What is Service Host Superfetch

Service Host

Service host is a process name for services that runs using the dynamic system link libraries. Microsoft pivoted from using the internal Executable files (.exe) to Dynamic Link Libraries (.dll). This enhanced the code reusability and extensibility of a file. The code would be packed up in small files known as DLLs and then used and fetched whenever necessary. The downside is that the user can launch an executable file directly from the graphical user interface but can not do the same for a DLL file. DLL file has to be loaded in a shell and then executed. For this work, the Service Host was started.

Service Host Superfetch

Service Host Superfetch

Service Host Superfetch is a service that helps the system to fetch the data used in the successful execution of a program. It manages random memory in a system to enhance the proper functioning of the task. To prevent crashing of the task, Superfetch stores are created which later fetch the memory to be used from the RAM instead of the Hard Disk.

Hard to Understand? No problem, We’ll make you understand. Superfetch caching is just like data caching. In caching, the data for the commonly used program is stored in the drives beforehand so that the program can run faster the next time. Same goes for Superfetch caching. It stores the commonly needed data in the RAM so that the system doesn’t have to load it from the hard drive every time.

The Service Host Superfetch service is generally beneficial but it sometimes causes a defect too. In many systems, it causes an error where the Service Host Superfetch uses too much memory and blocks the execution of the other programs. To solve this, read the below-given section.
