How to Fix iqvw64e.sys: A Driver Cannot Load on This Device in Windows 11

Arnold K

If you’re seeing a persistent error at startup in Windows 11 that says:

“A driver cannot load on this device: iqvw64e.sys”

you’re dealing with a blocked Intel network driver. This error can be confusing, but it has a clear cause and a reliable fix.

In this guide, you’ll learn:

Let’s dive in.

What Is the iqvw64e.sys Driver?

The file iqvw64e.sys is part of the Intel Ethernet Adapter driver package, typically used by wired network interfaces. It’s a low-level system driver, meaning it loads during startup and interacts closely with Windows networking components.

Why You’re Seeing the “Driver Cannot Load” Error

This error is most commonly triggered by a Windows 11 security feature called Memory Integrity, which blocks untrusted or outdated drivers from loading.

Here’s the breakdown:

While this prevents potential vulnerabilities, it can break legitimate functionality—especially if you rely on older network hardware.

 How to Fix iqvw64e.sys: A Driver Cannot Load on This Device

Here’s a simple, tested fix:

 Step 1: Uninstall the Faulty Driver

  1. Right-click the Start button and choose Device Manager.
  2. In the top menu, click View > Show Hidden Devices.
  3. Expand Network Adapters by clicking the arrow beside it.
  4. Look for any adapter named Intel Network Connection, Intel(R) Ethernet, or similar.
  5. Right-click it and select Uninstall Device.
  6. Repeat for any additional Intel adapters that match.
  7. Confirm the uninstall prompts.

Restart your PC. The error should no longer appear if the driver was the cause.

 Step 2 (Optional but Recommended): Re-Enable Memory Integrity

If you previously disabled Memory Integrity to bypass the error, turn it back on once the faulty driver is removed.

Here’s how:

  1. Go to Start > Settings > Privacy & Security > Windows Security.
  2. Click on Device Security.
  3. Select Core Isolation Details.
  4. Toggle Memory Integrity to ON.
  5. Restart your PC.

Turning it back on helps maintain security against firmware-level threats and malicious drivers.

 Bonus: Update Your Intel Network Drivers

If you still need to use Intel Ethernet hardware, it’s safer to:

Updated drivers are much less likely to trigger security blocks.

 Summary

Cause Fix
Outdated Intel network driver (iqvw64e.sys) Uninstall the driver via Device Manager
Memory Integrity blocks the driver Disable Memory Integrity temporarily, or remove the faulty driver
Need long-term solution Update to signed, official Intel drivers

 Frequently Asked Questions (FAQs)

Q1: What is iqvw64e.sys?

It’s a system driver file used by Intel’s network adapter software, typically for Ethernet (wired) connectivity. It enables low-level communication between your operating system and the network hardware.

Q2: Is it safe to disable Memory Integrity?

Temporarily—yes. Memory Integrity enhances security by preventing malicious or unverified drivers from loading. However, it’s best to turn it back on after removing or updating the problematic driver.

Q3: I’ve uninstalled the driver, but the error still appears. What should I do?

Make sure you:

Q4: Can I reinstall the driver later?

Yes, but only install a digitally signed and updated version from Intel’s official website. Avoid using outdated drivers from third-party sources.

Q5: Does this issue affect Wi-Fi or only Ethernet?

It mainly affects Ethernet (wired) adapters from Intel. However, similar errors can occur with wireless adapters if they use unsupported drivers.

Final Thoughts

While the iqvw64e.sys error might seem intimidating, it’s simply a sign that your system is protecting itself from outdated drivers. By cleaning up these drivers and restoring your system’s built-in security features, you ensure both stability and safety.
