How To Enable Superfetch To Speed Up Computer Performance

If you’re looking to speed up your computer’s performance, one way to do so is to enable Superfetch. This Windows feature learns which programs you use the most and preloads them into memory, reducing load times and improving overall system responsiveness. By enabling Superfetch, you can save valuable time and enhance your computing experience. Keep reading to learn how to enable Superfetch and take advantage of its benefits.

What is Superfetch?

Superfetch is a feature in Windows operating systems that helps proactively load frequently used applications and data into the memory, thereby making them readily accessible and providing faster access times. This technology monitors the usage patterns of various applications and optimizes the memory usage to enhance the overall performance of the system. With Superfetch, Windows ensures that the frequently used applications are always kept ready to use, which leads to higher responsiveness and speed of the system.

What is the Purpose of Superfetch?

Superfetch is a technology introduced by Microsoft to improve system performance by predicting which applications and files will be used next and preloading them into memory. The purpose of Superfetch is to reduce application loading times and improve system responsiveness by minimizing the time taken by the hard drive to access data. It monitors the user’s behaviour and preloads the applications that are frequently used, thereby reducing system lag and providing a quicker response time to the user. Overall, the purpose of Superfetch is to enhance the user experience on Windows-based operating systems.

When to Enable Superfetch?

Superfetch is a Windows feature that preloads frequently accessed data into RAM to reduce startup and application launch times. However, it can also cause performance issues on systems with limited memory. Users should enable Superfetch on systems with 4GB or more of RAM, and disable it on systems with less than 4GB or when experiencing performance issues.

Troubleshooting Issues that Arise from Enabling SysMain

Enabling SysMain on a computer can provide numerous benefits, such as improved performance and faster access to frequently used applications. However, it is not uncommon for issues to arise when SysMain is enabled. These issues may range from minor annoyances to serious malfunctions that can affect the overall functioning and stability of the computer. Here are some of the common issues to be aware of when enabling SysMain:

  • High CPU Usage: SysMain, also known as Superfetch, is a background process that runs continuously on your computer. This process can consume a significant amount of CPU resources, especially when the system is first starting up or when launching new applications.
  • Excessive Disk Usage: SysMain also accesses the hard disk drive regularly to cache frequently used files and applications. While this can improve performance, it can also lead to excessive disk usage, especially when the drive is already running low on space.
  • Slow System Startup: Enabling SysMain can cause the computer to boot up more slowly, especially if there are numerous applications installed on the machine. This is because SysMain is busy caching these applications and files in the background, slowing down the startup process.
  • Frequent Crashes and Freezes: If SysMain encounters an error or becomes corrupted, it can cause the entire system to crash or become unstable. Frequent crashes and freezes may indicate that SysMain is causing errors in the cache, which may need to be cleared or rebuilt.
  • Compatibility Issues with Older Hardware and Software: Some older hardware and software may not be compatible with SysMain, leading to compatibility issues and system crashes.

Frequently Asked Questions

Where is the Prefetch data stored?

Prefetch data is stored in the C:\Windows\Prefetch folder in the Windows operating system. It helps improve application launch times by caching frequently used data.

Should I enable Prefetch?

It depends. Prefetch can impact performance positively or negatively, depending on hardware configuration and workload. Consult system documentation or professional advice.

Should I turn Prefetch on or off in SSD?

It is recommended to turn off prefetch on SSDs as it is designed for traditional hard drives, which slows down SSD performance.


In conclusion, enabling Superfetch can improve the overall performance of your system by preloading frequently used applications into memory. This feature minimizes the time taken to launch your favorite programs and ensures that your computer responds faster. Therefore, it is advisable to enable Superfetch to optimize your Windows operating system’s performance.
