Service Host SuperFetch High Disk Issues – A Brief Discussion

Service Host SuperFetch creates a high disk issue as it takes more space to perform the app pre-loading process. Besides its incredible protective functionality, Service Host service is responsible for the unnecessary memory blockage issues.

how to fix service-host-superfetch

  • SuperFetch always runs in the background that reduces the use of processing units as well as corrupts the memory spaces. As result, the CPU fails to give a real-time performance. Moreover, you can’t install any external programs due to the memory blockage issue. Similarly, the system starts to lag on a frequent basis.
  • SuperFetch doesn’t remove the basic app loading process into the RAM or buffer. So, it relocates the loading process earlier than starts to download. Thus, while the actual loading process starts, the entire process slows down. It may happen due to a lack of memory spaces. Furthermore, it shows the message to reallocate the memory.
  • The system Startup process gets sluggish due to the pre-allocation of the memory spaces. SuperFetch preloads a bunch of data from the hard disk drive or RAM memory. Thus, it decreases the system performance.
  • If Windows 10 is installed on the SSD (Solid State Drive), then your system doesn’t need to reload the programs. But, SuperFetch is one of the culprit services that always prefers the preloading process.

Why Do You Need Disable SuperFetch Service?

Service Host SuperFetch acts as a drive-catching service. It copies all the files before loading and stores them into the RAM. This approach increases the booting speed but decreases the performance indirectly.


    • If you use old or obsolete hardware, then the service causes a high disk usage problem. It corrupts the memory spaces and prevents installing the new files. Moreover, you won’t able to re-install your system driver without removing this annoying issue.
    • Even, you won’t able to compute the shortest jobs in your system as the SuperFetch always runs as a background app and stores the recently accessed files into the primary memory.
    • Your system starts to lag as the I/O devices stop responding.
