Windows® 7 logon error
What are the causes of various types of Windows 7 logon errors? Read on to know the troubleshooting tips
Windows 7 is the latest and most advanced operating system from Microsoft. The OS has got extra features when compared to other operating systems. Windows 7 is also very user friendly. You have to install the genuine copy of the OS for the system and the drivers for the computer. Otherwise there might be issues. You need to manage all the programs which are installed on your computer. The time to boot your system would depend on how many start up items are there. These programs would automatically load when you boot your system. So in order to reduce the boot up time, you need to reduce the start up items.
The following are the different kinds of Windows 7 logon errors and the possible causes of these errors:
- "STOP 0xC000021A" error
- Booting error
- Causes of the errors
"STOP 0xC000021A" error
An error occurs when the process of the Winlogon.exe file fails. While Windows NT kernel detects that this process has stopped, it terminates the system and raises the "STOP 0xC000021A" error. Another logon error message would be due to the use of temporary profile. If the "Do not logon users with temporary profiles" Group Policy setting is configured, then "User profile service failed the logon" error might occur.
Due to the registry corruption, the Windows 7 operating system does not boot and displays an error message. Registry corruption occurs due to the system crash, malware attack and due to the improper shut down. Registry has an important role that keeps the references of all the software applications that you used in your system. So if the registry part has some problem, it might cause the logon error in the Windows 7 operating system.
The causes of logon error message would be due to mismatched system files. The error message might also be due to the backup program that is used to restore a hard disk which did not correctly restore files that might have been in use. The registry corruption would cause the logon error message in the operating system. If an incompatible third-party program has been installed, it can cause the error message.
