Unfortunately, owners of pirated assemblies and Windows repacks quite often get an incomprehensible WerFault.exe service error. Not everyone knows what kind of service and process it is responsible for, presented in the "Task Manager" with the same executable file. And the appearance of persistent errors, albeit not critical to the system, over time begins to annoy the user indescribably. Meanwhile, there is nothing particularly complicated in understanding this process and eliminating the consequences of failures in its work.
WerFault.exe: what is this service?
The process itself in any modification of Windows is a system (if you do not take into account viruses that can mask under it). The service of the same name is responsible for handling critical system errors with the formation of a special report that can be sent to Microsoft to provide recommendations on how to troubleshoot applications that caused crashes.
However, if in official OS this service, in theory, works fine, then pirated copies when trying to send reports remain, so to speak, overboard. Therefore, a message is issued, for example, in Windows 7 “WerFault.exe. Application Error. " By a normal reboot, such a system failure is almost never resolved. But the saddest thing is that in official versions, such an error can appear quite often. And here you need to take action.
WerFault.exe: application error. What should I do to fix it first?
To begin, consider the simplest troubleshooting method recommended by all users without exception. Error messages of this type can be associated only with the fact that the system has not installed the latest updates or requires cleaning the system of computer debris.
But in this situation, the WerFault.exe service is directly involved. What is this process in terms of reporting? As already understood, he analyzes the failures, but the question of sending a report remains with the user himself (during normal operation, it is proposed to send a description of the problem to Microsoft). But back to the correction.
The WerFault.exe Windows 7 error in the simplest case is eliminated by manually searching for available updates in the "Update Center" with their subsequent installation.
As an additional solution, many advise using optimizer programs (say, CCleaner, ASC, etc.), with which it is desirable to clean the system of unnecessary files in the form of ordinary computer garbage (program remnants after deletion, incorrect shortcuts, etc. .)
Finding out the causes of the failure and fixing it
If the failure appears after the optimization of the system, it will be necessary to find out whether the system processes are guilty of this or whether third-party applications, including viruses, are to blame.
First you need to use the standard "Task Manager", which simply terminates the WerFault.exe executable process itself, and then reboots.
If the failure manifests itself again, we use the system configuration section (msconfig in the "Run" menu) and instead of the usual start of the operating system, install a diagnostic start, and then perform a complete reboot. In this case, the user gets a “clean” Windows when booting, which includes only basic services. If the error appears again, we proceed to the cardinal methods of correcting the situation.
In this case, we are talking about the fact that some system libraries and files could be damaged, for example, as a result of a short-term third-party failure, exposure to malicious codes, or something else. First, we use an anti-virus scanner (for example, Dr. Web CureIt!), And additionally check the system with the AdwCleaner tool. This will help identify viruses and adware spyware.
If scanning the results did not give, apparently, it is just the damage to system components that are vital for the correct functioning of the OS itself. You can check them for integrity and restore them through the command line (cmd) launched on behalf of the administrator, in which the only line is written - sfc / scannow. Then it remains only to wait for the completion of testing and recovery, after which, in theory, the appearance of errors associated with this service will not bother you anymore.
Finally
This is, in short, the WerFault.exe service. What kind of system tool is, I think, is already clear. However, no questions should arise regarding the elimination of its errors. The standard tool for scanning system objects helps almost always and can be applied not only in cases applicable to this situation, but also in the case of solving many other problems associated with violations in the operation of Windows system components.
