Troubleshooting MIC (Mandatory Integrity Control) Not Working on Windows 10




Mandatory Integrity Control (MIC) is a fundamental security feature in Windows 10 designed to enforce strict access controls and protect system integrity. When MIC is not functioning correctly, it can compromise the security posture of the system. This article explores common issues causing MIC to malfunction on Windows 10, troubleshooting steps to resolve these issues, and best practices to ensure MIC operates effectively for enhanced system security.

Understanding MIC in Windows 10

MIC operates by assigning integrity levels to securable objects such as files, registry keys, processes, and threads. These integrity levels range from Low to High, with each level dictating access permissions and interactions between different entities within the system. MIC prevents unauthorized access and ensures data protection by restricting processes to their designated integrity levels. This is common issue that mic not working windows 10.

Common Issues with MIC Not Working

Misconfigured Security Policies: Incorrectly configured Group Policy settings or security policy configurations can prevent MIC from enforcing access controls effectively.

Corrupted System Files: System file corruption or misconfigured system settings may interfere with MIC’s ability to assign and enforce integrity levels.

Malware or Security Software Interference: Certain malware or security software may conflict with MIC settings, causing it to malfunction or disable certain security features.

Troubleshooting MIC Issues on Windows 10

To diagnose and resolve MIC issues effectively, follow these troubleshooting steps:

Step 1: Verify MIC Settings

Access Local Security Policy: Press Win + R, type secpol.msc, and press Enter to open Local Security Policy.

Navigate to Security Options: Expand Security Settings > Local Policies > Security Options and verify settings related to User Account Control (UAC) and MIC.

Ensure MIC Policies Are Enabled: Check that MIC policies such as “User Account Control: Admin Approval Mode for the Built-in Administrator account” and “User Account Control: Run all administrators in Admin Approval Mode” are set to enabled.

Step 2: Check for Malware

Use Windows Security: Open Windows Security from the Start menu, select Virus & threat protection, and run a full scan to detect and remove any malware that may be interfering with MIC.

Use Third-Party Antivirus: If using third-party antivirus software, ensure it is updated to the latest version and perform a full system scan.

Step 3: Update Windows and Drivers

Check for Windows Updates: Go to Settings > Update & Security > Windows Update and check for any pending updates. Install them and restart your computer.

Update Device Drivers: Outdated or incompatible device drivers can cause MIC issues. Update drivers through Device Manager or download them from the manufacturer’s website.

Step 4: Restore System Health

Best Practices for MIC Management

To ensure MIC functions properly and enhances system security:

Regular Maintenance: Perform regular system maintenance, including updating software and drivers, and scanning for malware.

Monitor MIC Events: Use event logs and monitoring tools to track MIC-related events and identify any anomalies or security incidents.

Educate Users: Educate users on the importance of MIC and best practices for maintaining system security.


Addressing MIC issues on Windows 10 requires systematic troubleshooting to identify and resolve underlying causes such as misconfigurations, system file corruption, or compatibility issues. By following the outlined steps and best practices, administrators can restore MIC functionality and strengthen the overall security posture of their Windows 10 systems.

In summary, troubleshooting MIC not working involves verifying settings, running diagnostic scans, checking for malware, updating system components, and implementing best practices to ensure effective enforcement of access controls and data protection mechanisms in Windows 10.
