Quick Note: Prerequisites and Checks Before You Begin

Before trying any fixes, make sure to check these points:

• Stable Internet Connection: Some fixes require downloading files or updates.
• Enough Disk Space: Ensure your drive has sufficient free space to avoid file corruption.
• Backup Important Files: Always back up your data to prevent accidental loss during troubleshooting.
• Windows Updates: Confirm your Windows 11 is up to date, as updates often fix known bugs.

Step 1: Run the Windows Troubleshooter

The Windows Troubleshooter is a built-in tool that detects and fixes common system errors automatically.

1. Click on the Start button and select Settings.
2. Go to System > Troubleshoot > Other troubleshooters.
3. Find the troubleshooter relevant to your issue, such as File and Folder troubleshooter (if available).
4. Click Run and follow the on-screen instructions.

This step helps fix minor file and system glitches that might be causing the error.

Step 2: Clear the Windows Update Cache

If the error occurs during Windows updates or file downloads, clearing the update cache can help. Corrupted cache files may cause hash mismatch errors.

1. Press Windows + R to open the Run dialog box.
2. Type services.msc and press Enter.
3. In the Services window, scroll down and locate Windows Update.
4. Right-click it and select Stop.
5. Open File Explorer and navigate to C:WindowsSoftwareDistributionDownload.
6. Delete all files and folders inside the Download folder.
7. Go back to the Services window, right-click Windows Update and select Start.

Clearing the cache removes corrupted files and forces Windows to download fresh copies.

Step 3: Use the System File Checker (SFC) Tool

The System File Checker scans for corrupted or missing system files and repairs them automatically.

1. Press Windows + S, type cmd, right-click Command Prompt and select Run as administrator.
2. In the command window, type the following and press Enter:

sfc /scannow

The scan can take some time. Once completed, it will inform you if any repairs were made.

Running SFC is important because corrupted system files often cause errors like 0x80091007.

Step 4: Run the Deployment Image Servicing and Management (DISM) Tool

If SFC doesn’t fix the problem, DISM can repair the Windows image, which can fix deeper system issues.

1. Open Command Prompt as administrator as explained in Step 3.
2. Type each command below one by one and press Enter after each:

DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

Wait for each process to complete. This might take several minutes.

DISM helps by downloading healthy files from Microsoft servers and replacing damaged files on your PC.

Step 5: Rename or Delete the Problematic File

Sometimes, the error appears due to a specific corrupted file. Renaming or deleting that file allows Windows to recreate it.

To identify and fix this:

• Note the file name mentioned in the error message (if available).
• Navigate to the file’s location using File Explorer.
• Right-click the file and select Rename. Add .old at the end of the file name.
• If renaming is not possible, carefully delete the file.
• Restart your computer and check if the error persists.

This step forces Windows to replace the corrupted file with a fresh copy.

Alternative Method: Use a Third-Party File Repair Tool

If manual methods don’t work and the error relates to corrupted files you need to recover, consider using trusted third-party file repair software.

These tools can scan and repair damaged files that Windows utilities might miss. Always download from reputable sources and scan for malware before use.
