

Step 3. Click Create a new account and type the name. This must be different from the account which is corrupt, but you can rename the account later on if you want to have the same name as before.

Step 4. Restart your PC.
