Home windows 10 is a particular enchancment over earlier variations in some ways—however it may additionally really feel sluggish and sluggish when it isn’t configured correctly. Of the numerous methods to enhance Home windows 10 efficiency, there’s one lesser-known function that it’s best to find out about: SuperFetch.
On this article, you’ll be taught the whole lot it’s essential to find out about what SuperFetch is, the way it works, why it is perhaps problematic, and find out how to disable it if it’s inflicting points.
What Is SuperFetch? How It Works
The official description of the SuperFetch service says that it “maintains and improves system efficiency over time,” however that’s imprecise and doesn’t clarify the entire story.
SuperFetch is a function that was launched again in Home windows Vista. It sits quietly within the background, continually analyzing RAM utilization patterns and studying what sorts of apps you run most frequently. Over time, SuperFetch marks these apps as “continuously used” and preloads them into RAM forward of time.
The concept is that if you do need to run the app, it can launch a lot quicker as a result of it’s already preloaded in reminiscence.
By default, SuperFetch is designed to take up all of your accessible RAM area with preloaded apps. Don’t fear: it solely offers with unused reminiscence. As quickly as your system wants extra RAM (e.g. to load an app that wasn’t preloaded), it relinquishes the wanted reminiscence as crucial.
Notice that SuperFetch isn’t the identical factor as Prefetch, which is the preloading reminiscence supervisor that was launched again in Home windows XP. SuperFetch is definitely the successor to Prefetch. What’s the distinction? Prefetch didn’t analyze utilization patterns over time and alter its preloading parameters accordingly.
Is SuperFetch Actually Obligatory?
For probably the most half, SuperFetch is beneficial. When you’ve got a contemporary PC with common specs or higher, SuperFetch almost definitely runs so easily that you simply gained’t ever discover it. There’s an excellent likelihood SuperFetch is already operating in your system proper now and also you didn’t even know.

- Since SuperFetch is all the time operating within the background, the SuperFetch service itself is all the time utilizing some CPU and RAM.
- SuperFetch doesn’t get rid of the necessity to load apps into RAM. Moderately, it relocates the loading to an earlier time. Every time that loading occurs, your system nonetheless experiences the identical slowdown as if you happen to have been launching the app with out SuperFetch.
- System startup may be sluggish as a result of SuperFetch is preloading a bunch of information out of your HDD to RAM. In case your HDD runs at 100% for a couple of minutes each time you begin or restart your laptop, SuperFetch may very well be the perpetrator.
- The efficiency features of SuperFetch could also be unnoticeable when Home windows 10 is put in on an SSD. Since SSDs are so quick, you don’t really want preloading. If this pursuits you, take a look at our information to shifting Home windows from HDD to SSD.
SuperFetch has additionally been recognized to trigger efficiency points whereas gaming, notably on techniques which have 4GB of RAM or much less. It’s unclear why this occurs as a result of it doesn’t happen for everyone, however we suspect it has to do with RAM-heavy video games that continually request and release reminiscence, which can trigger SuperFetch to continually load and unload information.
Is it secure to disable SuperFetch? Sure! There is no such thing as a danger of uncomfortable side effects if you happen to determine to show it off. Our advice is that in case your system is operating nicely, depart it on. When you’ve got points with excessive HDD utilization, excessive RAM utilization, or degraded efficiency throughout RAM-heavy actions, then strive turning it off and see if it helps.
