The central processor of computers is as important as the brain of the human body. A faster CPU means that the system or device runs faster without any problems. The CPU is the part of the computer where most of the calculations are done. The most important components of the system, such as the graphics card and RAM, follow the instructions of the CPU.

You can check the memory usage status in Task Manager. The observed problem is related to the system process because it consumes a large amount of RAM when the computer starts up. Nowadays, many people are suffering from excessive CPU and RAM power consumption. Here are some ways to fix high CPU and RAM usage on Windows 10 computers.

Why does the `system’ process use a large amount of RAM?

There are many reasons why the `system’ process in Windows 10 can take up a lot of RAM, but the most common ones are as follows.

  • Too many programs running at the same time.
  • Registry hijacking.
  • Incorrect program design.
  • Running programs.
  • Insufficient amount of memory.
  • Virus or antivirus.
  • Other causes.
