This issue commonly appears on systems with ASUS hardware utilities (like AI Suite, Aura, or Armory Crate) that use the AsIO.sys driver. Typically, this problem occurs because the AsIO.sys driver either:
lacks the necessary security certifications ordoes not comply with the latest Windows security standards.
These factors cause it to be flagged as incompatible or unsafe. In this guide, we will show you ways to resolve this error.
1. Update the ASUS Application
Updating the ASUS application, such as Armoury Crate, ensures that all its components, including the AsIO.sys driver, are updated according to the latest security protocols and system requirements. By keeping your applications current, you decrease the chance of encountering errors caused by outdated or unsupported drivers. Below, we’ll show you how to update Armoury Crate. You can use similar steps to update other ASUS applications.
2. Remove AsIO.sys File
If you no longer require ASUS utilities, removing AsIO.sys is the most straightforward solution. This driver is primarily used by ASUS software (e.g., AI Suite, Aura Sync) to interact with system sensors. However, if it’s outdated or not needed, Windows security might block it, causing the error. By deleting it, you stop Windows from loading a problematic driver on startup.
3. Disable Microsoft’s Vulnerable Driver Block List
Windows 10/11 security features, including Memory Integrity (Core Isolation) and the Microsoft Vulnerable Driver Blocklist, are designed to prevent outdated or potentially harmful drivers from loading. AsIO.sys might be flagged because it uses old driver signing methods or has security issues. Note: This method immediately resolves the error but reduces security, meaning it should be used as a last-resort option. If ASUS releases an updated driver, be sure to re-enable these settings for continued protection.
