The Windows Memory Diagnostic (WMD) is a built-in troubleshooting utility for Windows 10 and 11 designed to identify defects in your system's Random Access Memory (RAM). These hardware-level issues often manifest as random freezes, application crashes, or frequent Blue Screens of Death (BSOD), such as MEMORY_MANAGEMENT or PAGE_FAULT_IN_NONPAGED_AREA .
