Issue: How to fix “System call failed” error in Windows 10?

Hello all. Could someone please explain to me why explorer.exe keeps crashing with an error “System call failed?” It all started the next after I installed Windows 10 April Update. Thanks for any help.

Solved Answer

“System call failed” is a pop-up error generated by Windows OS when the Explorer.exe[1] process encounters a problem. Explorer.exe or Windows Explorer File is one of the core Windows OS parts, so it's practically impossible for Windows to run smoothly without it.

Typically, it's located in C:\\Windows directory. It's responsible for the interconnection of folders and files via the graphical user interface. It's hardly possible not to notice Explorer.exe crashes and freezes. When this executable malfunctions, the PC gets stuck, programs unresponsive, all content stored on the desktop may disappear and then reappear after a while.

The “System call failed” error is directly related to explorer.exe crashes. However, no single reason would explain why this is happening. For the most part, the problem occurs due to the pro-longed explorer.exe performance. Thus, restarting it should solve the problem. Nevertheless, the problem may be a bit deeper.

Experts claim that it's essential to draw once attention to the circumstances under which the “System call failed” error occurs. If, for instance, the problem emerged soon after the installation of Windows 10 April 2018 Update,[2] we would recommend you to install the latest cumulative or patch updates for Windows 10. If the problem can hardly be ignored, you can always use Previous Windows version feature or roll back the update.

Nevertheless, the update or upgrade is a seldom cause of the Explorer.exe “System call failed” error on Windows 10. It may be triggered by some third-party software or virus, as well as a malfunction of system's files. Since there are many different reasons why this problem can occur, you should learn how to fix “System call failed” error by reading the rest of the article.
