Issue: How to fix Device Setup Manager service (DsmSvc) high CPU in Windows?
Hello. I suddenly noticed that my PC (it's running Windows 10 version 22H2) has become very slow. So I opened Task Manager and found that Device Setup Manager service is using 50 – 80% of CPU. I don't think this is normal, although I am not sure what to do about this.
Solved Answer
Device Setup Manager service (also known as DsmSvc) is a Windows service responsible for managing device installation and setup. Its purpose is to ensure that devices are properly installed and configured on Windows. While being a basically mandatory system, it can sometimes cause high CPU usage, which can negatively impact the performance of your device.
High CPU usage can cause the computer to run slowly and may make it difficult to perform tasks such as opening programs or browsing various websites. There are several possible solutions to this issue, including disabling the DsmSvc service and running a system scan for malware. In some cases, reinstalling the operating system or upgrading to the latest version of Windows may be the only choice, unfortunately.
