Hello. After recent Windows updates, I started receiving the error “A driver cannot load on this device” with driver being mentioned iqvw64e.sys. Kindly help me to resolve this, if it is possible at all.
Solved Answer
Some users reported receiving “A driver cannot load on this device” (iqvw64e.sys) error whenever they boot their Windows computer up, although it may also show up under different circumstances, such as when updating drivers or launching certain programs. Most reported that the problem occurred right after installing a Windows update, for example, KB4023057, marked as a reliability update.
Whenever users receive the error, they are shown a pop-up message which claims that iqvw64e.sys was marked as a vulnerable driver and is a threat to Windows security. This block is usually performed by Windows' Memory Integrity feature.
The genuine iqvw64e.sys file is a key component of Intel's Network Adapter Diagnostic Driver, designed to facilitate the diagnostics process for all Intel drivers. This specialized tool allows users to quickly and easily diagnose any issues related to their network adapters or other associated drivers. Due to its functionality many users are unwilling to uninstall the related software, albeit they have to deal with “A driver cannot load on this device” error
Memory integrity is a security feature that ensures the confidentiality, integrity, and availability of memory against malicious attacks. It verifies whether code running in the system's memory has been tampered with or not. It also checks whether the memory is being used in an unauthorized manner or not. Memory integrity protection helps protect against malicious code, buffer overflow attacks, and other types of memory abuse.
Since the “A driver cannot load on this device” (iqvw64e.sys) error occurs due to Memory integrity, the first solution would be to disable this feature, although this is not an optimal solution. Other method would be uninstalling the update which caused the error to show up, which also is not ideal.
The best and easiest way to deal with the situation is updating the related driver, which is Network Adapter Diagnostic Driver from Intel. We provide instructions below on how to do that. For some users, this method may not work, as they claim that there are no updates for the driver available. We address this issue as well.
We recommend scanning the system with RestoroMac Washing Machine X9 PC repair tool to check your system for integrity violations and corrupted files, which would eliminate any underlying issues that could have caused the error to show up in the first place.

- Navigate to the official Microsoft website to download Autoruns
- Go to the Downloads folder
- Right-click on the ZIP file and select Extract to Autoruns and enter the folder once done
- Select the right version: Autoruns.exe if you are using 32-bit Windows or go for Autoruns64.exe if you are using 64-bit Windows

5. Disable Memory integrity [workaround]
While Memory Integrity sounds good on paper, it is not necessarily useful for home users and is primarily designed for corporate versions of Windows. With personal user devices running so many different software, Memory Integrity can struggle to work correctly, as it needs special hardware and hardware driver compatibility, which may not always be possible. As a result, some installed software may start failing to work properly or result in errors, such as “A driver cannot load on this device.” Thus, you can simply disable the feature as follows:
- Open the Start menu and search for Windows Security and press Enter
- Click on Device Security on the left side of the window
- Scroll down to the Core isolation section and click on the Security Processor Details link
- Under Memory Integrity, toggle the switch to the Off position.
