How to Fix Runtime Error 7 Out of Memory on Windows 11: Step-by-Step Solutions

Runtime Error 7 “Out of Memory” on Windows 11 can be frustrating, especially when you are working on important tasks. This error generally means that your computer or the application is running low on available memory. It can interrupt your workflow and cause programs to crash unexpectedly.

Fortunately, there are several straightforward solutions you can try to fix this issue. Some fixes involve freeing up memory, while others require adjusting settings on your PC.

This article will guide you through easy-to-follow steps to resolve Runtime Error 7 systematically and help prevent it from happening again. You don’t need to be a tech expert to follow these solutions.

Let’s get started with some quick checks before diving into detailed fixes.

Quick Note: Prerequisites and Initial Checks

Restart your PC: Sometimes a simple reboot clears temporary memory issues.
Close unnecessary programs: Running many apps at once can consume memory quickly.
Check for enough disk space: Low disk space can affect virtual memory and cause errors.
Update Windows 11: Make sure you have the latest updates installed as they can fix bugs and improve memory management.

Step 1: Free Up Memory by Closing Unnecessary Applications

Running multiple applications simultaneously can exhaust your RAM (Random Access Memory). Closing programs you don’t need will free memory for the application causing the error.

How to do it:

Press Ctrl + Shift + Esc to open the Task Manager.
Click on the Processes tab.
Look for applications with high memory usage.
Select the unnecessary app and click End Task.

By freeing up memory, you reduce the chance of running into the “Out of Memory” error again.

Step 2: Increase Virtual Memory (Paging File) Size

Windows uses virtual memory as an extension of your physical RAM. Increasing the size of the paging file can help when your system runs low on RAM.

To increase virtual memory:

Right-click on the Start button and select Settings.
Go to System > About.
Click on Advanced system settings on the right side.
In the System Properties window, click the Advanced tab.
Under Performance, click Settings.
Go to the Advanced tab again and click Change under Virtual memory.
Uncheck Automatically manage paging file size for all drives.
Select your system drive (usually C:).
Choose Custom size.
Set the Initial size and Maximum size to values recommended by Windows (usually shown at the bottom).
Click Set and then OK.
Restart your computer to apply the changes.

This step helps Windows allocate more disk space as temporary memory, which can prevent runtime errors related to low memory.

Step 3: Scan for Malware and Viruses

Malware can use up your system’s resources without your knowledge. Running a full system scan ensures your PC is clean and memory is not being consumed by harmful software.

How to scan:

Open Windows Security by searching it in the Start menu.
Go to Virus & threat protection.
Click on Scan options and select Full scan.
Click Scan now and wait for the process to finish.

If threats are found, follow the prompts to remove them. A clean system will help reduce memory usage and prevent errors.

Step 4: Update or Reinstall the Affected Application

Sometimes the Runtime Error 7 is caused by bugs or corrupted files within the specific program you are using.

To fix this:

Check if the application has an update available and install it.
If the problem persists, uninstall the app via Settings > Apps > Installed apps.
Restart your PC.
Download and install the latest version from the official website.

This ensures you have a fresh, updated version of the program with fixed bugs and optimized memory use.

Step 5: Adjust System Registry (Advanced)

If you are comfortable making system changes, modifying the Windows registry can sometimes resolve memory errors related to application runtime.

Warning: Editing the registry incorrectly can cause serious problems. Back up your registry before proceeding.

Steps:

Press Win + R, type regedit, and press Enter.
Navigate to the following key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer
Check for any unusual entries related to memory or the problematic program.
You can also increase the SessionViewSize value if present (this is an advanced tweak for some apps).
Close the Registry Editor and restart your PC.

If you are unsure or uncomfortable with this step, it’s best to skip it or consult a professional.
