Fix Event ID 7026: Driver Failed to Load

Event ID 7026 appears in the Windows System event log when a driver that is set to start automatically fails to load during boot. The fix usually involves identifying the specific driver named in the error, checking its status in Device Manager or the registry, and either updating, disabling, or reinstalling it. Below is a step-by-step guide to resolve the issue, along with background on why it happens and how to prevent it.

What Event ID 7026 Means

Event ID 7026 is logged by the Windows kernel when a boot-start driver fails to load. The event message reads: “The following boot-start or system-start driver(s) did not load: [driver name].” This is not a crash—Windows continues to start, but the missing driver can cause hardware to malfunction, slow boot times, or system instability. The driver name is almost always listed in the event details, which is your starting point.

Common drivers that trigger this error include:

Old or incompatible graphics card drivers
Storage controller drivers (e.g., for NVMe or RAID)
Third-party antivirus or security filter drivers
Virtualization or VPN network drivers
Legacy drivers left over from uninstalled hardware

The error is more frequent after a Windows update, a driver update, or a hardware change, but it can also appear on a clean system if a driver is corrupted.

Why the Driver Fails to Load

Windows loads boot-start drivers very early in the startup process, before the full system is ready. A driver fails for one of these reasons:

Corrupted driver files – The .sys file is missing, damaged, or has wrong permissions.
Incompatible version – The driver was written for an older Windows version.
Disabled or marked for deletion – A pending operation in the registry prevents loading.
Dependency failure – Another driver or service it needs did not load first.
Hardware not present – The driver is set to start but the device is no longer connected.

Windows does not automatically retry failed boot drivers. Once it logs the error, the driver stays unloaded until you intervene.

Step-by-Step Fix for Event ID 7026

Follow these steps in order. Stop after the step that resolves the issue.

Note the exact driver name from the event details. Open Event Viewer (Win+R, type eventvwr.msc), go to Windows Logs > System, find the 7026 event, and copy the driver name (e.g., MyDriver.sys).
Check Device Manager (Win+X > Device Manager). Look for a device with a yellow warning icon. If found, right-click it and select Update driver > Search automatically. If that fails, uninstall the device and restart—Windows will reinstall the driver.
Check the driver’s status in the registry. Open Regedit (Win+R, type regedit) and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<driver name>. Look at the Start value: 0 = boot start, 1 = system start, 2 = auto, 3 = manual, 4 = disabled. If it’s 4, the driver is disabled; change it to 0 or 1 if the hardware is present, or leave it disabled if the hardware is gone.
Run System File Checker to repair corrupted system files. Open Command Prompt as administrator and run sfc /scannow. Then run DISM /Online /Cleanup-Image /RestoreHealth.
Reinstall the driver from the manufacturer’s website. Uninstall the current driver in Device Manager (check “Delete the driver software for this device”), then install the latest version.
If the driver is from a third-party security suite, temporarily disable its self-protection and reinstall the software. If the issue persists, uninstall the suite and use the vendor’s cleanup tool.
If the driver is orphaned (no hardware uses it), you can disable it. In the registry, set Start to 4. This stops the error without affecting hardware that isn’t present.

How to Identify the Problem Driver

The event message itself names the driver, but sometimes the name is cryptic (e.g., tcpip.sys is normal, vwififlt.sys is a Wi-Fi filter). To find what the driver belongs to:

Search the filename online—most driver names are documented.
Open Device Manager, click View > Show hidden devices, and look for greyed-out entries that match the name.
Use the driverquery command in Command Prompt (admin) to list all drivers and their status.
Check the DisplayName value in the registry key mentioned above—it often contains a friendly name.

If the driver is a Microsoft system driver (like partmgr.sys), the issue is likely corruption, not incompatibility.

Common Mistakes and Misconceptions

Mistake: Ignoring the error because Windows seems fine. Even if the system boots, the missing driver can cause intermittent crashes or hardware that doesn’t work. It’s worth fixing.

Mistake: Disabling a driver that is actually needed. If you disable a storage or network driver, you may lose access to your disk or internet. Only disable a driver if you are certain the hardware is not in use.

Misconception: Event ID 7026 always means a virus. While malware can replace drivers, most 7026 errors are due to outdated or corrupted legitimate drivers. Run a full antivirus scan as a precaution, but don’t assume the worst.

Misconception: Updating Windows will fix it automatically. Windows Update may install a newer driver, but if the problem is a third-party driver, you often need to manually update it from the manufacturer.

Preventing Future 7026 Errors

Always install drivers from the hardware manufacturer’s website, not from generic download sites.
Create a system restore point before installing new drivers or major Windows updates.
Uninstall old drivers properly using Device Manager (with the “delete driver software” checkbox) when removing hardware.
Keep your BIOS/UEFI updated—some boot drivers depend on firmware features.
If you use a driver update tool, choose one that creates backups before replacing drivers.

When to Consider a Clean Install

If you have tried all the steps above and the error persists, or if multiple drivers fail to load, a deeper system issue may exist. A Windows repair install (using the “Reset this PC” option that keeps your files) can fix corrupted system files. A full clean install is the last resort—it wipes the drive, so back up your data first. This is rare; most 7026 errors are resolved by updating or disabling a single driver.

Frequently Asked Questions

Q: Is Event ID 7026 dangerous?
A: Not by itself. It indicates a driver didn’t load, which can cause hardware issues, but it’s not a security threat. However, it may be a symptom of a deeper problem like disk corruption.

Q: Can I ignore Event ID 7026 if my computer runs fine?
A: You can, but you risk instability. The driver might be needed later (e.g., a Wi-Fi driver that only loads when you connect to a network). It’s safer to fix it.

Q: How do I find the driver name if the event log doesn’t show it?
A: Right-click the event and select “Event Properties.” The driver name is in the “General” tab. If it’s truncated, copy the full message from the “Details” tab.

Q: What if the driver is from an old printer or scanner I no longer use?
A: You can safely disable it. In the registry, set the Start value to 4. Or uninstall the device from Device Manager with “Show hidden devices” enabled.

Q: Will this error cause data loss?
A: No, the error itself doesn’t affect your files. However, if the failed driver is for your disk controller, you might not be able to access the drive until you fix it.

Q: Does this error appear in Windows 10 and Windows 11?
A: Yes, both versions log Event ID 7026. The fix steps are identical.
