How to Disable Superfetch in Windows 8

If you’re looking to optimize your PC performance and disable Superfetch services in Windows 8, you’ve come to the right place. Superfetch is a built-in Windows service that aims to improve loading times for Windows and installed applications by pre-loading frequently used programs into system resources.

However, if you have a fast HDD or SSD, disabling Superfetch can actually optimize your PC’s performance. By preventing unnecessary resource allocation, you can ensure that your system runs smoothly and efficiently.

Here’s how you can disable Superfetch in Windows 8:

  1. Open the Services snap-in by searching for “services.msc” in the Start menu or using the keyboard shortcut Windows Key + R.
  2. Scroll down to find the Superfetch service, right-click on it, and select Properties.
  3. In the Properties window, change the Startup type to Disabled.
  4. If available, click the Stop button to immediately stop the Superfetch service.
  5. Restart your system for the changes to take effect.

By following these steps, you can effectively disable Superfetch and optimize your PC performance.

What is Superfetch and How Does it Work

Superfetch is a built-in Windows service that analyzes which programs are frequently running and pre-loads them in advance by reallocating system resources, such as extra RAM. Its main purpose is to improve loading times for Windows and all installed applications, particularly on systems with slow HDDs. By anticipating which programs you use most often, Superfetch ensures that the necessary files are readily available in memory, reducing the time it takes for applications to launch.

For systems with fast HDDs or SSDs, Superfetch may have a different impact. While it still attempts to optimize performance, it can actually decrease performance and negatively impact the health of the drive. This is because it continues to allocate system resources to preload frequently used files, even when the drive can access them quickly. The constant reallocation of resources can result in excessive disk usage and may contribute to wear and tear on the drive over time.

To summarize, Superfetch is a service that aims to improve loading times by identifying frequently used programs and preloading them into system memory. While it can be beneficial for systems with slow HDDs, it may not provide significant benefits for systems with fast HDDs or SSDs and can even contribute to performance issues. In such cases, disabling Superfetch can prevent unnecessary resource allocation and potentially improve system performance and drive health.

Disabling Superfetch for Better Gaming Performance

When it comes to gaming performance, Superfetch, a built-in Windows service, can sometimes cause issues such as high disk usage and long loading times. The Superfetch service preloads files from frequently played games into memory, which can consume system resources even after you’ve finished playing. To check if Superfetch is affecting your gaming experience, open the Task Manager and look for the entry “Service Host: SysMain.” If you notice high CPU usage or sustained disk usage, it is recommended to disable Superfetch.

Disabling Superfetch can be done by accessing the Services snap-in in Windows 10. Locate the SysMain service and set the Startup type to Disabled. By disabling Superfetch, you can prevent unnecessary resource allocation and improve gaming performance. This will ensure that your system focuses its resources on the game you’re currently playing, resulting in smoother gameplay and reduced loading times.

It’s important to note that disabling Superfetch may have varying effects on different systems. While some users may experience significant improvements in gaming performance, others may not notice a significant difference. Factors such as your hardware configuration and the specific games you’re playing can influence the impact of Superfetch on your gaming experience. It’s always recommended to monitor your system resources and adjust Superfetch settings accordingly to achieve optimal performance.

So, if you’re facing issues with gaming performance, specifically high disk usage and long loading times, consider disabling Superfetch. By taking this step, you can ensure that your system resources are utilized efficiently, allowing for a smoother and more enjoyable gaming experience.
