What Is Superfetch (SysMain) on Windows 10? And How to Disable It
Superfetch, also known as SysMain, is a feature in Windows 10 that helps improve the overall performance of your computer. It does this by predicting the applications and files you are most likely to use and preloading them into RAM, so they are readily available when you want to use them.
Superfetch operates by constantly analyzing your usage patterns and creating a cache of the most commonly used files and applications. By doing so, your computer can access these files and applications much faster, speeding up the overall performance of your system.
However, some users have reported that they experience slow performance due to Superfetch. This might happen when Superfetch is preloading files and applications that you don’t frequently use or need, causing a strain on your computer’s resources.
If you find Superfetch to be causing performance issues, you can disable it using the following steps:
Step 1: Press the Windows key and R simultaneously.
Step 2: Type “services.msc” and press Enter. This will open the Services window.
Step 3: Find “SysMain” in the list of Services and double-click on it.
Step 4: In the Properties window, select “Disabled” in the Startup type drop-down menu.
Step 5: Click on “Stop” to stop the service immediately.
Step 6: Click on “Apply” and then “OK” to save the changes.
Disabling SysMain or Superfetch can have both positive and negative effects on your system’s performance. While it may help alleviate some of the performance issues, it may also cause applications to launch slower, especially if you have a lot of programs installed on your computer.
