What Is Service Host In Task Manager

A Service Host process (Svchost.exe) loads DLL files as services. Groups of services run inside the Service Host Process, with each group running in its own instance. Windows requires a number of services to function properly, which is why svchost.exe is typically running in many instances.

Service Host: Remote Procedure Call

Service Host: Remote Procedure Call appears in Task Manager, representing the service running inside svchost.exe, which is a shared host process. This service is vital to Windows’ smooth functioning.

System Using High Cpu

There are often hardware driver issues (bugs, old versions, incompatibilities, etc.) that cause high CPU consumption by the “System” process.

Services are prepared into logical teams that are all slightly related. Also, a sole Service Host illustration is established to host each group. For instance, one Service Host process works the three services related to the firewall. Another Service Host process might run all the services related to an individual interface, and so forth. Within the image below, for instance, you can view any particular one Service Host process works several related network services. Though another works services related to remote method calls.

This literally started today for no reason. I went to check on MSI Afterburner and the CPU temp was unusually a bit higher. I thought it was a memory leak but the ram looks good. CPU used to be around 31-33c and now its an 50c. The weird thing is that as soon as i use the PC the usage drops. I know that the temp isn’t high enough to cause damage but i feel uncomfortable having it at 50c idle when im doing nothing. I’ve tried restarting the PC and it doesn’t seem to fix the issue, i have a feeling it has to do with windows cause during gaming, temps are perfectly normal like they used to be. I just cant seem to spot the problem as the temps are fine when im using the PC. Im almost certain i have no virus or a miner or some shit cause i haven’t downloaded anything from chrome in weeks.

I think COM Surrogate task is broken. Most of the time, my CPU is at 99%.

This post will outline the 3 best solutions to fix the service host remote procedure call virus without complications when it causes a Remote Protocol Call high CPU error.

You must have TiWorker.exe enabled on your Windows PC in order for Windows Update to work properly.

Software communication protocols such as Remote Procedure Call allow programs to request service from programs on other computers on networks without having to worry about network details. A procedure call can be called a function call or subroutine call on a remote system, just as it would on a local system.

I have tried the following solutions according to Fix: Remote Procedure Call High CPU Usage –

Here are some common causes and remedies for CPU and hard disk load problems associated with remote procedure calls.

What causes high CPU and hard disk load in remote procedure calls?

Service Host: Windows Update High Disk Usage

You can observe how much disk, CPU, or memory are being used by specific items by expanding the Service Host: Local System.

Service Host: Windows Event Log

Event Viewer can cause excessive CPU or memory usage if there are large log files. You can solve this by deleting the log files. 

Several users have been able to resolve the problem by disabling Windows Defender, the antivirus program that may be responsible for the problem. Remote Procedure Calls tend to put a lot of pressure on your computer or hard drive when they are used by specific programs.

Service Host Local System Network Restricted

Delivery optimization is used by Windows update to improve processes. However, when it becomes stuck in operation, Service Host’s CPU usage will be high. When this happens, you may find that turning off delivery optimization resolves the issue. The speed and, particularly, the optimization of Windows updates may be affected, but removing the high CPU usage is a fair trade-off.

In addition, I’ve had a problem with svchost.exe consuming 100% of my CPU. The services in question were NLASvc, LanmanWorkstation, Dnscache, and CryptSvc. Firefox was the cause of my problem. As a result of the plugin-container.exe being added to Firefox in the latest version, Firefox and your browsing session won’t crash if a plugin crashes. My system was unbearable to surf as a result, but it made it hard to use it.

When Windows searches for updates, a Remote Procedure Call is used. In spite of the fact that Windows Update has successfully installed the updates found, it still searches for other updates, causing the service node to take a high CPU load.
