What is Service Host SuperFetch and How to Fix It

I’m sure the first thing that would have come to your mind is that, what is Service Host Superfetch? How does it work? What do you do to fix Local System High Disk (svchost.exe) Usage?  Superfetch was originally created by Windows Vista as a Successor of Prefetch. It is a process that monitors your system, precisely your RAM usage and eventually creates a profile or display of all the applications and programs that run most of the time on your system. Knowing this it will load elements corresponding to those applications on your RAM well in advance so that the loading process is paced up.

Service Host Superfetch

The basic purpose of Superfetch is to fasten the application loading time in the hard drive. However, this is not the case with Solid State Drive (SSD) applications. Performance improvements cannot take place in SSD application, as by default Superfetch will not load the application in the memory. Sometimes Superfetch also causes spikes in the hard drive and CPU usage, mostly during gaming sessions. Such a case occurs in systems with a RAM memory of less than 4GB.

 Why Superfetch is So Important?

1. It reduces the boot time for apps that are not SSD based.

2. Loads most of the common apps efficiently and quickly.

3. Keeps track of your daily usage pattern.

Can Superfetch Go Awry?

Well just like any other Windows feature Superfetch can also go haywire sometimes and some issues may arise. Since most of the time Superfetch is running in the background, It uses some of the system resources such as the CPU and the RAM. Now in case you don’t have a well developed or a weak hardware system then this will lead to slowdowns and sometimes the system might crash down.

It may also happen that when you are booting Windows, your hard drive will start loading some pre-applications before windows can load its essential apps and services. This is okay if you are going to use those apps, but if not it will just end up slowing down the speed of your system.

Superfetch is not run as it’s own process, it is present under a common or generic – Service host. This is because Microsoft is shifting from the powerful and problematic .exe files to easier to deal with DLL files. DLL files are much easier to use but they require a shell to host them, hence the common service host for Superfetch.

Step 4: Next right click on the PrefetchParameters right pane and then choose New followed by DWORD value.

Step 5: Now right-click on the newly created item and select Modify. Enter the value 0 and this will automatically disable the Superfetch service.
