How to Fix “Insufficient System Resources to Complete the Requested Service” Error on Windows 11

If you have encountered the error message “Insufficient System Resources to Complete the Requested Service” on your Windows 11 PC, it can be frustrating. This error usually happens when your system runs low on memory or other critical resources. It can prevent you from opening files, running applications, or performing certain tasks.

Fortunately, there are several simple ways to fix this problem. Most of these solutions involve freeing up system resources or adjusting Windows settings. You don’t need to be an expert to try them.

In this guide, we will walk you through easy steps to resolve this error. Each solution is explained as clearly as possible, so you can follow along without confusion.

By the end, you should have your system running smoothly again.

Quick Note Before You Begin

  • Make sure your Windows 11 is up to date. Sometimes updates fix system bugs.
  • Close any unnecessary programs before troubleshooting to free up memory.
  • Save any important work because some steps may require restarting your PC.
  • If you are using an older or low-spec computer, some fixes may take longer to complete.

Step 1: Restart Your Computer

Restarting your PC is the easiest and fastest way to free up system resources. When you reboot, Windows clears temporary files and closes background processes that might be using memory.

To restart:

  1. Click on the Start button in the bottom-left corner.
  2. Select the Power icon.
  3. Click Restart.

After your PC restarts, check if the error still appears. If yes, move on to the next step.

Step 2: Close Unnecessary Background Applications

Many applications run in the background without you noticing. These apps consume memory and system resources, which can trigger this error.

To close them:

  1. Press Ctrl + Shift + Esc to open the Task Manager.
  2. Go to the Processes tab.
  3. Look for apps listed under Apps or Background processes that you don’t need right now.
  4. Select the app and click End task.

Be careful not to close processes related to Windows system operations.

Step 3: Increase Virtual Memory (Paging File)

Windows uses virtual memory (paging file) to supplement your physical RAM. Increasing the size of the paging file can help if your system runs out of RAM.

Here is how to adjust virtual memory:

  1. Press Windows + S, type Advanced system settings, and open it.
  2. In the System Properties window, go to the Advanced tab.
  3. Under Performance, click on Settings.
  4. In the new window, go to the Advanced tab.
  5. Click on Change under Virtual memory.
  6. Uncheck Automatically manage paging file size for all drives.
  7. Select your system drive (usually C:).
  8. Choose Custom size and enter values for Initial size and Maximum size. A good rule is to set both to 1.5 to 3 times your installed RAM in megabytes.
  9. Click Set, then OK to save changes.
  10. Restart your computer to apply new settings.

Increasing virtual memory helps Windows manage tasks that require more memory than physically available.

Step 4: Run the System File Checker (SFC) Tool

Corrupted system files can cause resource errors. The System File Checker tool scans and repairs these files.

To run SFC:

  1. Press Windows + S, type cmd, right-click on Command Prompt, and select Run as administrator.
  2. In the black Command Prompt window, type the following command and press Enter:
sfc /scannow

The scan may take some time. Once finished, it will report if any corrupted files were fixed.

Restart your PC and check for the error again.

Step 5: Check for Malware and Viruses

Malware can consume system resources and cause errors. Running a full system scan is important.

You can use Windows Security:

  1. Press Windows + I to open Settings.
  2. Go to Privacy & Security > Windows Security.
  3. Click Virus & threat protection.
  4. Select Quick scan or Full scan for a deeper check.

If threats are found, follow the recommended actions to remove them.

Alternative and Advanced Options

Adjust Registry Settings (For Advanced Users)

Sometimes, Windows registry settings related to system resource limits can cause this error. Modifying the registry can help, but it should be done carefully.

To try this:

  1. Press Windows + R, type regedit, and press Enter.
  2. Navigate to:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management
  1. Look for PagedPoolSize and NonPagedPoolSize. If they don’t exist, you can create new DWORD values.
  2. Set these values to ffffffff (hexadecimal) to allow Windows to manage pool sizes automatically.
  3. Close the registry editor and restart your PC.

Note: Editing the registry incorrectly can cause serious issues. Always back up your registry before making changes.

Check Hardware Health

If the problem persists, it might be related to faulty RAM or other hardware issues. Running hardware diagnostics or using tools like Windows Memory Diagnostic can help identify problems.

To run Windows Memory Diagnostic:

  1. Press Windows + S, type Windows Memory Diagnostic, and open it.
  2. Choose Restart now and check for problems.
  3. Your computer will restart and run tests. Results will appear after you log back in.
