Resolved: Fix WMI Corrupted in Windows

Table of Contents

Windows Management Instrumentation (WMI) is an important component of the Windows operating system. It’s a framework that provides a unified interface for Windows components to interact with the system.

It’s like a control panel under the hood of your computer.

When WMI works well, you likely won’t notice it. But if it gets corrupted, it can lead to many issues:

  • application errors
  • system slowdowns
  • Blue Screens of Death.

This guide will walk you through why WMI gets corrupted and various solutions to fix it, all broken down in an easily digestible manner.

Why Does WMI Get Corrupted?

WMI corruption can occur for a long list of reasons, but most common are:

  • faulty Windows updates (I have problems with any single Patch Tuesday)
  • malware intrusion
  • file corruption

A corrupted WMI can render your system virtually helpless, affecting anything from your system’s security protocols to its fundamental functionalities. The forum threads here offer deep insights into some real-life examples of WMI corruption.

How to Fix WMI Corruption in Windows

Repairing WMI can range from beginner-friendly solutions to advanced maneuvers. I have researched multiple solutions and tried to perform them on my laptop and observed that some are way easier to perform for a regular user. Let’s start with the easy ones and move up the complexity ladder.

Run the Windows Troubleshooter

The built-in Windows Troubleshooter is the first line of defense against many system-related issues, including WMI corruption. While it’s not a magic wand, it’s often effective enough to resolve minor issues by resetting services or updating configurations.

  1. Open Settings
    • Press Windows key + I to open Settings.
  2. Navigate to Update & Security
    • Click on Update & Security.
  3. Launch Troubleshooter
    • Click on Troubleshoot, followed by Additional troubleshooters.
    • Locate Windows Management Instrumentation and click Run the troubleshooter.
  4. Follow the Prompts
    • Observe the on-screen instructions and let the tool attempt to fix the issues.

Restart the WMI Service

Restarting the WMI service manually can sometimes clear the corruption. This action essentially turns off and turns on the WMI, which can automatically correct any minor glitches or bugs causing the issue.

  1. Open Run Dialog
    • Hit Windows key + R.
  2. Type Services.msc
    • Type services.msc and hit Enter.
  3. Locate WMI Service
    • Scroll to find Windows Management Instrumentation, right-click and select Restart.

Rebuild WMI Repository

If your WMI repository itself is corrupted, rebuilding it can resolve underlying issues. However, this method should be exercised with caution as it will reset your WMI configuration to the system defaults.

  1. Open Command Prompt as Administrator
    • Search for Command Prompt, right-click and select Run as administrator.
  2. Run Commands
    • Type winmgmt /resetrepository and hit Enter.
  3. Reboot Your PC
    • Restart your computer to complete the reset.

Use Third-Party WMI Repair Tools

Some third-party tools are built specifically to tackle WMI corruption. One such reputable tool can be found here. Using a third-party tool can automate the repair process and is especially useful if you’re not comfortable tinkering with system settings.

  1. Download the Tool
    • Visit the site via the link and download the tool.
  2. Run the Application
    • Double-click the downloaded file.
  3. Follow Instructions
    • Follow the on-screen instructions to repair WMI.

Perform a System Restore

Performing a system restore can roll your system settings back to a point when WMI was functioning correctly. This method is like a time machine for your system but should be used judiciously.

  1. Open Run Dialog
    • Press Windows key + R.
  2. Execute System Restore
    • Type rstrui.exe and hit Enter.
  3. Follow On-Screen Instructions
    • Choose a system restore point prior to the onset of the corruption and follow the prompts.

Repair Windows Installation

Repairing your Windows installation is the nuclear option. It should only be used when all else fails and you’ve backed up your crucial data. This will essentially re-install Windows while keeping your personal files intact, but it’s the most time-intensive option.

  1. Back Up Your Data
    • Backup all important data to an external drive.
  2. Insert Installation Media
    • Insert the Windows installation disk or USB drive.
  3. Reboot and Select Boot Option
    • Reboot your computer and select to boot from the installation media.
  4. Follow Repair Instructions
    • Opt for “Repair your computer” and follow the subsequent instructions.


Fixing WMI corruption can be a daunting task, especially if you’re not tech-savvy. But with this guide, you have a roadmap of solutions that are both efficient and feasible. Whether you’re a beginner or an expert, these steps can guide you towards restoring your system’s health.
