Prefetch was introduced in the Windows system back when Windows XP was launched. It is a system service that works in the background taking up no power from the CPU. This service aims to improve the application loading time on a Windows system.
Prefetch is built into the Windows OS to improve the user experience. It is not a necessary system. So if you want to disable it, there will be no issues. But how does the prefetch actually work in a Windows system? Is it really good? If not, then how can you disable it? Let’s find the answers to all these questions in this article.
What is prefetch?
Prefetch is a Windows system service that silently fetches resources before an application in the future requires them. It creates a cache file where the resource information is stored. As soon as that application is launched, Windows comes back to this cache file and using the already fetched resources, and it ends up opening the application faster than usual. These cache files are created based on the daily behavior of the Windows user. It creates these cache files for all the applications that the user frequently opens up.
