How to Fix 0x00000027 Error on Windows 11: Step-by-Step Solutions

Encountering the 0x00000027 error on Windows 11 can be frustrating and disruptive. This error usually indicates issues related to system files or hardware problems. Fortunately, there are several straightforward ways to fix this problem step-by-step.

Understanding the causes and following a structured approach will help you resolve the error efficiently. This article will guide you through basic to advanced solutions, ensuring you can get your system back on track.

Take your time with each step and follow the instructions carefully. Most fixes do not require advanced technical knowledge and can be done with built-in Windows tools.

Let’s start by checking some quick notes before diving into the troubleshooting steps.

Quick Note: Prerequisites and Initial Checks

  • Backup Important Data: Before making any changes, back up your important files to an external drive or cloud storage to prevent data loss.
  • Check for Recent Changes: Identify if you recently installed new software, drivers, or hardware which might have triggered the error.
  • Ensure Windows Is Updated: Sometimes, Microsoft releases patches that fix known bugs. Go to Settings > Windows Update and install all pending updates.
  • Note Down Error Details: Write down the exact error message and any related codes to help with troubleshooting or if you need to seek further assistance.

Step 1: Run the System File Checker (SFC) Tool

The 0x00000027 error often relates to corrupted or missing system files. The System File Checker is a built-in Windows tool that scans and repairs system files automatically.

How to run SFC:

  1. Press Windows + S to open the search bar and type cmd.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the Command Prompt window, type the following command and press Enter:
sfc /scannow

This process may take some time to complete. Do not close the window until the verification reaches 100%. If corrupted files are found, the tool will attempt to fix them automatically.

Why this step is important: Fixing system file corruption can resolve many Windows errors, including 0x00000027, without needing more complex methods.

Step 2: Use the Deployment Image Servicing and Management (DISM) Tool

If the SFC tool cannot fix all problems, running the DISM tool is the next step. DISM repairs the Windows image, which helps when system files are severely damaged.

How to run DISM:

  1. Open Command Prompt as administrator again (follow Step 1).
  2. Type the following commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

Each command checks and repairs different aspects of your Windows image. The entire process can take from 10 to 30 minutes depending on your system.

Why this step is important: DISM complements SFC by fixing Windows image issues that SFC alone cannot repair.

Step 3: Check for Disk Errors Using CHKDSK

Sometimes, disk errors or bad sectors on your hard drive can cause the 0x00000027 error. Running the Check Disk tool helps identify and fix these problems.

How to run CHKDSK:

  1. Open Command Prompt as administrator.
  2. Type the following command and press Enter:
chkdsk C: /f /r /x

Explanation of parameters:

  • /f — Fixes errors on the disk
  • /r — Locates bad sectors and recovers readable information
  • /x — Forces the drive to dismount before the scan

You may be prompted to schedule the scan on the next restart since the system drive is in use. Type Y and restart your computer to begin the scan.

Step 4: Update or Roll Back Drivers

Driver conflicts or outdated device drivers can cause system errors like 0x00000027. Checking and updating your drivers can resolve this.

How to update drivers:

  1. Press Windows + X and select Device Manager.
  2. Look for any devices with a yellow warning icon, indicating an issue.
  3. Right-click the device and select Update driver.
  4. Choose Search automatically for updated driver software.

If you recently updated a driver and started facing the error, you can roll back the driver:

  1. In Device Manager, right-click the device and choose Properties.
  2. Go to the Driver tab and click Roll Back Driver.
  3. Follow the on-screen instructions to revert to the previous version.

Why this step matters: Drivers act as a bridge between hardware and software. Ensuring they work correctly prevents many system errors.

Step 5: Perform a Clean Boot

A clean boot starts Windows with only essential services and drivers. This helps identify if background programs are causing the error.

How to perform a clean boot:

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check the box Hide all Microsoft services.
  4. Click Disable all.
  5. Go to the Startup tab and click Open Task Manager.
  6. Disable all startup items listed.
  7. Close Task Manager and click OK in System Configuration.
  8. Restart your computer.

If the error does not occur after a clean boot, it means one of the disabled services or programs is the cause. You can enable them one by one to find the culprit.

Alternative Method: Use System Restore

If you recently started seeing the error and the above steps don’t help, restoring your system to an earlier point might fix the problem.

How to use System Restore:

  1. Press Windows + S, type Create a restore point, and press Enter.
  2. In the System Properties window, click System Restore.
  3. Follow the wizard to choose a restore point dated before the error appeared.
  4. Confirm and allow the system to restart and restore.

Note: System Restore does not affect your personal files but may uninstall recent programs or drivers.
