Is your Windows 10/11 PC suffering from laggy and slow performance? Disabling SysMain, formerly known as Superfetch, can help improve your system’s performance. As you read this article, you will learn what SysMain (Superfetch) is, how to disable SysMain, and how to enable it again on your Windows 10/11 PC.
What Is SysMain (Superfetch)?
Introduced in Windows Vista, Superfetch (now known as SysMain) is a feature that was originally designed to maintain and improve system performance over time. Superfetch works by analyzing your frequently used apps. Once it gathers enough data, Superfetch preloads these apps into your RAM for easy access.
This feature was a great way to improve system performance on computers that used HDDs as a main storage drive. If you notice your RAM usage is unusually high, don’t be concerned. Superfetch only deals with RAM that’s not currently in use. As soon as your PC needs more memory, Superfetch will then release the unused memory to the current program that needs it.
Is SysMain Really Necessary?
If you have a fast, newer PC, SysMain can have an unnoticeable impact on your system’s overall performance. But if you are noticing strange problems with your computer, SysMain can be the reason why. Here are some common issues that SysMain (Superfetch) can cause:
- High CPU/RAM Usage
- High Disk Usage
- Longer System Startup Times
- Sluggish Performance On Low-Spec PCs
If you are experiencing any of these issues, disabling SysMain (Superfetch) might be a good idea.
Is Turning Off SysMain Recommended?
Most computer users should leave SysMain on by default because it helps with improving your system’s efficiency. But if you have a low-spec PC that’s struggling with poor performance, turning off SysMain (Superfetch) is an effective way to troubleshoot these issues.
