High hard drive and CPU usage with Super Fetch is no stranger to Windows 10 users, and the latest update is making itself felt. Windows 10 is Microsoft’s latest operating system, and the company offers users security updates and new features.
SuperFetch is a process that has recently plagued Windows 10 users. The high CPU usage of “Service Host: Superfetch” consumes a lot of memory, and you can monitor it in Task Manager.
What causes the high HDD and CPU utilization when using Superfetch?
Superfetch can be compared to disk caching. The service helps to copy all memory of frequently used files to the system RAM. That’s why programs run much faster when using it. However, there is one serious problem with this service, which occurs if you do not have enough or the latest hardware to support caching. In this case, the Host Superfetch service causes a heavy load on your hard drive.
The Superfetch error is overlooked by many, but sometimes it can cause real alarm as the system responds to I/O service requests as best it can because of the high load on the hard disk. It then tends to empty RAM memory and starts copying new files recently accessed by the user.
Once the disk is full, the service automatically slows down, freeing up memory for other applications and reducing disk space on board.
