Running into issues with low memory on your Windows 11 computer can be incredibly frustrating. This problem often manifests as the dreaded “Your computer is low on memory” error message. When your system doesn’t have enough Random Access Memory (RAM), it can lead to unresponsive applications, crashes, and general sluggishness. RAM is vital as it allows your system to run programs and processes until they are permanently stored on your local drive.
Thankfully, when you’re grappling with insufficient RAM, there are several steps you can take to fix the problem. From disabling background apps and services to expanding your physical RAM, we’ll walk you through a range of troubleshooting options that won’t break the bank.

Steps to Fix Not Enough Memory Error on Windows 11
1. Disable Background Apps
Many applications run silently in the background, consuming RAM and diminishing resources available to other programs. Disabling these background apps in Windows 11 can significantly benefit your system’s performance, battery life, and connectivity.
To disable background apps on Windows 11:
- Press the Windows key + I to access the Settings menu.
- Click on “Apps” in the left column and select “Installed apps” on the right.

- Search for the app you want to prevent from running in the background.
- Click the three-dot button next to the app and choose “Advanced options” from the menu.

- Scroll down to the “Background apps permissions” section and set “Let this app run in the background” to “Never.”

By following these steps, you can prevent the app from consuming system resources in the background. Repeat this process for any other apps you want to disable.
Please note that for some apps, like Mail & Calendar or OneDrive, you may need to check them manually for updated information.
2. Disable Startup Apps
Disabling startup apps is another way to conserve RAM and optimize system resources. When you prevent apps from launching during startup, your computer will boot faster and run more smoothly.
To disable startup apps using Task Manager:
- Right-click the taskbar and choose “Task Manager” from the menu.

- Click on the “Startup” tab on the left.
- Right-click the app you want to disable during startup and select “Disable.”

Follow these steps for each app you want to exclude from the startup process. Alternatively, you can disable startup apps through the Settings menu.
3. Free Up Storage Space
When your system is low on RAM, Windows uses a page file on your hard drive as virtual memory. However, if your drive is running out of storage space, it can limit virtual memory’s effectiveness. Utilizing the “Storage Sense” feature in Windows 11 is a smart move.
To free up storage space using Storage Sense:
- Open “Settings,” then navigate to “System” and “Storage.”

- Wait for Storage Sense to run and, once it’s complete, select “Temporary files.”

- Choose the file to remove then click “Remove files.”

Additionally, you can free up more space by manually deleting temporary files and emptying the Recycle Bin.
4. Run a Windows Memory Diagnostic Scan
If you’ve recently started experiencing low memory issues, there might be a problem with your RAM. Windows offers a built-in diagnostic tool that can scan your RAM and detect errors. Although it won’t repair errors, it can identify a faulty module that requires reseating or replacement.
To run a Windows Memory Diagnostic scan:
- Press the Windows key + R to open the Run dialog. Type “mdsched” and click “OK” or press “Enter.”

- Choose “Restart now and check for problems (recommended).”

If an error is detected in one of your RAM modules, you can start troubleshooting by reseating it. If this doesn’t resolve the issue, consider seeking professional help, especially if your PC is still under warranty.
5. Increase Physical RAM Capacity
If you’ve exhausted the above options and continue to experience low memory problems, you may need to consider purchasing and installing additional physical RAM.
Conclusion
Solving low memory problems on Windows 11 requires a methodical approach. By following the troubleshooting steps above, you can significantly enhance your system’s performance. Utilize these built-in tools and settings before considering a RAM upgrade. These steps are particularly useful when you encounter slowdowns, system errors, or issues with low memory.
