Good day, I run a laptop computer with a German Windows 7 32 bit Home Premium, one local admin account and one local user account without admin rights. Everything worked fine for some month. Last weekend, after an automatic Windows update, the local user can't log on no more. System tries to logon for a few secs and than returns to family logon screen. I tried several things including roll back to a prior save point but to no avail. Other findings on the net suggest that this problem occurred also at XP some times. The solution suggested doesn't apply to Windows 7 though. If I "promote" the local user account to admin, the login works just fine. After "degradation" to restricted user account, login don't work no more. If I create a new restricted local user account, it can't log on either. New created admins work just fine. I assume, there must be a minor problem. Maybe a registry key to delete manually or something. I'd prefer a quick hack rather than to "overhaul" the complete system. Other than this prob everything works just fine. Of course I could promote the restricted account to admin level and hope UAC will prevent problems in times to come. Before I do that --> Has anyone a smart hint on hand? I deal with various Windows releases since Windows 1.0 but I never ran into this one before. Your comments and suggestions are highly appreciated.

Hi, We usually come across such scenarios: a) If after installing updates the security for certain programs get enhanced and it doesn’t allow you to log-in to the user accounts which doesn’t have administrative rights. As a result it will log you off from the user account when you try to log-in to the account. b) Also, it sometimes cause due to virus and malware. Let’s try these steps and check if it helps. Method 1 Boot the computer into safe mode and check if you are able to log-in to the standard user accounts. Safe mode will start Windows Vista with a limited set of files and drivers. Startup programs does not run in safe mode, and only the basic drivers needed to start Windows are installed, follow the steps to boot the computer in safe mode with networking: i. Restart the computer. ii. Start tapping F8 key. iii. You will get advanced boot option window. iv. Select the option “Safe mode”.
