Superfetch is a Windows 10 feature introduced for two purposes. The first is to reduce the startup time and the second loads applications faster. Superfetch does this by preloading them into memory. It also tracks your usage pattern for a better preload decision. For example, if you open Chrome in the morning, it will preload Chrome in the morning hours, so the app loads faster. But sometimes, preload becomes a major cause of high disk usage. Here in this article, we will discuss how to disable superfetch in Windows 10.
