In Windows Vista and onward all Windows OS, comes along with better support for modern hardware, in the form of SuperFetch. It is a technology that is meant for managing the amount of random access memory in a particular machine in order to enhance its efficiency. It’s a less capable version of PreFetcher, which was at first introduced through Windows Vista. It underwent changes to become a part of Windows’ memory manager and now has become the latest SuperFetch.
This new technology performs the task to ensure that the more than often accessible data can be read from the fast RAM instead of the slow hard drive. It serves two goals; to decrease boot time and to interact with the defragmenter, to make applications launch faster. Overall it ensures that it does not impact the system negatively.
However, the other side of the coin is that as it is time-consuming and so needs time for adapting to any kind of usage pattern. It runs at a low priority so one may abruptly note technical glitches while it is trying to manage the random memory. In this article, you will get a vivid insight into the issues and how you can revert the unwanted Service Host Superfetch error.
What Is Service Host Superfetch Issue?

Service Host Superfetch high disk usage is rarely reported to be a dangerous sign. But it needs immediate action as this service makes maximum capability to respond to I/O requests. When this hosting service starts filling up the RAM with frequently used files, the size of these files increases over time. This is when it becomes a problem as it can take longer to sort out memory.
How Does Service Host SuperFetch Go Wrong?
If you are wondering what are the probable causes that can lead to the malfunctioning of SuperFetch then take a glance at the list mentioned below.
- Especially during gaming sessions, it causes a spike in the hard drive and CPU usage.
- If you are operating through systems with less than 4GB of RAM, then the function of SuperFetch faces a limitation.
- If periodical gameplay stutters do not get a solution, then it eventually shuffles around in memory, causing an error in the SuperFetch.
- While one boots Windows the hard drive is often overpowered to load an array of applications all at the same time. An error occurs as Windows does not get the time to load all the requisite apps and services.
- Often, issues associated with high HDD usage, degraded performance or high RAM usage, throughout heavy activities in RAM.
