Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Service groups are identified at the following Registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\SvchostĮach value under this key represents a separate Svchost group and appears as a separate instance when you are viewing active processes. Services will be grouped like in previous versions of Windows. If your PC has less than 3.5 GB of RAM, the classic service management model will be used.
Increase security: Process isolation and individual permission sets for services will increase security. Now it is easy to find out which service is giving issues and diagnose it. Reduce servicing costs: Following reports of instability, service engineers, IT admins, and Microsoft engineers can rapidly pinpoint issues related to the exact service and fix it. You can use the Processes tab or the Details tab to see Memory, CPU, Disk and Network usage per service easily. 
Increased Transparency: the user can clearly see system resource usage for each service. Even if the host svchost.exe process is terminated, other instances and their services will continue to work. Increased reliability: If one service crashes, it won't affect other services or the host svchost.exe process. The new service model has the following advantages: So don't be surprised to see 60+ instances of the svchost process in Task Manager. So, if a PC has 3.5+ GB of RAM installed, svchost won't group services any more. This increases the number of Svchost.exe processes dramatically.Īccording to Microsoft, the memory-saving advantage of service hosts has diminished thanks to increased RAM size in modern devices. Now, for every service there is a dedicated svchost.exe process. Starting with Windows 10 build 14942, services are no longer grouped if your PC has sufficient amount of memory. Why So Many Svchost.exe Processes are Running in Windows 10 Creators Update However, in Windows 10 Creators Update this service grouping model was changed. 
According to Microsoft, this model of service management allows reducing the memory consumption and reduces attack surface. Each instance contains one or more services, i.e. This is because the Svchost.exe executable file is used to run various system services. Even previous versions of the operating system like Windows 7 and Windows 8 had a large number of them. Advertisement Windows is known for having a lot of svchost.exe processes.
