Understanding Windows 10 Security and Quarantined Files
Windows 10 Security, also known as Windows Defender, is a built-in security suite that protects your computer from various threats, including viruses, malware, and other types of malicious software. When Windows 10 Security detects a potentially malicious file, it quarantines the file to prevent it from causing harm to your system. Quarantined files are isolated from the rest of your system, and they cannot be accessed or executed until they are removed or restored.
Why Remove Quarantined Files?
Removing quarantined files is essential to maintaining your system’s security and performance. Quarantined files can occupy valuable disk space, and if they are not removed, they can accumulate over time, leading to decreased system performance. Additionally, quarantined files can still pose a threat to your system if they are not properly removed.
Methods for Removing Quarantined Files
There are two primary methods for removing quarantined files from Windows 10 Security: using the Windows Defender app and using the Command Prompt.
Method 1: Using the Windows Defender App
- Open the Windows Defender app by searching for “Windows Defender” in the Start menu.
- Click on the “Virus & threat protection” tab.
- Click on the “Threat history” tab.
- Click on the “Quarantined items” tab.
- Select the files you want to remove and click on the “Remove” button.
- Confirm that you want to remove the selected files by clicking on the “Yes” button.
Method 2: Using the Command Prompt
Using the MpCmdRun.exe Command
The MpCmdRun.exe command is a powerful tool that allows you to manage Windows Defender from the Command Prompt. To remove quarantined files using the MpCmdRun.exe command, follow these steps:
- Open the Command Prompt as an administrator by right-clicking on the Start button and selecting “Command Prompt (Admin)”.
- Type the following command and press Enter:
MpCmdRun.exe -Restore -ListAll - This will display a list of all quarantined files. Take note of the file names and their corresponding IDs.
- To remove a specific file, type the following command and press Enter:
MpCmdRun.exe -Remove -FileId <ID>Replace<ID>with the ID of the file you want to remove. - To remove all quarantined files, type the following command and press Enter:
MpCmdRun.exe -Remove -All
Troubleshooting Common Issues
When removing quarantined files, you may encounter some common issues. Here are some troubleshooting tips to help you resolve these issues:
Issue 1: Unable to Remove Quarantined Files
If you are unable to remove quarantined files, it may be due to a lack of administrative privileges. To resolve this issue, try running the Windows Defender app or the Command Prompt as an administrator.
Issue 2: Quarantined Files Are Not Displayed
If quarantined files are not displayed in the Windows Defender app or the Command Prompt, it may be due to a corrupted Windows Defender database. To resolve this issue, try resetting the Windows Defender database by typing the following command in the Command Prompt: MpCmdRun.exe -Reset
Best Practices for Managing Quarantined Files
To maintain your system’s security and performance, it is essential to manage quarantined files effectively. Here are some best practices to follow:
Regularly Review Quarantined Files
Regularly review quarantined files to ensure that they are not accumulating over time. Remove any files that are no longer needed or that pose a threat to your system.
Use the Windows Defender App
The Windows Defender app provides a user-friendly interface for managing quarantined files. Use the app to review and remove quarantined files, rather than relying on the Command Prompt.
Keep Your System Up-to-Date
Keeping your system up-to-date with the latest security updates and patches is essential to preventing malware infections. Regularly update your system to ensure that you have the latest security features and protections.

By using the Windows Defender app or the Command Prompt, you can easily remove quarantined files and prevent them from accumulating over time. Remember to regularly review quarantined files, use the Windows Defender app, and keep your system up-to-date to ensure that your system remains secure and performing optimally.
By following the steps and best practices outlined in this article, you can effectively manage quarantined files and maintain your system’s security and performance.
What are quarantined files in Windows 10 Security, and why are they isolated?
Quarantined files in Windows 10 Security are files that have been identified as potentially malicious or infected with malware by the operating system’s built-in security software, Windows Defender. When a file is detected as suspicious, Windows Defender isolates it to prevent any potential harm to the system. This isolation process is known as quarantining.
The primary purpose of quarantining files is to prevent them from causing any damage to the system or spreading malware to other files. By isolating these files, Windows Defender allows users to review and take action on them, either by removing or restoring them, depending on their legitimacy and importance.
How do I access quarantined files in Windows 10 Security?
To access quarantined files in Windows 10 Security, you need to open the Windows Security app. You can do this by searching for “Windows Security” in the Start menu or by typing “windowsdefender:” in the Run dialog box (Windows key + R). Once the app is open, click on the “Virus & threat protection” tab on the left side of the window.
In the “Virus & threat protection” tab, click on the “Protection history” link. This will take you to a page that displays a list of all the quarantined files on your system. From here, you can view the details of each file, including its name, location, and the reason it was quarantined.
What are the risks of removing quarantined files from Windows 10 Security?
Removing quarantined files from Windows 10 Security can pose some risks to your system’s security. If a quarantined file is actually malicious, removing it could allow the malware to spread and cause harm to your system. Additionally, if the file is a legitimate system file that has been infected, removing it could cause system instability or crashes.
On the other hand, if a quarantined file is a false positive (i.e., a legitimate file that was mistakenly identified as malicious), removing it could resolve any issues related to the file’s functionality. However, it’s essential to exercise caution when removing quarantined files and to carefully review the file’s details before taking any action.
How do I remove quarantined files from Windows 10 Security?
To remove quarantined files from Windows 10 Security, open the Windows Security app and navigate to the “Virus & threat protection” tab. Click on the “Protection history” link, and then select the quarantined file you want to remove. Click on the “Actions” dropdown menu next to the file and select “Remove” or “Delete”.
Alternatively, you can also remove quarantined files using the Windows Defender PowerShell module. To do this, open PowerShell as an administrator and run the “Remove-MpThreat” cmdlet, followed by the ID of the quarantined file you want to remove. You can find the ID of the file in the Windows Security app or by running the “Get-MpThreat” cmdlet.
Can I restore quarantined files in Windows 10 Security?
Yes, you can restore quarantined files in Windows 10 Security. To do this, open the Windows Security app and navigate to the “Virus & threat protection” tab. Click on the “Protection history” link, and then select the quarantined file you want to restore. Click on the “Actions” dropdown menu next to the file and select “Restore” or “Allow”.
Restoring a quarantined file will move it back to its original location on your system. However, keep in mind that restoring a malicious file can pose a risk to your system’s security. Before restoring a quarantined file, make sure you have verified its legitimacy and safety.
How can I prevent files from being quarantined in Windows 10 Security?
To prevent files from being quarantined in Windows 10 Security, you can add them to the Windows Defender exclusion list. To do this, open the Windows Security app and navigate to the “Virus & threat protection” tab. Click on the “Manage settings” link under “Virus & threat protection settings”, and then scroll down to the “Exclusions” section.
In the “Exclusions” section, click on the “Add or remove exclusions” link, and then select the file or folder you want to exclude from scanning. You can also specify the type of exclusion, such as a file extension or a specific process. By excluding a file or folder, you can prevent Windows Defender from scanning it and potentially quarantining it.
What happens to quarantined files when I reset Windows 10?
When you reset Windows 10, all quarantined files are deleted. The reset process removes all installed apps, settings, and files, including those that have been quarantined by Windows Defender. This means that any quarantined files will be permanently deleted and will not be recoverable.
If you want to keep any quarantined files, you should restore them before resetting Windows 10. Alternatively, you can back up the files to an external drive or cloud storage service before resetting the operating system. This will allow you to recover the files later if needed.
