How to Disable Superfetch Windows 10?

Are you facing high disk usage or a slow system performance due to Superfetch in Windows 10? Superfetch is a Windows service designed to improve the system’s performance by caching the frequently used applications and data. However, if it is enabled, it can also cause high disk usage, making your system slow and unresponsive. If this is the case, then you should learn how to disable Superfetch in Windows 10. In this article, we will guide you through the process of disabling Superfetch and how to make sure your system runs smoothly without it.

What is SuperFetch?

SuperFetch is a Windows service that was introduced in Windows Vista and is still present in Windows 10. It is designed to improve system performance by pre-loading commonly used applications into system memory. SuperFetch works by monitoring the user’s usage patterns and loading related data and programs into memory ahead of time. When the user needs to access those programs, they are already loaded and ready to go, thus speeding up boot times and program loading times.

However, SuperFetch can be a resource hog, especially if the user has a lot of applications installed. In addition, some users may find that they don’t need or want SuperFetch running on their systems. Thankfully, it is relatively easy to disable SuperFetch in Windows 10.
