High RAM usage in Windows 11 is a common problem, especially on systems with 4GB or 8GB memory. You may notice your PC becoming slow, applications freezing, or Task Manager showing very high memory usage even when you are not running heavy software.
In many cases, this happens because of too many startup apps, unnecessary background services, memory leaks, or Windows features running when they are not needed. The good part is that most of these problems can be fixed without reinstalling Windows or upgrading hardware.
In this guide, we will go through practical methods that actually help reduce RAM usage in Windows 11. You can follow these steps even if you are not very technical.
When should you worry about high RAM usage?
Not every high memory number is a problem. Windows uses available RAM to improve performance, so seeing 50–60% usage during normal work is completely normal.
You should start troubleshooting if you notice these symptoms:
- RAM usage stays above 80% with few programs open
- Your PC feels slow after startup
- Applications take longer to open
- System freezes randomly
- Games or browsers start stuttering
First, let's confirm how much RAM is actually being used before applying any fixes.
Check RAM usage in Task Manager
Before trying any fixes, first check how much RAM Windows 11 is actually using. This helps you understand whether memory is really the problem and which programs are consuming the most resources.
Windows Task Manager makes this very easy and only takes a few seconds.
Steps to check memory usage
- Right-click the Start button
- Click Task Manager
- Open the Performance tab
- Select Memory from the left panel
- Check how much RAM is currently being used
You can also open Task Manager instantly using this shortcut:
- Ctrl + Shift + Esc
Find which programs are using the most RAM
Now click the Processes tab and then click the Memory column. This will sort applications from highest to lowest memory usage.
Look for:
- Programs using unusually high memory
- Apps you don't recognize
- Apps running even when you did not open them
If you find an unnecessary program using a lot of RAM, you can right-click it and select End task to close it temporarily.
Once you confirm RAM usage is high, continue with the fixes below to reduce memory usage permanently.
Disable unnecessary startup programs
Many applications automatically start when Windows boots. Some of these are useful, but many are not necessary and only increase RAM usage and slow down startup time.
Disabling unnecessary startup apps is usually one of the easiest ways to reduce memory usage and improve performance.
How to disable startup programs
- Open Task Manager
- Click the Startup apps tab
- Look at the Status column
- Right-click apps you don't need
- Click Disable
What you can safely disable
You can usually disable these safely if you don't actively use them:
- Discord
- Spotify
- Microsoft Teams
- Game launchers
- Third-party update services
After disabling unnecessary startup apps, restart your PC and check if RAM usage improves.
Close unnecessary background apps
Even when you close applications, some programs continue running in the background. These background apps can slowly consume RAM and system resources without you noticing.
Windows 11 allows you to control which apps are allowed to run in the background, and disabling unnecessary ones can reduce memory usage.
How to stop background apps
- Open Settings
- Go to Apps
- Click Installed apps
- Click the three dots next to an app
- Select Advanced options
- Under background permissions choose Never
Apps you should consider restricting
- Apps you rarely use
- Third-party tools
- Game launchers
- Communication apps you don't keep open
You don't need to disable everything. Focus only on apps you don't use daily. This keeps your system optimized without breaking useful features.
Restart Windows Explorer
Sometimes high RAM usage happens because Windows Explorer (the process that controls the desktop, taskbar, and file manager) gets stuck or starts consuming more memory than normal.
Restarting it refreshes the Windows interface and can immediately reduce memory usage.
How to restart Windows Explorer
- Open Task Manager
- Scroll down to find Windows Explorer
- Right-click it
- Click Restart
Your taskbar and desktop may briefly disappear for a second. This is normal.
After restarting, check memory usage again in Task Manager to see if there is any improvement.
Disable SysMain service
SysMain (previously called Superfetch) is a Windows service designed to preload frequently used apps into memory to make them launch faster. While this can help on some systems, it can also cause high RAM usage on low memory PCs.
Disabling this service can sometimes reduce memory pressure, especially on systems with limited RAM.
How to disable SysMain
- Press Win + R
- Type the following command
- Press Enter
- Find SysMain
- Double-click it
- Click Stop
- Set Startup type to Disabled
- Click Apply then OK
After making this change, restart your PC and check memory usage again.
Scan for malware
If your RAM usage stays high even when no heavy programs are open, malware or unwanted software could be running in the background. Some malicious programs are designed to silently consume system resources.
Running a quick security scan can help rule this out.
