Microsoft has always been lousy while handling elements of its operating system. The launch of Windows 10 came as a breath of fresh air. The tech giant introduced better support for malware and included a couple of new features to its operating system.
Amidst all the added features, some of the traditional features have been retained by Windows. These contribute to enhancing the experience of using the OS. Service host SuperFetch is one such feature that was initially introduced in Windows Vista.
The Service host SuperFetch feature analyses the RAM usage of the system and on the basis of that generates programs and software which are used more frequently. This makes it easy to access these programs on a regular basis.
The following article shall guide you on this vintage feature of the Microsoft operating systems. This can be used to optimize the memory of your computer. The article shall also cover ways to fix the feature or troubleshoot basic errors and bugs. Read on to find out more.
A handy memory manager
Service host SuperFetch can be understood as an efficient memory manager. It can be used to track the trends and analyze patterns to optimize memory. The process makes use of the basic tracking algorithm. It helps to create a cache profile of frequently accessed programs and applications. The feature keeps a close watch on the programs being used on the system.
When you leave an app or software, SuperFetch coordinates with the memory manager. This makes sure that the program can be loaded quickly in the near future. This is done by adjusting the cache memory of applications to optimize the time taken to open a frequently used app.
How to spot the SuperFetch process?
Before you make any changes to the process, it is necessary to be sure about the effect that SuperFetch has on your system. Spouting the process is a bit difficult because it is not easily visible in the task manager. This is primarily because SuperFetch is not listed as an individual process in Windows 10 and can be found under the general name of ‘Service Host.’
In order to locate the process, find the service named “Service Host: SuperFetch” from a long list of options.
