If you find some problems or difficulty opening the file, you need to update your programs and software to the latest version to avoid corrupted files.

It is important to update your files regularly so that they function more efficiently with SearchFilterHost.exe.

Why Do Windows Search Filter Host Consume High Cpu Usage? 

A normal Microsoft Search Filter Host file will have a standard process like any native service. When activated, the typical CPU load is no more than 40 percent with 6.1 Megabytes of maximum memory.

So, if you find yourself freezing PC or high temperature regularly while searching for files, it is likely that your CPU consumption is extremely high during Window Search.

A great way to find out whether it is the file that causes high CPU usage is by checking its status in Task Manager. So you can start by:

Go to the taskbar, right-click and choose Task Manager.

Or Ctrl + shift + esc for faster execution.

Task Manager

Then the Task Manager tab will open with all the programs on the left side. The CPU column indicates the usage percentage, and the memory column shows the consuming amount of a program.

Now, you should find the Microsoft Windows Search Indexer. If the service is running more than 40% of the CPU, it is possibly the reason for the constant freeze and crash of your PC or Laptop.

How To Fix Microsoft Windows Search Filter Host High Cpu Usage? 

The Window Search service, specifically Searchindexer.exe, Windows Search Protocol Host, and Window Search Filter Host, is developed since the Window Vista stage for enhancing the user’s experiences in terms of searching information in their drives. The service functions as a special database file recording all the names, file paths, key phrases, creation dates, and properties.

Thus, when the system is activated, which is common when you click at the Start menu and search any keywords, they search in a structured and concrete index database instead of all drives. That’s why they are able to perform a fast-paced search to produce the result within seconds.

The bigger the index database, the longer it takes to show results and the higher it consumes the CPU and memory usage of the entire drive. When using a high CPU, you can interpret that the service is working harder to gather the information you need.

In this case,  just wait for a few minutes to allow the searching process to work solo instead of working on other programs on your laptop, which can result in freezing your system.

You can also choose to disable the search process if you’re in need of your PC or laptop or don’t search files often.

Simply open the Start Menu and search Service app or go to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Administrative Tools
