What is Winlogon.exe
Winlogon is a process that is responsible for logging in and out of Windows. With the help of the Winlogon.exe file, many hackers successfully disguise trojan viruses.
So, the process “Winlogon.exe” or “Windows Logon Application” is a system component that has an extensive functional set for working with a user account.
The structure of this component and all its powers have a rather complicated structure, to understand the wilds of which simply does not make sense. To understand its importance, you can simplify the list of his cases as much as possible and select the following items from them:
- Responsible for the safety of the desktop. Roughly speaking, every time a user sees a message about the need to enter a password to log into his account, this is precisely the evidence of the success of the “Winlogon.”
- Monitoring the integrity and security of user data, “collaborating” with the standard “SAS.”
- Monitoring the activity of network connections.
- Validation of the use of the operating system version.
- Ensuring proper functioning of screensavers (with active modes of operation).
Given the importance of this functionality, it should be noted, and also taking into account that the executable file of the process under consideration is located in the system directory – C: \ Windows \ System32, its unauthorized deactivation may lead to short-term or long-term disruptions in the operation of the operating system.
Therefore, if you have witnessed that in “Task Manager” in “Winlogon.exe” or in “Windows Logon Program” (this may be its name), the indicators of the created load are highlighted in red, in no case can you complete it yourself work until the reasons for this are clarified.
How does the WINLOGON.EXE error work?
WINLOGON.EXE infections install your executable on the marked PC in a very secret way.
They copy their loads into the Windows system folders and change the logs simultaneously so that this file runs automatically every time the system boots.
WINLOGON.EXE will modify the subkey named as HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run to get initialized at PC startup.
Once it is established, it also connects the workstation to a remote host in order to perform unpleasant tasks such as:
- for arbitrary downloads of harmful files in Backdoor
- to receive coded instructions from your developer
- to get the secret configuration
- to transfer cheated data on the infected PC to the remote server
Some common error messages
- “WINLOGON.EXE application error.”
- “WINLOGON.EXE is not a valid Win32 application.”
- “WINLOGON.EXE. This program is not responding.
- “Error Starting Program: WINLOGON.EXE.”
- “Application path failed: WINLOGON.EXE.”
- “WINLOGON.EXE failed.”
How WINLOGON.EXE gets inside the PC?
Cyber criminals use multiple means to drive WINLOGON.EXE on the target PC.
It could come through malicious website hyperlinks, grouping, social engineering spam, peer-to-peer file sharing networks, email attachments and so on.
It has the ability to exploit PC security vulnerabilities and be installed secretly without your knowledge.
Another easy way is to attach the burden with spam e-mail campaigns, and cyber-criminals do this a lot.
Such spam emails are designed very cunningly with fake header information giving an impression that mail is coming from some governmental organization, shipping company and so on.
Usually, these emails have so much grammar and misspellings.
At some point, cyber-criminals also promote WINLOGON.EXE as useful software or a necessary Windows system file.
For example, you may notice a fake message asking you to update Java or Adobe Flash Player files, and so on.
Problems and Damage Caused by WINLOGON.EXE
First, understand that WINLOGON.EXE is not an unattended infection and instead is bound to bring in so many other malware infections by exploiting the security breaches.
Thus, you will face several online as well as offline performance issues simultaneously and commits to the security of personal data as well.
Some of the common problems you may notice are:
- Shows false alerts claiming that your PC is infected with malware
- Prompts victims to click on unpleasant notification hyperlinks to fix problems
- Redirects the website about sponsored dangerous sites
- Blocks access to multiple legitimate programs
- Automatically turns off important processes and records
Most dll files are useful, and they are responsible for smoothly performing predefined functions.
However, there are malicious programs including malware and browser hijackers that are made of dll files like WINLOGON.EXE and change important PC settings unnecessarily.
They even allow cyber-criminals to gain access to their workstation.
Examples of Winlogon.exe errors and their solutions Note
In 99% of all possible errors with the Winlogon process are associated with viruses (1% human factor).
Since the vulnerability of Winlogon.exe is great, and the consequences can be significant, we will consider possible Winlogon errors and ways to deal with them.
Since all the errors described below are caused by the activity of viruses, before solving the problem, it is necessary to completely clean all partitions and disks from viruses.
It is best to connect the drive to another computer or boot from under another system to clean the infected disk from viruses.
# Error 1: Could not find the component
Solution: In the error text itself – sfc_os.dll was not found. Solution: The problem is uniquely in Winlogon.exe damage and the sfc_os.dll library. Over these files tried viruses, then we will recover. Clean viruses, then restore Winlogon.exe and sfc_os.dll. With a boot disk.
Everything now the system should work without a Winlogon obsessive error. There is a possibility that my Winlogon files will not work for you. Then the error will not disappear and you will have to copy them from the Windows installation disk.
# Error 2: Winlogon.exe application error memory cannot be read
Solution: A fairly common problem. Since there is no universal way to solve the problem, I will sign for everything known to me. Before use, you must check your computer for viruses.
Step 1. Open the Start menu – Run and type the sfc / scannow command. This is the integrity check and recovery of Windows system files. In order for the check to pass correctly, you need to insert a Windows boot disk into the drive. In case of errors, the files will be replaced.
Step 2. If checking the integrity of files did not help, then you can use the autoruns program ( you will find it on request in Google, I will write a review of this program later ) The program has a tab Winlogon, through which you can check all the files associated with this process. All empty and incorrect * .dll files (with questions for example) will need to be replaced. By the way, this method, though not always, but helps in most cases when an error occurs.
Step 3. Method 3 is similar to solving the 1st error. You can load the system via the LiveCD, clean viruses and replace the Winlogon.exe.
By the way, errors like memory cannot be read or written is not always caused by viruses. And this error is not always associated with the Winlogon.exe process.
How to remove the WINLOGON.EXE file from the PC?
- Open the command prompt window: Press the “Start” button on the taskbar and go to “Run” to start the “run” tool. Type the “cmd” command on it and press the “OK” button.
- Locate the dll files: Once the command prompt window opens, you have to find the exact path as mentioned in the image below. Type “CD” to change the current directory, press the space button, enter the path of the dlll file and press Enter. Use the “dir” command if you want to display the content on the screen.
- Unregister the unwanted dll: After locating the directory where you want to uninstall the dll, type “regsvr32 / u [DLL_NAME]” and press the Enter button.
- Unsuccessful unsubscription: Once the target dll files get unregistered, a conformation message appears on the screen.
Conclusion
Winlogon.exe is a system program that is responsible for the system boot and user authentication.
In the list of running processes, it should be in a single copy. Otherwise, you need to check your computer for viruses.
