Error 0x009EEE5A is not defined in the Microsoft material available for Windows 10 or Windows 11, so the code alone cannot identify a cause or prove that your PC is infected. Treat it as a clue: first capture the complete message, the application or Windows component that displayed it, and what changed immediately before it appeared. Then run Microsoft’s Error Lookup Tool and follow the troubleshooting route that matches the context—activation, Device Manager, an application crash, or a startup/stop error.
An unrecognized lookup result is useful evidence, not a malware diagnosis. The safest fix is therefore to identify where the code appears, apply the corresponding Windows procedure, and send Microsoft or the affected application’s vendor the full details if the code remains unresolved.

What does error 0x009EEE5A mean on Windows?
Windows status values are hexadecimal codes, but a code is meaningful only when it is tied to the component that generated it. The exact value 0x009EEE5A is not defined in the authoritative Microsoft guidance used for this article. That means there is no evidence-based way to name a particular driver, file, update, or malware family from the number alone.
Do not replace the code with a guess. A dialog from an activation service, a Device Manager entry, a game or business application, and a blue-screen report can all present hexadecimal values while requiring completely different fixes. The surrounding wording and the component name are more useful than the number by itself.

What should I record before trying a fix?
Write down the details while the message is still visible. If the computer is restarting, use a phone to photograph the screen or copy the text from the next report.
- The complete error text, including any decimal number, HRESULT, file name, or “stop code” shown beside
0x009EEE5A. - The window title and the application or Windows component that displayed it.
- Whether it appeared during sign-in, activation, printing, gaming, installing software, connecting a device, or starting Windows.
- The exact time it started and whether Windows still boots normally.
- Changes made immediately beforehand, such as a Windows update, driver installation, new device, service, app, or security setting.
- Any Device Manager warning icon, named hardware, event ID, dump-file name, or repeated pattern.
This record prevents you from applying a driver procedure to an activation problem or changing recovery settings when only one application is failing.
How do I look up 0x009EEE5A with Microsoft’s tool?
Microsoft says, “The Microsoft Error Lookup Tool displays the message text that is associated with a hexadecimal status code.” The utility reads Windows header files and is point-in-time software, so a newer status code may require a newer download.
- Download the current Microsoft Error Lookup Tool from Microsoft’s official support or download channel.
- Open Command Prompt in the folder containing the executable.
- Run
Err_6.4.5.exe <error code>, replacing the placeholder with0x009EEE5A. - Compare the returned text with the complete message you recorded. Keep the output with your notes.
If the tool says the value is not recognized, that does not show that Windows is infected or that the code is fake. It means this version of the lookup database has no associated message. Continue with the context-based checks below and include the unrecognized result when you contact support.
Which troubleshooting route fits the screen where the code appeared?
Use the location of the message as the primary decision point. A recent change, boot status, and named device then refine the choice.

| Where the code appears | What to check first | Initial Windows route |
|---|---|---|
| Activation dialog or activation settings | Windows edition and activation status | Confirm with winver, then run the Activation troubleshooter in Get Help |
| Device Manager entry | Warning icon and named device | Uninstall the device, restart, and scan for hardware changes; use the hardware maker’s driver if Windows cannot provide one |
| One application’s dialog or crash | Application name, recent app or driver change, and event records | Check the application’s support path and Event Viewer while isolating recently added drivers or services |
| Blue screen, stop screen, or repeated restart | Recent driver/service, warning icons, and System log events | Use Safe Mode to isolate startup drivers, then updates or recovery options |
| WHEA-style hardware report | Device named in the report and recent hardware or driver change | Update through Windows Update or the device maker; consider System Restore or Startup Repair after a recent change |
How do I fix the code in an activation message?
Activation errors need the licensing and edition checks, not a driver replacement. Microsoft provides separate activation guidance for Windows 11 and Windows 10.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- Press
Windows, typewinver, and open it. Record the Windows version and edition shown in the About Windows dialog. - Open the Get Help app from Start.
- Search for the automated Activation troubleshooter and run it. Follow the checks it presents for your edition and activation state.
- Review any code-specific guidance displayed by the troubleshooter. Do not infer a licensing cause from
0x009EEE5Aif the tool does not associate that value with activation. - If the troubleshooter does not list the code or cannot resolve the activation state, contact Microsoft Support and provide the full dialog text, edition from
winver, and the troubleshooting result.
A code shown in an activation window should not be “fixed” by deleting registry entries or installing a generic repair utility. Those actions do not establish a valid license or identify the activation service that generated the message.
How do I fix it when Device Manager names a device?
When the value appears beside a device, follow Microsoft’s Device Manager workflow and identify the hardware before changing anything.
- Right-click Start and open Device Manager.
- Expand the category containing the warning icon. Open the device’s Properties and record its name, manufacturer, and the message under Device status.
- If the device is reported as having a corrupted driver, right-click it and choose Uninstall device. Confirm the removal.
- Restart Windows. After sign-in, open Device Manager again.
- Select Action > Scan for hardware changes. Windows will rediscover the hardware and attempt to install an available driver.
- If Windows cannot supply a driver, obtain the package from the hardware vendor for your exact model and Windows edition. Avoid a package for a different revision or operating system.
If the code is not listed in the device’s status information, Microsoft advises referring to the hardware vendor or Microsoft Support. Keep the device name, hardware identifiers, driver version, and the exact message in your support request.
What should I do if an application shows the error or crashes?
An application dialog does not prove that Windows itself generated the status value. Start by isolating the application and the change that preceded the failure.

