Windows 7: Can't log onto guest account

Can't log onto guest account

Lenovo G550
Windows 7 Professional
3 GB Ram

I enabled the "Guest" user for my son to use when he visits, but when he tries to log on as "Guest" the message: "The User Profile Service service failed the login" appears.

I disabled Guest and re-enabled, but still the same message.

I created a user name just for him as a standard user, but when he logs on as "Joe", the same thing happens. I created 4-5 other accounts, some standard users, some administrators, but can't log on to any of them.

I have no trouble logging on as myself (administrator).

After searching the forums I find similar issues in Vista, but not for Windows 7, and the registry entries seem to be different in Vista and I don't want to try the fixes in Windows 7.

When I go to C:\Users\ the other accounts I set up, are not listed, just mine.

Any suggestions?

See this tutorial on how to fix this problem. It'll work with win7 also.

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

1. Open an elevated command prompt, i.e command prompt run as an administrator. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

2. Now type the command sfc /scannow and press enter. The System File Checker will start checking the system.

This will resolve any corrupt files within the OS and *may* help resolve your issue. I would do this before tweaking with the registry. Also, please remember to perform a Backup of your files and create a System Restore point before tweaking your Registry!

Is W7 Guest Account the Safest Account to Use On the Web?
I've been plagued Trojans and re-directs lately with a W7 Standard Account which I thought and taught was the right choice for safer web browsing. Not as many system ports open to attack. So, if MS recommends the Standard Account over Administrator for safety reasons, is using the Guest...
