The DISM Host Servicing Process in Windows 10 is simply the Deployment Imaging Service and Management Tool (DISM.exe), a system process that is used for servicing and repairing Windows images, which includes the one used for system recovery. DISM is usually running in the background performing Windows Update tasks, system repairs or feature installs. It’s a legitimate Microsoft process, but if it’s using high CPU or memory for an extended period of time, it might be a sign that it’s stuck on an update, there’s something wrong with the system files, or in rare cases, it’s malware masquerading as dismhost.exe.
Understanding the DISM Host Servicing Process:
1. What is DISM?
- DISM, short for Deployment Image Servicing and Management, is a command-line tool used for servicing Windows images offline or while the operating system is running.
