On many occasions, users of Windows You notice your system slowing down for no apparent reason. Despite having enough RAM installed, some processes seem to take longer than usual, or even gaming performance degrades for no apparent reason. One of the lesser-known but most influential suspects in these cases is standby memory. Standby Memory.

La standby memory It's essentially a type of cache that the operating system uses to store data from recently closed or background programs. Windows maintains it so that if you reopen one of those programs, it will load more quickly. However, When this type of memory is not released properly, it can prevent other processes from accessing RAM., generating bottlenecks that lead to a drop in performance.

Why it can become a problem

The use of Standby Memory does not usually represent a problem in most cases, but there are situations in which Windows does not handle its release correctlyThis causes abnormal RAM consumption, leaving the system without the resources to open new applications or run games smoothly. Many users have found that the queue list is not automatically emptied., especially in recent versions of the operating system, which leads to its saturation.

RAMMap shows you technical information such as private processes, paging and non-paging memory, mapped files, etc.Beyond the analysis, what's most interesting is its emptying function. You can learn how to use it in this article. article about VMMap.

From the top menu "Empty", you can select the option Empty Standby ListThis will directly free up this type of memory without affecting other essential system segments. It's a safe and effective method if used correctly.

Process Automation with Task Scheduler

Some users have preferred to automate the periodic cleaning of the Standby Memory. This is done with a small application called EmptyStandbyList.exe, which you can find on trusted sites like wJ32.orgThe process involves creating a scheduled task that runs this tool every so often.

Basic steps to automate with the scheduler:

  • Download the EmptyStandbyList executable from the official website.
  • Copy it to a folder inside “C:\Windows” or another accessible location.
  • Open Task Scheduler and create a new task.
  • On the General tab, enter a name for the task and enable the Run with higher privileges option.
  • Under “Triggers,” select “Daily” or “Every 5 minutes,” and select the indefinite repeat option if desired.
  • Under "Actions," click "Start a program" and select the EmptyStandbyList file.