- [Dont Hesite to Order] 24 hours customer services and professional technology team are standing by
- Note the application’s exact name and version, the action that triggers the message, and whether other applications work normally.
- Undo or update the application’s most recent change using its own support instructions. If a device or driver was added at the same time, use the Device Manager route rather than replacing unrelated system files.
- Open Event Viewer by searching for it from Start. In Windows Logs, inspect Application and System entries at the time of the crash. Record the event source, event ID, faulting module, and timestamp.
- Test whether the failure occurs with a different user profile or after a clean restart, if the application supports that test. A failure limited to one application should be reported to that application’s vendor with the captured log details.
- Do not delete DLLs, edit registry values, or install a “one-click” cleaner solely because the hexadecimal value looks unfamiliar. Those actions can remove evidence and create additional failures.
How do I handle a blue screen, stop error, or repeated restart?
For a crash that affects Windows startup, Microsoft recommends checking recently added drivers or services, Device Manager warning icons, and the System log. Safe Mode can help separate a startup driver from the core operating system.
- Disconnect recently added nonessential hardware and note any driver or service installed immediately before the first crash.
- If Windows starts, open Device Manager and look for warning icons. Record the affected device instead of uninstalling unrelated hardware.
- Open Event Viewer > Windows Logs > System and review events around the crash time. Save the source, event ID, and message.
- If Windows cannot start normally, enter the Windows Recovery Environment and choose Startup Settings > Restart, then select Safe Mode. If the crash stops in Safe Mode, investigate a recently added driver or service first.
- Remove or roll back the specifically identified driver or service using the vendor’s instructions. Restart normally and test the original action.
- If the problem began after a recent update, driver, or application, use System Restore when a restore point exists. Use Startup Repair when Windows cannot complete startup.
Keep recovery changes reversible. If Safe Mode shows the same failure, the cause may not be a startup driver; use the event details and the complete stop-screen text when escalating.
What if the message appeared after a Windows update or hardware change?
A timing coincidence does not prove that an update caused 0x009EEE5A, but it makes rollback and recovery checks reasonable.
- Run Windows Update and install offered driver updates for the affected hardware.
- If Windows identifies a particular device, check the device maker’s current driver and installation instructions instead of applying a package intended for another model.
- For a failure that began immediately after an update, driver, or app, use System Restore if an appropriate restore point is available.
- If the update left Windows unable to boot, start Windows Recovery Environment and run Startup Repair.
- Retest the original operation and record whether the code changes, disappears, or moves to a different component.
Do not conclude that every appearance after an update is an update bug. The captured event, device, or application information is needed to connect the timing to a component.

Is 0x009EEE5A a virus?
There is no evidence that this code is a virus identifier. A hexadecimal status value can be produced by an ordinary Windows component or an application, and an unrecognized lookup result is not proof of malware.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When should I contact Microsoft or the application’s vendor?
Escalate when the code remains unrecognized, the relevant workflow fails, or Windows cannot boot reliably. Send a compact evidence package rather than only the hexadecimal value.
- Complete on-screen text and a photo or screenshot.
- Windows edition and version from
winver. - Application name and version, or the exact device model and hardware identifiers.
- What changed immediately beforehand and whether the issue is reproducible.
- Error Lookup Tool output, Event Viewer source and event ID, and any stop-screen or WHEA details.
- Steps already attempted and their results.
Microsoft Support is the appropriate destination for an activation problem, an unlisted Windows status, or a startup failure. The hardware vendor is the better first contact when Device Manager identifies its device. For a single application’s dialog, contact that application’s vendor with the same evidence.

FAQ
Can I identify the owner of 0x009EEE5A from the digits alone?
No. The value has no established Microsoft definition in the available authoritative material, and hexadecimal formatting does not reveal which application or device created it. The window title, component name, and adjacent text are required to identify the owner.
What if Error Lookup Tool works on another computer but not mine?
The utility relies on its bundled, point-in-time Windows header information. A newer or different tool download can contain a message your copy lacks, so record the tool version and the exact output when comparing systems.
Should I reset Windows immediately?
Usually not. Resetting can remove applications and settings before you have captured the event, device, or activation details needed for diagnosis; use the matching troubleshooting branch and recovery options first.
Do these 3 things before closing this tab:
