If your Windows 11 PC feels slow, freezes while multitasking, or struggles when you have several applications open, high memory usage could be one of the reasons.

The good news is that Windows 11 includes a built-in tool called Task Manager that lets you see which apps and processes are using your computer's RAM.

In this guide, you'll learn how to check RAM usage in Windows 11, identify applications consuming the most memory, and reduce unnecessary memory usage safely.

What Is RAM?

RAM stands for Random Access Memory.

It is the temporary memory your computer uses to store information that applications need while they are running.

For example, when you open:

* Google Chrome

* Microsoft Word

* Photoshop

* A video editor

* A game

these applications use RAM while they are active.

When your available RAM becomes very low, Windows may need to rely more heavily on your storage drive, which can make the computer feel slower.

How to Check RAM Usage in Windows 11

The easiest way to check memory usage is through Task Manager.

Step 1: Open Task Manager

Press:

Ctrl + Shift + Esc

This keyboard shortcut opens Task Manager directly.

You can also right-click the Start button and select Task Manager.

Step 2: Open the Processes Tab

Once Task Manager opens, select Processes.

You'll see running applications and background processes.

Step 3: Find the Memory Column

Look for the Memory column.

This shows how much RAM each running application or process is currently using.

You can click the Memory column to sort the list and identify the applications using the most RAM.

How to Find the Apps Using the Most RAM

After sorting by Memory, the applications near the top are using the largest amount of RAM.

For example, you might see:

| Application | Memory Usage |

| --------------- | -----------: |

| Google Chrome | 2.4 GB |

| Microsoft Edge | 1.6 GB |

| Adobe Photoshop | 1.3 GB |

| Microsoft Teams | 800 MB |

| File Explorer | 200 MB |

These numbers are only examples. Actual memory usage varies depending on what you're doing.

A browser with many open tabs can use considerably more RAM than a browser with only a few tabs.

How to Check Total RAM Usage

Task Manager can also show your overall memory usage.

Select:

Task Manager → Performance → Memory

Here you can see information such as:

* Total installed RAM

* RAM currently in use

* Available memory

* Memory speed

* Number of memory slots

* Memory usage over time

This gives you a better understanding of whether your computer is running low on available memory.

How Much RAM Is Being Used?

Windows may use a significant amount of your available RAM even when you're not actively running many applications.

This isn't necessarily a problem.

The important question is whether your computer is experiencing performance problems and whether memory usage remains consistently high.

If memory usage is regularly close to maximum capacity while you are working, your PC may benefit from reducing background applications or adding more RAM, depending on the hardware.

Why Does Chrome Use So Much RAM?

Web browsers can use a lot of memory because each tab, extension, website, and browser process can require resources.

For example, having:

* 30 browser tabs

* Multiple extensions

* Video streaming

* Web applications

* Online meetings

open simultaneously can significantly increase memory usage.

How to Reduce Chrome RAM Usage

Try:

* Closing unused tabs

* Removing unnecessary extensions

* Restarting Chrome

* Using Chrome's memory-saving features

* Closing web applications you are no longer using

You don't necessarily need to close your entire browser if only a few tabs are causing high memory usage.

How to Close an App Using Too Much RAM

If an application is consuming excessive memory and you don't need it, you can close it normally.

If the application has stopped responding, Task Manager may allow you to end the task.

To End a Task:

1. Open Task Manager.

2. Select Processes.

3. Find the application.

4. Select it.

5. Click End task.

Important

Don't randomly end Windows system processes.

Some background processes are essential for Windows or other applications to function properly.

If you don't recognize a process, research it before ending it.

What Is the Difference Between RAM and Storage?

RAM and storage are different.

RAM

RAM is temporary working memory used by active applications.

Storage

Storage refers to your SSD or hard drive where Windows, applications, and files are permanently stored.

For example:

16 GB RAM + 512 GB SSD

means the computer has 16 GB of working memory and 512 GB of storage.

Upgrading an SSD increases storage capacity and can improve storage performance, but it does not increase the amount of RAM.