How to scan your PC using Windows Security
- Open Settings
- Go to Privacy & Security
- Click Windows Security
- Select Virus & threat protection
- Click Quick scan
Extra things you can check
- Uninstall programs you don't remember installing
- Check browser extensions
- Avoid running cracked or suspicious software
If malware is detected, remove it and restart your PC before checking RAM usage again.
Increase virtual memory
Virtual memory (also called the paging file) allows Windows to use part of your storage as extra memory when your RAM is full. Increasing it can help reduce lag and crashes on systems with limited RAM.
This does not replace real RAM, but it can improve stability when memory usage gets too high.
How to increase virtual memory
- Press Win + R
- Type the command below
- Go to the Advanced tab
- Under Performance click Settings
- Open the Advanced tab again
- Click Change under Virtual Memory
- Uncheck Automatically manage paging file size
- Select your main drive (usually C:)
- Click Custom size
Recommended values
- Initial size: 1.5 × your RAM
- Maximum size: 3 × your RAM
- Click Set
- Click OK
- Restart your PC
After restarting, Windows will use the new virtual memory limits which can help reduce slowdowns caused by high RAM usage.
Disable visual effects
Windows 11 includes many animations and visual effects that make the interface look modern, but they also consume RAM and system resources. On low-memory systems, disabling these effects can make the system feel noticeably faster.
If your system already struggles with memory usage, prioritizing performance over appearance is usually a better choice.
How to disable visual effects
- Press Win + R
- Type the command below
- Open the Advanced tab
- Under Performance click Settings
- Select Adjust for best performance
- Click Apply then OK
Reducing visual effects is a common performance optimization technique used not only in Windows but also in lightweight Linux environments where performance is prioritized over animations.

After applying these changes, you may notice faster window opening, smoother navigation, and slightly lower RAM usage.
Update Windows 11
Sometimes high RAM usage is caused by bugs or memory leaks in Windows itself. Microsoft regularly releases updates that fix performance issues, security problems, and resource management bugs.
Keeping Windows updated ensures you are not dealing with already fixed issues.
How to check for updates
- Open Settings
- Go to Windows Update
- Click Check for updates
- Install any available updates
- Restart your PC if required
After updating, check Task Manager again to see if memory usage improves.
Stop Microsoft Edge high RAM usage
Microsoft Edge runs several background processes even when you are not actively using the browser. Features like Startup Boost and background extensions can consume RAM unnecessarily, especially on low memory systems.
If you don't use Edge as your main browser, limiting its background activity can help reduce RAM usage.
Disable Edge background activity
- Open Microsoft Edge
- Type this in the address bar:
- Disable Startup boost
- Disable Continue running background extensions and apps
Optional: Uninstall Microsoft Edge (advanced users)
Windows does not normally allow removing Edge easily because it is integrated into the system. However, advanced users who never use Edge sometimes remove it to reduce background resource usage.
- Open Command Prompt as Administrator
- Navigate to the Edge installer folder
- Run this uninstall command:
For most users, disabling background activity is enough and much safer than uninstalling the browser.
When you should upgrade your RAM
If you have already tried the fixes above and RAM usage still stays high during normal use, your system may simply need more memory. Software optimizations help, but they cannot fully compensate for very limited RAM.
Windows 11 can run on 4GB RAM, but it is not always a smooth experience, especially if you use modern browsers, multitask, or play games.
Recommended RAM for Windows 11
- 4GB RAM → Basic usage only (may feel slow)
- 8GB RAM → Recommended for normal users
- 16GB RAM → Best for gaming and heavy multitasking
If your system cannot be upgraded, another option some users consider is switching to a lighter operating system designed to run better on limited hardware. We discussed this in another guide: Why you should switch to Linux in 2026
For most users, upgrading from 4GB to 8GB RAM provides the biggest performance improvement compared to any software tweak.
Bonus tips to reduce RAM usage
If you still want to squeeze a little more performance out of your system, these small optimizations can also help reduce memory usage.
- Restart your PC regularly instead of keeping it running for days
- Reduce the number of browser tabs you keep open
- Uninstall programs you no longer use
- Avoid running multiple antivirus programs
- Use lightweight software alternatives when possible
- Keep your drivers updated
If your hardware is older and struggles even after optimization, using a lightweight operating system can sometimes provide better performance than trying to optimize heavy systems. You can read more about this here:
