Many users notice that their windows computer slows down after running for a while, even if the hardware is new or powerful. This issue can affect both regular laptops and high-performance gaming systems. To address this, it's useful to understand why Windows consumes RAM and learn how to release it effectively.
Why Windows Uses Up RAM
RAM (random access memory) is a crucial component of your computer’s performance. It stores the data and applications currently in use, allowing your system to access them quickly. As more applications and browser tabs are opened, RAM usage increases, and this can lead to slower performance.
Even with a large amount of RAM, such as 16GB, you might still see slowdowns when launching new applications or switching between programs. This isn't necessarily due to insufficient RAM, but rather how Windows allocates and manages it.
When you open Task Manager, it often shows that memory usage is around 50-60% even when no intensive programs are running. This is because Windows runs background processes and services, along with the applications you have open. Another reason is a feature called Superfetch (now known as SysMain), which preloads frequently used applications for quicker access. While this feature can improve response times, it can also occupy a large portion of your RAM.
More importantly, some applications don’t release their memory when closed. As a result, previously used RAM remains allocated, reducing the amount available for other tasks. This can lead to performance issues, particularly when you try to run new applications.
Understanding Memory Leaks and Performance Issues
When applications hold onto RAM even after being closed, it causes a problem known as a memory leak. This can result in stuttering, lag, and system freezing, especially after prolonged use or when running multiple programs. If your computer has 8GB of RAM or less, these issues are more likely to occur, but even users with more RAM can experience problems when running memory-intensive tasks like gaming or video editing.
If you leave your computer on for long periods or often put it in Sleep mode, Windows might not automatically release the memory from closed applications. While having RAM in use isn’t a problem in itself, performance issues can arise if new programs cannot access enough memory.
