Should You Use Windows 11 Compressed Memory Or Add Physical RAM

How 🪟 Windows 11 Memory Compression Works

Windows 11 memory compression works by constantly watching your background apps and shrinking idle data to save space. When you are not actively using a program, the operating system squishes its files down and stores them neatly in a special part of your RAM so your PC runs smoother without slowing down.

When the Windows 11 compressed memory feature finds idle pieces of data, the Windows 11 compressed memory feature squishes the idle pieces of data down to a smaller size. The Windows 11 compressed memory feature keeps the squished files in a special area of your RAM. When you click back on that background app, Windows instantly expands the files back to the normal size. The entire process happens in milliseconds.

This feature offers several clear benefits:

• It reduces how often your computer has to use the slow hard drive for virtual memory.
• It keeps your system running smoothly even when you have multiple apps open.
• It works completely automatically in the background without needing your attention.

Windows 11 memory compression is not magic because compressing and decompressing data takes a tiny amount of your processor's power. On very old or weak computers, this extra work can sometimes cause a slight stutter. However, on modern computers, the processor handles the memory compression task easily without slowing down your everyday work.

Memory Compression vs. Adding Physical RAM

Choosing between memory compression and adding physical RAM depends on how you use your computer and what your hardware can handle. Let us compare the two approaches directly.

Memory Compression:

• Cost: Free. It comes built right into Windows 11.
• Installation: Requires no physical work or opening your computer case.
• Limitation: It can only stretch your current memory so far. If you have 8 gigabytes of RAM, compression helps, but it cannot turn 8 gigabytes into 32 gigabytes of heavy gaming power.

Adding Physical RAM:

• Cost: Requires buying new hardware sticks.
• Installation: Requires opening your laptop or desktop computer to insert the new memory chips (though some modern laptops have memory soldered down and cannot be upgraded).
• Benefit: Gives your computer actual physical room to breathe. Your apps get their own dedicated space without needing to share or get squished.

Adding physical RAM gives your computer actual hardware space to breathe by installing new memory chips inside your desktop or laptop. This hardware upgrade gives your apps their own dedicated room to run smoothly without needing to share space or rely on compressed memory files.

How to Check Your Memory Compression Status Using PowerShell

1. Click the Windows Start button on your taskbar.
2. Type PowerShell in the search box.

   

3. Right-click on Windows PowerShell in the search results and choose Run as administrator.
4. If a security warning window pops up asking if you want to allow this app to make changes to your device, click Yes.

If you recently changed your memory compression settings, you may also want to restart the background service that manages system maintenance. In the same administrator PowerShell window, you can restart this service by running the following commands one at a time, pressing Enter after each one:

Before you turn off the Windows 11 memory compression feature, you must consider potential slowdowns and heavy hard drive usage that happen when your RAM fills up. While disabling memory compression might give a tiny boost to competitive gaming, turning off memory compression stops Windows from shrinking background data, which can cause your computer to lag.

When you disable memory compression, Windows loses its ability to squish inactive background data. If your physical RAM fills up, Windows immediately starts dumping that data onto your hard drive page file. This sudden switch to hard drive storage causes noticeable stuttering, freezing, and slow response times when switching between open windows.

If you have a computer with a low amount of physical RAM—such as 4 gigabytes or 8 gigabytes—leaving memory compression enabled is almost always the better choice. Disabling it on low-memory systems will likely make your computer feel much slower during daily multitasking.

How to Tell If You Need More Physical RAM

Telling if you need more physical RAM is easy when you use the built-in Task Manager tool on your Windows 11 computer. By opening the performance tab and checking your memory usage percentage, you can quickly see if your system is running out of space and needs a hardware upgrade.

1. Press the Ctrl + Shift + Esc keys on your keyboard at the same time to open the Task Manager.
2. If the window looks small and simple, click the More details option at the bottom of the window.
3. Click on the Performance tab at the top of the window.
4. Click on Memory in the left-hand menu.
5. Look at the graph and numbers on the screen. Pay close attention to the In use (Compressed) number and the percentage at the top right.

If your memory usage regularly sits between 80% and 95% while you do your normal daily work, your computer is struggling with its current physical RAM limit. In this scenario, memory compression is working overtime to keep your system afloat. Buying and installing more physical RAM will give your system immediate relief and make your computer feel brand new.

Summary

Windows 11 memory compression helps your PC run smoothly by shrinking idle background data, but it is not a permanent fix for heavy multitasking. While the built-in feature is free and works automatically, upgrading your physical RAM is still the best long-term solution if your system constantly runs out of memory space.
