Windows 11, the newest version of the Microsoft operating system, comes with many exciting features, making it a big improvement from Windows 10. But, some users are dealing with a problem of high RAM or memory usage. This issue happens because of different reasons, making Windows 11 not work as well as it could on laptops and PCs.

If you’re one of those facing this problem and want to boost your computer’s performance or increase your laptop’s RAM, you’re in the right spot. You can go through these effective solutions to reduce memory usage in Windows 11. You can also look at what is Memory Usage on Windows and how to check Memory Usage on Windows 11. Just follow the whole article to make your PC work better without hassle.

What Is Memory Usage on Windows?

Memory usage on Windows is the amount of random access memory (RAM) that is currently being used by the operating system, applications, and other processes. RAM is a type of volatile memory that is used to store data that is being actively used by the computer. When the computer is turned off, all of the data in the RAM is lost.

However, upon restarting or booting up the system, background services, operating system functions, and actively running applications begin to utilize the available RAM.

If the memory usage percentage is excessively high, it can lead to performance issues such as slow responsiveness, lags, or even system freezes.

Therefore, balancing and managing memory usage in Windows is fundamental for ensuring an efficient and smooth computing experience. Regularly monitoring memory usage can help you prevent performance degradation.

How to Check Memory Usage on Windows 11

There are a few different ways to check memory usage on Windows. One way is to use Task Manager. To open Task Manager, press Ctrl + Shift + Esc. In Task Manager, click the Performance tab. Under Memory, you can see how much RAM is currently being used and how much RAM is free.

Another way to check memory usage is to use Resource Monitor. To open Resource Monitor, press Windows + R to open the Run dialog box. Type resmon and press Enter. In Resource Monitor, click the Memory tab. You can see a more detailed view of memory usage on this tab, including which processes are using the most RAM.
