how to stop superfetch cmd

This post will explain how to stop superfetch cmd. Superfetch is a feature in Windows 10 and 11 that serves two objectives. The first is to reduce boot time, and the second is to make app loading faster. This is accomplished by Superfetch preloading them into memory. It also keeps track of your usage habits in order to make better preloading decisions. If you open Chrome in the morning, for example, it will preload Chrome during certain hours, making the program load faster. However, prefetching can occasionally be a key source of high disc utilization. We’ll go through how to stop superfetch in Windows 10 and Windows 11 in this article.
