NPFS_FILE_SYSTEM (0x00000025) Error: What is It and How to Fix It on Windows

Many readers have complained about getting the blue screen error NPFS_FILE_SYSTEM with error code 0x00000025. In this guide, we will discuss the error and its causes in detail, along with a few solutions to fix the problem.

What is NPFS_FILE_SYSTEM (0x00000025) error?

The NPFS_FILE_SYSTEM (0x00000025) error is a Blue Screen of Death (BSoD) error code on Windows operating systems. It indicates a problem with the Named Pipe File System (NPFS) driver, which handles named pipes, a method for inter-process communication (IPC) on Windows.

According to Microsoft Learn, the probable cause for the issue is the depletion of nonpaged pool memory. Nonpaged pool memory is a part of system memory used by the operating system and drivers that can be replaced with the disk, which makes it vital for system stability. The first step is to check Microsoft’s Troubleshoot blue screen page for a resolution of BSOD errors, then follow the steps given below.
