How to Fix the ERROR_OPERATION_IN_PROGRESS BSoD Error

The ERROR_OPERATION_IN_PROGRESS with an error code 329 (0x149) and description An operation is currently in progress with the device or mount error(115) with description operation now in progress appears can appear if Windows is already performing an operation at the same time.

This error can appear when you try to access a device that is currently in use, and it can happen with mounting disks or network drives. First, wait for the process to be completed, then go to Task Manager to check the disk usage and close the unwanted processes. Next, safely remove the external storage device or USB drive connected to your device and restart your PC.

How can I fix the ERROR_OPERATION_IN_PROGRESS error?

1. Run a malware scan

1. Press the Windows key, type windows security in the search box, and click Open from the list of options.  
2. On the Windows Security window, go to Virus & threat protection.
3. Click Scan options.
4. Select Full scan and click Scan now.

Wait for the scan to complete, and remove the malicious items detected by the tool. If you have a third-party antivirus app, you can run a full scan using that instead.

2. Run the CHKDSK command

1. Press the Windows key, type cmd in the search box, and click Run as administrator to launch Command Prompt with administrator privileges.
2. Type the following command to run the diagnostic and repair tool in Windows that checks the integrity of the file system and hard drive, and press Enter: Chkdsk C: /f /r
3. If the disk is already in use, you will be prompted to schedule the scan after restarting. Type Y and hit Enter.

After you restart your computer, the scan will initiate and fix repairing file system errors and bad sectors. Once done, your computer will start, and you will get the login screen.

3. Check for Windows Updates

1. Press Windows + I to open the Settings app.
2. Go to Windows Update, and click the Check for updates button.
3. If there is an update available, click Download & install.

4. Reboot your PC into safe mode

1. Press Windows + R to open the Run window.  
2. Type msconfig and click OK to open the System Configuration window.
3. Go to the Boot tab, under Boot options, select Safe boot and Network.
4. Click Apply, then OK to save the changes.
5. Click Restart.

Your computer will restart with a minimal set of drivers and network connection so that you can figure out which third-party app, or service is causing the ERROR_OPERATION_IN_PROGRESS error.

5. Stop the indexing services temporarily

1. Press Windows + R to open the Run window.
2. Type services.msc and click OK to open the Services window.
3. From the list of services, locate & click Windows Search, and select Stop the service from the left side.
4. Now, look for any service related to monitoring and stop it.

If you see the ERROR_OPERATION_IN_PROGRESS again, you can start these services.

6. Update/Reinstall device drivers

1. Press Windows + R to open the Run window.  
2. Type devmgmt.msc and click OK to open the Device Manager app.
3. You will get the list of system components, expand the categories one by one, and look for a driver with a yellow triangle icon and an exclamation mark inside.
4. Once you have located the driver, right-click it and choose Update driver from the context menu.
5. Select the Search automatically for drivers option.

Windows will try to find the best driver version, but if Windows fails, you can go to the manufacturer’s website and download the latest version. Alternatively, you can download and install a third-party driver updater tool to ensure all the drivers stay up to date. In case you find multiple problematic drivers, repeat the same steps.

If updating the drivers doesn’t fix the ERROR_OPERATION_IN_PROGRESS issue, try reinstalling the driver using these steps:

1. Relaunch the Device Manager app, right-click the driver with the yellow triangle, and select Uninstall device from the context menu. 
2. Go to Action and select Scan for hardware changes from the drop-down menu to reinstall the driver.

In conclusion, to fix the ERROR_OPERATION_IN_PROGRESS issue, you can run a malware scan, reboot your PC in safe mode, check for Windows updates, stop Windows indexing services, or update/reinstall device drivers.
