{FIXED}: MsMpEng.exe On Windows 10 High Disk Usage Issue (2022)

The Antimalware Service Executable process (also known as MsMpEng.exe) plays an integral role in Windows Defender service. The process is responsible for allowing Windows Defender to monitor potential threats.

  • Its Full Scan feature slows down the entire system performance, and you may face lags, delays, and frequent hangs, while the CPU continues to occupy more resources than ever.
