What is Service Host Superfetch? Fix its high CPU!: Before we move on to Superfetch it is viable for us to know about Prefetch in Microsoft Windows. As known, it will give us a better knowledge of the Service Host Superfetch. In Microsoft Windows a Prefetch is a component in Windows XP. The Prefetch is a component of the Memory Manager that is responsible for speeding up the Windows boot process. The component is required to shorten the amount of time a program takes for it to start up. The Prefetch accomplishes the task by caching files that are needed by an application to RAM as the application is launched. This, in turn, consolidates the disk reading and reduces the disk in seeking. Similarly, when the Windows Vista was released the Prefetch was extended to SuperFetch and ReadyBoost.

What does the SuperFetch do?

The task of the SuperFetch is to accelerate the launch time of applications by monitoring and adapting to application usage pattern over a long period of time. Its duty is to cache the majority of the files and the data needed by them, into memory in advance. This is done so that they can be accessed very quickly when needed. Similarly, the ReadyBoost works with the same functionality in the Windows Operating System. It has a component, which replaces the Prefetcher for the boot system if the system has 700mb or more of RAM.

What is Service Host Superfetch? Fix its high CPU!

In simpler words, when a Windows system starts up the components of many files need to be read into memory and then need processing. Often different parts of the same file are loaded at different periods of time. As a result, of which, a significant amount of time is spent escalating from one file to another and then back again. This process is done multiple of times, even though a single access could prove to be more efficient. The Prefetcher’s job is to watch what data is accessed during the booting process and keeping a record of a trace file of the activity. The boot prefetcher then continues to watch over such activities until thirty seconds of use (after the user’s shell begins).

Alternatively, the prefetcher continues to watch over until and after sixty seconds after all the services has ended after initializing, sometimes, extending to two minutes after the system has booted. This is considered based one whichever initializes first. This helps the load code and data to load efficiently later when the system boots by using all the information recorded in the trace file. Similarly, application prefetching works in a similar manner. Although, the prefetching is limited to a single applications startup. Where, only the first ten seconds of activity of an application is monitored. After which, the prefetcher stores all the trace files in the Prefetch folder inside the Windows folder.

By now, it should be clear as to what is the concept behind the SuperFetch. Moving forward to the subject let us now get an elaborate view of the issues caused by it. If a user is to keenly keep a watch or observe the SuperFetch and its functionality, one shall notice that it uses a lot of power of the CPU. The usage of any other property or application in the system remains zero to normal. However, if you are to check, the CPU usage of power is always at a high draining it of all its power. The Service Host Superfetch takes up a lot of power which is quite an issue that needs due dealing with.

What is the process to disable the Service Host Superfetch?

The process to disable the Service Host Superfetch is quite simple and requires step-by-step action that a user must take. To disable the Service Host Superfetch a user must do the following:

  • First step: Open the ‘Start Menu’

Upon opening which moves your cursor to the ‘Search bar’ and the type ‘Services’ and hit the ’Enter’ button on the keyboard.

  • Next step: A user is to look for the ‘SuperFetch’

When a user finds the ‘Super Fetch’ option in the list of applications, they are to right click on it and then choose the ‘Properties’ option.

  • Last step: Click on the ‘Start Up’ option

When a user finds the ‘Start Up’ option they are to right click on it and shall be directed to its settings. Upon finding which, a user is to select the ‘Disable’ option. This action will disable the ‘Start Up’ action of the Service Host Superfetch which in turn shall automatically prevent it from activating or popping up on a users screen when the system boots. Thus, it saves a lot of power from being wasted on the actions of the Service Host Superfetch that it consumes to automatically start up when the system boots.

If you face any similar qualms about the CPU consuming a lot of power for applications that are not even needed or in use should follow these simple steps. These steps not only help disable the Service Host Superfetch but are also used to disable various other unwanted applications that have been laying around in the system memory. There are times when a user does not even know about the existence of many applications that have been spammed into the system. Additionally, sometimes a user loads an application, which have zero to no use. This, in turn, slows down the system by reducing its power usage on major applications and utilizing it on useless applications. It causes the system, CPU, to lose a lot of power. If the CPU loses power it automatically slows the system and causes the system to heat up unnecessarily for the use of applications that are not needed.

In order to have an efficient running of your personal computer, it is mandatory to have your antivirus up to date. Please note that occasional cleaning of your system will not only improve the efficiency of the computer but also save a lot of power. Every application that we use enhances our system and its functionality. Additional to which it also reduces and consumes a lot of energy. So it is highly recommended to take care of your personal computer by keeping these things in check.
