What Is Windows Error Code ERROR_146?
Before diving into the fix, it’s helpful to understand what ERROR_146 means. This error commonly appears when your computer runs into a resource conflict, often related to network connections or device drivers. It may prevent proper network communication or hardware function, displaying messages such as:
- "ERROR_146: Cannot open device or resource busy"
- "Resource is currently in use"
This is a sign that a system process or application is holding onto a resource that another process needs, causing a conflict.
Causes of Windows Error Code ERROR_146
- Network adapter issues (device conflicts or improper driver installation)
- Software conflicts where multiple programs try to use the same network resource
- Background processes or services blocking access to a resource
- Corrupted or outdated drivers
- Malware or virus infections interfering with system functionality
Step-by-Step Guide to Fix ERROR_146
Step 1: Restart Your Computer
This is often the simplest yet most effective fix. A restart clears temporary resource locks and refreshes system processes.
- Save all your work.
- Click on Start > Power > Restart.
- After rebooting, check if the error still appears.
Pro tip: A restart resolves many minor conflicts and glitches—always try this first!
Step 2: Identify and Close Conflicting Processes
Sometimes, certain applications or services keep resources busy.
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Processes tab.
- Look for processes that might be using network or device resources heavily (e.g., VPN software, network tools).
- Right-click the suspected process and select End task.
- Retry the action that triggered the error.
If the error disappears, you’ve found the conflicting program! Consider updating or reinstalling it.
Step 3: Update Network Adapter Drivers
Outdated or corrupt drivers often cause resource conflicts.
- Press Windows + X and select Device Manager.
- Expand Network adapters.
- Right-click your network device (e.g., Wi-Fi adapter) and select Update driver.
- Choose Search automatically for updated driver software.
- Follow the prompts and restart your PC if needed.
If no updates are found, visit your device manufacturer’s website for manual driver downloads.
Step 4: Run Network Troubleshooter
Windows has a built-in troubleshooter that can automatically detect and fix network problems.
- Go to Settings > Network & Internet.
- Click Status on the left panel.
- Scroll down and click Network troubleshooter.
- Follow the on-screen instructions.
This tool is handy for resolving network-related resource issues that trigger ERROR_146.
Step 5: Check for Resource Conflicts Using Device Manager
You can check if any hardware has conflicting resources:
- Open Device Manager again.
- Click View > Resources by type.
- Expand categories like Interrupt request (IRQ) or Input/Output (I/O) to see if any device shows a conflict (marked with a yellow triangle).
- Right-click the conflicting device and select Properties > Resources tab to check details.
- Try updating or uninstalling the problematic device and then restart your computer.
Step 6: Perform a Full Malware Scan
Malware can cause unpredictable errors. Running a scan ensures no malicious software is causing resource conflicts.
- Open Windows Security by searching it in the Start menu.
- Select Virus & threat protection.
- Click Scan options and choose Full scan.
- Click Scan now and wait for the process to complete.
- Quarantine or remove detected threats and reboot your PC.
Step 7: Reset TCP/IP Stack and Network Settings
Network configuration corruption can cause ERROR_146.
- Open Command Prompt as administrator (search for cmd, right-click, Run as administrator).
- Enter the following commands one by one, pressing Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
- Restart your PC to apply changes.
Step 8: Update Windows OS
Regular updates fix known bugs and improve system stability.
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates.
- Install available updates and reboot.
