What is the SysMain or Superfetch?
SysMain, earlier known as Superfetch, is a service in Windows 10 that aims to improve system performance over time.
It studies your RAM usage patterns and identifies programs you run most often on your PC. Once Superfetch has this information, it preloads these programs into your RAM. When you launch these programs, you’ll see them load much faster.
However, some users have reported that SysMain can cause performance issues on their systems. Some of these reported issues include constant 100% disk utilization, overheating leading to system shutdown, slow bootup time when you start your computer, and performance issues while gaming.
If you are facing any of these issues, disabling SysMain may resolve the problem.
