🔍 Introduction
Are you experiencing a Windows Blue Screen of Death while accessing files, connecting storage devices, installing drivers, or using applications?
One possible cause is 0x000000E8 – INVALID_CANCEL_OF_FILE_OPEN.
This error is associated with incorrect file-object handling by a kernel-mode driver. It is primarily a driver-development and kernel-level troubleshooting issue.
In this article, we will understand the exact error meaning, possible causes, diagnostic methods, and practical solutions.
⚠️ Common Causes of Error 0x000000E8
1. 🧩 Faulty Device Drivers
A kernel-mode driver may incorrectly manage a file object during file-opening or cancellation operations.
2. 📂 File System Filter Driver Problems
Third-party file-system filter drivers may contribute to file I/O problems if they incorrectly handle file operations.
Examples include drivers associated with:
Antivirus software
Endpoint security
Backup applications
File encryption
Storage monitoring
3. 🛡️ Third-Party Security Software
Certain security products use kernel-level drivers to monitor file activity. A defective or incompatible driver may cause system instability.
4. 💾 Storage Driver Issues
Incompatible or faulty storage drivers may contribute to file I/O problems.
5. 🔄 Recent Driver Updates
A recently installed or updated driver may introduce compatibility problems.
6. ⚙️ Incorrect Driver Programming
A driver may pass an invalid file object or incorrectly manage object references during an I/O cancellation operation.
7. 🖥️ Hardware and Driver Compatibility
Newly installed hardware and its associated kernel-mode driver may introduce system instability.
Note: These are investigation areas, not confirmed causes of every 0x000000E8 crash. The exact driver should be identified through crash-dump analysis.
🔧 How to Fix Windows Error 0x000000E8
Follow these troubleshooting solutions carefully.
Solution 1: Restart Your Computer
Restart Windows.
Disconnect unnecessary external devices.
Remove recently connected USB storage devices, if safe.
Check whether the error appears again.
If the BSOD continues, proceed with the next solutions.
Solution 2: Identify the Faulty Driver
If the blue screen displays a driver filename, record it.
Check recently installed or updated drivers associated with:
Antivirus and endpoint protection
Backup software
Storage controllers
USB devices
File-system filtering applications
Do not assume that a particular driver is faulty without examining the crash information.
Solution 3: Update Device Drivers
Press
Windows + X.Open Device Manager.
Identify the relevant device.
Right-click the device.
Select Update driver.
Install an appropriate compatible driver.
Restart Windows.
Download drivers from the official computer or hardware manufacturer's website.
Solution 4: Roll Back Recently Updated Drivers
If the problem started after installing a driver update:
Open Device Manager.
Locate the affected device.
Right-click and select Properties.
Open the Driver tab.
Click Roll Back Driver, if available.
Restart Windows.
Solution 5: Check Recently Installed Security Software
If the error started after installing or updating antivirus, backup, encryption, or endpoint security software:
Review the installation date.
Check the software's update history.
Look for related driver updates.
Contact the software vendor for a compatible update.
If appropriate, perform a controlled uninstall using the vendor's removal procedure.
Restart and monitor the system.
Do not leave business computers without required endpoint protection.
Solution 6: Run System File Checker
Open Command Prompt as Administrator and execute:
sfc /scannowWait until the scan finishes.
This command checks and attempts to repair protected Windows system files.
Solution 7: Run DISM
Open Command Prompt as Administrator and execute:
DISM /Online /Cleanup-Image /RestoreHealthAfter completion, execute:
sfc /scannowRestart the computer.
These commands address certain Windows component and system-file problems. They do not directly repair a defective third-party kernel driver.
Solution 8: Check Windows Updates
Press
Windows + I.Open Windows Update.
Select Check for updates.
Install applicable updates.
Restart Windows.
If the error began immediately after an update, consider rolling back the affected driver or update.
Solution 9: Check Event Viewer
Press
Windows + R.Type:
eventvwr.mscPress Enter.
Expand Windows Logs.
Select System.
Review critical and error events around the BSOD time.
Check for storage, driver, or file-system-related events.
Event Viewer may provide additional context, although it may not identify the responsible driver by itself.
Solution 10: Analyze the Minidump File Using WinDbg
This is one of the most important diagnostic steps for this particular error.
Common Windows crash dump locations:
C:\Windows\MinidumpC:\Windows\MEMORY.DMPOpen the dump file using WinDbg.
Execute:
!analyze -vReview:
Bug-check code
Bug-check parameters
Faulting module
Driver information
Stack trace
File-object and I/O-related details
The official Microsoft bug-check documentation provides the parameter definitions:
| Parameter | Description |
|---|---|
| Parameter 1 | File object passed to IoCancelFileOpen |
| Parameter 2 | Device object passed to IoCancelFileOpen |
| Parameter 3 | Reserved |
| Parameter 4 | Reserved |
Solution 11: Use Driver Verifier – Advanced Troubleshooting
Driver Verifier can help identify certain defective third-party drivers.
Open Command Prompt as Administrator:
verifierUse Driver Verifier Manager to select only suspected third-party drivers.
Important precautions:
Driver Verifier may intentionally trigger a BSOD when it detects a driver violation.
Do not select all drivers indiscriminately.
Create a backup and recovery plan first.
Avoid using it on production systems without appropriate testing.
To reset Driver Verifier settings:
verifier /resetRestart the computer. If Windows cannot start, use Safe Mode or Windows Recovery Environment to disable Driver Verifier.
Solution 12: Restore Windows to a Previous State
If the error started after a recent software or driver installation:
Enter Windows Recovery Environment.
Select Troubleshoot.
Open Advanced options.
Select System Restore.
Choose a restore point created before the problem.
Follow the instructions.
System Restore can revert certain system changes. It does not replace a backup of personal data.
