Win7 Logs In, Then Out Suddenly

GokAy said:

Nothing wrong with sfc, usual corruption which is actually not a corruption :)

Did you try uninstalling McAfee yet?

Not yet, will do that and let you know what happens. Could it honestly just be the AV software not letting me log into any account but the Mum's account?

There are actually a few problems in the CBS.log

Code:

Please download and save the CheckSUR tool from http://support.microsoft.com/kb/947821
(you'll need to look in the details for Windows 7, downloading from the Microsoft Download Center)

Run it - The tool can take anywhere from 5 mins to a couple of hours to run (or 'Install') depending on how much it has to do, and may exit silently - it may appear to freeze for most of that time, but be patient.
The result is logged in the C:\Windows\Logs\CBS\CheckSUR.log file - and an archive …\checksur.persist.log file

Then zip the CheckSUR.log and upload it to your reply.

I will attach my results as soon as it finishes installing. Thanks for your help with this!

McAfee can have many unforeseen side-effects.
Once you've uninstalled it, you must run their cleanup tool as well...
Download the McAfee removal tool from:

http://download.mcafee.com/products/...tches/MCPR.exe

Click Save, and save the file to a folder on your computer.
Navigate to the folder where you saved the file.
right-click on MCPR.exe and select 'Run as Administrator' to run the removal tool.

when complete, reboot.
After the reboot, open an Elevated Command Prompt, and run the following command

NETSH WINSOCK RESET

You'll be advised to reboot - do so.

Wow so a few things happened. First I updated the graphics driver (I thought this was causing the issue) - Successfully updated but still couldn't log on. Then I uninstalled McAfee and used the Removal tool you gave me Noel.

Also, sorry Noel but I ran CCleaner after the Windows Update you sent me and it deleted the log!

I restarted and Voila! I could log into both the Mum and Dad account fine and it wasn't logging out again, but this is only half of the problem fixed.

I still could not log into the Kid 1 and Kid 2 accounts.

I have noticed that Mum and Dad are both 'Administrator' accounts and the kids are 'Standard' accounts. What on earth is going on?

Thanks Guys

Maybe the Winlogon registry key permissions got broken?
- Open registry and browse to HKLM\Software\Microsoft\Windows NT\CurrentVersion
- Right click Winlogon and Permissions.
- See if Users group has Read rights. (System, Admins and TrusterInstaller are all Full Control).

1 Second, i'll try this now.

Yes i've just checked, the Users group does have Read rights and the other 3 have Full Control.

For the meantime i've changed the Kid accounts to 'Administrator' and I can access them so the problem is definitely to do with the 'Standard' User Accounts.

Any ideas?

Also check userinit permissions C:\Windows\System32\userinit.exe
Same users but all have "Read & Execute" and "Read" rights while TrustedInstaller is "Full Control".

Explorer.exe has same permissions, located under Windows.

Checked them both, all is fine.

Anything else I could try?

GokAy said:

It is certainly a permission/rights issue somewhere since same account logs in fine once given admin rights.

Can you try creating a new standard user account? Lets see if the issue persists with a new account.

Yes the issue still persists with this new account. So you're probably right saying its a permissions issue.
