My Windows 10 Task Manager is Showing 100% Disk Usage

There’s a couple of reasons why your Windows 10 disk usage will hit 100% at some point. But there are ways to tune-up Windows 10 and mitigate the problem.

When your Windows 10’s disk usage hits 100% after looking at your Task Manager, here’s what you can quickly do.

1. In your Task Manager, click the Processes tab (like in the image above);
2. Sort the processes running by clicking the Disk column;
3. Find out and list your top 10 running apps ;

You have to be very observant about step 3. The applications can and might deceive you. The behavior can be very fluctuating in most cases. So, you have to find the application that is consistently hitting the top 10.

In most cases, Windows 10’s Superfetch is one of the culprits.

What is Windows 10 Superfetch Anyway?

Some say Microsoft Windows Vista gave birth to Superfetch. Technically, yes. However, Superfetch was already a part of Windows even before Vista and it was called Prefetcher. Superfetch is the improved version of Prefetcher.

When you open your Windows Task Manager, you’ll easily identify which is the Superfetch process from the applications. It will be displayed as “Service Host: Superfetch“.

What does Prefetcher or Superfetch do in Windows?

Think Superfetch as artificial intelligence (AI), a small process running in your Windows 10 background. What it does is to monitor your most frequent software and loads it to your unused RAM (memory).

Superfetch studies the pattern on how and which program you use most of the time. Then Superfetch will sort these applications and does prioritization, marking the most used as “frequently used” software. Then it preloads the said applications into your machine’s RAM.

With this preloading method, it will help your program to load faster than it used to be. This process will make things easier and organized for you.

So, if Superfetch is preloaded in RAM, then why do I get 100% disk usage?

Indeed, Superfetch uses your unused RAM to preload the most frequently used software. And whenever you boot-up your machine, it is noticed that your disk usage hits 100%. Why is this so?

This is simply because your frequent software is being preloaded from your HDD (hard disk drive) into your RAM. That is why your Windows machine feels sluggish when you boot up.

If Superfetch is the culprit why my machine is sluggish, can I disable it?

Of course, you can! There’s no risk at all if you wish to disable Superfetch to tune-up Windows 10. Not even your data will be lost.

There were reports that Superfetch tends to affect Windows 10 users while heavily working with their machine.

It seems to happen if the application or software that you are using is constantly requesting and freeing up memory under a low RAM system. This is causing the Superfetch to load and unload data. And as a result, you will notice the slowness of your Windows 10 machine.

So yeah, if Superfetch is causing sluggishness and doing more problems than the other way – as it supposed to be. Then, by all means, disable Superfetch.
