How to Fix Error 0x800700e1 on Windows Step by Step

Encountering error 0x800700e1 on a Windows system can be a frustrating experience, especially when you’re in the middle of critical operations such as copying files, system backup, or running Windows updates. This error typically signals that Windows is blocking a file operation because it suspects the presence of a virus or malicious software.

While the cause of this issue may vary, it’s crucial to address it promptly to avoid potential performance lags, failed backups, or even data corruption. In this step-by-step guide, we’ll walk you through the most reliable solutions to fix error 0x800700e1 and get your system running smoothly again.

What Is Error 0x800700e1?

Error code 0x800700e1 is often accompanied by the message: The operation did not complete successfully because the file contains a virus or potentially unwanted software. This normally occurs during system backups, file transfers, or when using third-party software that interacts deeply with the operating system. Windows Defender or another antivirus solution flags the file or action as dangerous and aborts the operation.

Although the message suggests a security concern, the file may be perfectly safe—hence it’s essential to determine whether the alert is valid or a false positive.

Common Causes of Error 0x800700e1

• Presence of actual malware or viruses on the system
• False positives by antivirus software
• Corrupted system files
• Improper system settings or permissions
• Third-party software conflicts

Step-by-Step Guide to Fix Error 0x800700e1

Below are several tried-and-tested solutions to fix this error. It’s a good practice to follow these steps in order to eliminate the most likely causes first.

Step 1: Run a Full-System Virus Scan

Since the error message often points to suspicion of malware, your first task should be to perform a comprehensive malware scan.

1. Open Windows Security by clicking the Start menu and typing Windows Security.
2. Click on Virus & threat protection.
3. Click Scan options and select Full scan.
4. Click Scan now and let the process complete, which might take a while.

If any threats are detected, make sure to quarantine or remove them accordingly. Reboot the system after the scan completes.

Step 2: Temporarily Disable Windows Defender or Antivirus Software

If you are confident that the file involved is legitimate and poses no threat, try temporarily disabling your antivirus, including Windows Defender. This step can help determine if the antivirus is causing a false positive.

1. Open Windows Security.
2. Click Virus & threat protection > Manage settings.
3. Turn off Real-time protection.

Important: Only attempt this if you are absolutely sure the file is safe. We strongly recommend turning real-time protection back on after testing.

Step 3: Add the File or Folder to Exclusions

If you determine that the file is important and safe but still gets flagged, you can add an exclusion in Windows Defender temporary to bypass the error.

1. Go to Windows Security > Virus & threat protection.
2. Click Manage settings under Virus & threat protection settings.
3. Scroll down and click Add or remove exclusions.
4. Click Add an exclusion and choose File or Folder.
5. Browse and select the troubled file or folder.

This ensures Windows Defender doesn’t interfere with that specific file again. However, be cautious with what you exclude.

Step 4: Perform a Clean Boot

Third-party software or services might be interfering with your system processes. Conducting a clean boot helps run Windows with only essential processes.

1. Press Windows + R, type msconfig, and press Enter.
2. Go to the Services tab and check Hide all Microsoft services, then click Disable all.
3. Now go to the Startup tab and click Open Task Manager.
4. Disable all startup programs listed.
5. Restart your computer.

Try performing the operation that was failing earlier and see if the issue persists.

Step 5: Use Windows System File Checker (SFC) and DISM

Corrupted operating system files can also raise the 0x800700e1 error. Use SFC and DISM tools to repair them.

1. Open the Command Prompt as Administrator.
2. Type the following command and press Enter:
   sfc /scannow
3. Wait until the scan completes and follow any on-screen instructions.
4. Then run the next command:
   DISM /Online /Cleanup-Image /RestoreHealth

Both tools combined can handle a range of background issues that could be triggering the error.

Step 6: Check for Windows Updates

Running an outdated version of Windows can result in compatibility issues and system errors. Make sure your operating system is up to date.

1. Go to Settings > Windows Update.
2. Click Check for updates.
3. Download and install any available updates.

Once updates are applied, reboot your system and reattempt the operation.

Step 7: Use an Alternative Backup or File Handling Tool

If you’re encountering the error while backing up files, using an alternative backup utility may help. Microsoft’s built-in tools can sometimes be overly cautious.

Consider using third-party backup solutions like:

• Acronis True Image
• Macrium Reflect
• EaseUS Todo Backup

These tools often offer better customization and may bypass the internal Windows error triggers.

When All Else Fails: Restore or Reset Windows

If none of the above steps resolve the 0x800700e1 error, you may consider restoring your system to an earlier state using System Restore.

1. Type System Restore in the Start menu and select Create a restore point.
2. Under the System Protection tab, click System Restore.
3. Follow the on-screen prompts to select a restore point prior to when the error started.

If the issue started recently, this can effectively roll back problematic changes. As a last option, a Windows reset or clean installation might be necessary, but that should only happen after exhausting all other options.

Final Thoughts

Error code 0x800700e1 can look intimidating and serious—and sometimes it is. But in many cases, it stems from overprotective antivirus filters or corrupted system files. With careful diagnosis and methodical application of the steps outlined above, you can correct the problem without compromising your system’s safety or functionality.

Always remember to back up important data and proceed cautiously when making system-level changes. If you’re unsure about disabling antivirus protections or making complex system adjustments, consider consulting professional IT support.

Handled correctly, error 0x800700e1 is entirely fixable, and your system can be restored to full operational health with peace of mind.
