1. Update the Intel Network Adapter Diagnostic Driver Utility
Let’s start by updating the Intel Network Adapter Diagnostic Driver Utility. Download the driver from the official Intel website to ensure it’s the latest and most suitable version for your system.
2. If Updating Doesn’t Work, Uninstall the Driver
If updating the diagnostic driver doesn’t fix the problem and your internet remains blocked, you may need to uninstall the Intel Network Adapter Diagnostic Driver. After uninstalling the diagnostic driver and restarting the PC, your network adapter should function without issues.
3. Manually Update the Network Adapter Driver
If the previous methods don’t resolve the issue, manually updating your network adapter driver from the official website can prevent the iqvw64e.sys error. This approach updates the crucial driver responsible for network connectivity, resolving compatibility issues and improving stability.
4. Update Windows to the Latest Version
Keeping Windows updated is essential for system stability and security. Issues like “iqvw64e.sys” often arise due to driver incompatibilities, which Microsoft frequently addresses through Windows Updates. These updates include essential security patches, bug fixes, and WHQL-certified drivers to ensure compatibility and performance.
5. Disabling Core Isolation (Caution Needed)
Core Isolation is a security feature in Windows that uses virtualization-based security to isolate critical parts of the operating system, adding an extra layer of protection against malware and other attacks. Memory Integrity, a component of Core Isolation, prevents malicious code from taking advantage of drivers and other low-level programs. However, certain drivers, particularly older or less frequently updated ones like the Intel Network Adapter Diagnostic Driver, may not be compatible with Memory Integrity. This incompatibility can cause the drivers to fail to load, leading to hardware malfunctions or diagnostic errors. Disabling Core Isolation and Memory Integrity might help by allowing the Intel Network Adapter Diagnostic Driver to load without obstruction.
