The Windows 10 was a complete revamp over the previous versions Microsoft had ever released. It changed the way the operating system treats hardware. Moreover, many new system processes also came into force to monitor and smoothen the functioning.

Little did the developers think the extra processes would become a menace. Service Host SuperFetch is one of them, which clogs the performance due to high disk usage. If you had a look at the Task Manager and you are still trying to recognise the process, just don’t rack your brain anymore! We have got you covered.

What Exactly is Service Host SuperFetch on Windows 10?

Service Host Superfetch

Did you ever get a chance to use a Windows XP machine? If you did, you might have known about Prefetch. Microsoft introduced it as a preloading memory manager to fasten the process of loading applications. So, is SuperFetch the same as Prefetch? Not really! It’s the successor instead.

The company broke up with Prefetch by the time they released Windows Vista. SuperFetch took over the place. What does it do? Instead of randomly preloading applications, it analyses the memory usage patterns of your computer. Analysing the patterns helps it recognising the most used apps. And, it preloads only those programs you frequently use.

The rest is obvious! Once a program is preloaded into the memory, it will launch faster. Microsoft has designed SuperFetch to take up all the available but unused memory. When your computer needs more RAM, it releases the preoccupied space to make room for the newcomer. You need to know that the process always runs in the background for the continous memory analysis.

  • If you keep the OS on an SSD, you can’t even notice the effect of SuperFetch. For Solid State Drives, preloading is unnecessary.
  • You know the process runs in the background. So, it exhausts CPU and RAM.
  • On some systems with 4 GB RAM or less, SuperFetch causes performance issues during game play sessions. It’s unclear why.
