How to Fix “Windows Cannot Access the Specified Device” Error in Windows 11: Complete Troubleshooting Steps

If you see the error message “Windows cannot access the specified device” on your Windows 11 PC, it means the system is having trouble opening a file, folder, or program. This can be frustrating, especially if you need the item urgently.

Fortunately, there are several simple steps you can follow to fix this issue. These steps cover common causes like permissions, security settings, and corrupted shortcuts.

This guide will walk you through easy-to-understand troubleshooting methods, starting with the simplest and moving to more advanced solutions.

By the end, you should be able to regain access to your files or programs without any hassle.

Quick Note: Prerequisites and Basic Checks

Before diving into detailed fixes, make sure to do these quick checks:

  • Confirm you are logged in as an administrator or have the necessary permissions.
  • Check if the file or program is on an external drive or network location that is currently connected.
  • Make sure your antivirus isn’t blocking the file or program.
  • Try restarting your computer to clear temporary glitches.

These basic steps can often resolve the problem instantly or help identify a more specific cause.

Step 1: Check File or Folder Permissions

One common reason for this error is insufficient permission to access the file or folder. Windows restricts access to protect your system and data.

Follow these steps to check and modify permissions:

  1. Right-click the file or folder that shows the error and select Properties.
  2. Go to the Security tab.
  3. Click on your user account name under Group or user names.
  4. Look at the permissions below. If Read and Read & execute are unchecked, you need to change this.
  5. Click Edit and then check the boxes for Read and Read & execute.
  6. Click Apply and then OK.

Trying to access the file again should now work if permission was the issue.

Step 2: Unblock the File

If you downloaded the file from the internet, Windows might block it for security reasons. Unblocking it can solve the problem.

Here’s how to unblock a file:

  1. Right-click the file and select Properties.
  2. In the General tab, look for a checkbox or button labeled Unblock near the bottom.
  3. If you see it, check the box or click Unblock.
  4. Click Apply and then OK.

This removes the security block placed by Windows and may allow access.

Step 3: Disable Your Antivirus Temporarily

Sometimes, antivirus programs mistakenly block legitimate files or programs. Temporarily disabling your antivirus can help identify if it is causing the issue.

Important: Only do this if you trust the file or program completely.

  1. Find your antivirus icon in the system tray (bottom-right corner).
  2. Right-click the icon and look for an option to disable or turn off protection temporarily.
  3. Choose a short time period, such as 10 or 15 minutes.
  4. Try opening the file or program again.
  5. If it works, add the file or program to the antivirus’s whitelist or exceptions.
  6. Remember to re-enable your antivirus as soon as possible.

Step 4: Check the Shortcut or File Path

If you are opening the file or program via a shortcut, the shortcut itself may be broken or pointing to a wrong location.

To fix this:

  1. Right-click the shortcut and select Properties.
  2. Look at the Target field under the Shortcut tab.
  3. Make sure the path points to the correct file location.
  4. If the file has been moved or deleted, you need to update the path or recreate the shortcut.

Opening the file directly from its original folder (without using the shortcut) can also test if the shortcut is the problem.

Step 5: Run the File or Program as Administrator

Some files or programs need elevated permissions to run properly. Running them as an administrator can help.

Here’s how:

  1. Right-click the file or program.
  2. Select Run as administrator.
  3. If prompted by User Account Control (UAC), click Yes to allow.

If this works, you can set the program to always run as administrator by adjusting its properties.

Step 6: Check for Network or Drive Access Issues

If your file or program is stored on an external drive or network location, make sure:

  • The drive is properly connected and powered on.
  • You have the necessary network permissions.
  • The network location is accessible (try opening it in File Explorer).

Sometimes, reconnecting the drive or network can solve the issue.

Advanced Options

Use the System File Checker (SFC) Tool

Corrupted system files can cause access problems. The System File Checker can scan and repair them.

To run SFC:

  1. Press Windows + S, type cmd, then right-click Command Prompt and choose Run as administrator.
  2. In the black command window, type sfc /scannow and press Enter.
  3. Wait for the scan to complete. It may take some time.
  4. If issues are found, the tool will attempt to fix them automatically.

Create a New User Profile

If the problem persists, it might be related to your user account. Creating a new user account can help isolate this.

Steps:

  1. Open Settings by pressing Windows + I.
  2. Go to Accounts > Family & other users.
  3. Click Add account under Other users.
  4. Follow the prompts to create a new local user.
  5. Log out and sign in with the new user, then try accessing the file or program again.
