What Does the Shell Infrastructure Host Process Do on Windows? How to Fix Its High Resources Consumption
The Shell Infrastructure Host Process, also referred to as sihost.exe, is a core component of the Windows operating system. It is responsible for managing and maintaining the graphical user interface (GUI) components such as the Start menu, taskbar, and Action Center on Windows.
Whenever you interact with the GUI components on your Windows machine, sihost.exe kicks in to process your input and display the output on your screen. As a result, sihost.exe is constantly running in the background, but it should not consume a large amount of resources.
However, some users have reported that the Shell Infrastructure Host Process consumes a significant amount of system resources, such as CPU or memory, leading to sluggish performance and system instability.
If you notice that your Windows machine is running slow or freezing, it could be due to sihost.exe’s high resource consumption. Fortunately, there are several ways to fix this problem.
- Restart your machine
The first solution to try is restarting your computer. Sometimes, certain system processes cause resource consumption issues due to misconfigured settings or errors. Restarting your computer will terminate all processes, including sihost.exe, then reinitialize the system with fresh settings.
- Run a virus and malware scan
The next solution is to run a virus and malware scan. Sometimes, viruses or malware can infect your system and cause unwanted high resource consumption. Malicious programs can use processes like sihost.exe to hog system resources, and this causes slow performance. Therefore, scanning your system for malware and viruses is essential for optimal system performance.
- Check for Windows updates
If you have an outdated Windows version or missing important updates, your computer may freeze, and sihost.exe may cause resource consumption issues. Microsoft regularly releases updates that address such issues; therefore, checking and installing all updates is essential.
- Disable unnecessary services
The last solution is to disable unnecessary services, like the Windows Notification Service for third-party applications. Some third-party programs make heavy use of the Windows Notification Service, which may cause sihost.exe problems.
To disable the service, open the Task Manager by pressing (Ctrl + Shift + Esc) on your keyboard, select the Services tab, and locate the “Tile Data model server” service. Right-click on this service and choose “Properties.” From the General tab of the properties window, find the “Service status” section and click “Stop” to immediately stop the service.
