That means Windows cannot be assigned one reliable cause or one universal fix from the hexadecimal value alone. The correct repair depends on where it appears: during Windows Update or an upgrade, inside a particular application, after a driver or device change, or alongside a crash, blue screen, black screen, or unexpected restart.
Start by recording the complete message and the event that triggered it. Then follow the troubleshooting branch that matches that context. The steps below begin with reversible diagnostics, avoid speculative registry edits, and show what evidence to collect if Microsoft or the affected software vendor must investigate.

What error 0x0090C60D means
A dedicated search for 0x0090C60D and 0090C60D found no indexed Microsoft article or vendor bulletin that defines the code. It is therefore not possible to say, from the number alone, whether it represents an update failure, an application fault, a driver problem, or a hardware issue. The same-looking value can be displayed by different components, and changing a registry value or downloading a generic “error fixer” without knowing the emitting component can make diagnosis harder.
Treat the code as a clue, not a diagnosis. The words around it, the window that displayed it, the time it appeared, and any related log entry are more useful than the hexadecimal string. A complete message such as an update failure, a setup rollback, an application crash, or a restart warning points to a different owner and therefore a different support channel.

Capture the context before changing Windows
Write down the details while the message is still visible. If you have already dismissed it, reproduce the event only once if doing so is safe; repeated retries can overwrite useful log entries.
- Copy the full dialog. Record every line, including a button label, a filename, a KB number, a setup phase, or a second error code. A screenshot is useful, but transcribe the text as well so it can be searched and quoted.
- Identify the emitting screen. Note whether the code appeared in Settings > Windows Update, Windows Setup, a named application, Device Manager, a game launcher, firmware utility, or a blue/black-screen or restart message.
- Record timing and changes. Write down the first occurrence, whether it happens at startup or only after a particular action, and any Windows update, application installation, driver installation, peripheral connection, or hardware replacement immediately beforehand.
- Record your Windows build. Press Windows+R, enter
winver, and note the edition and version shown. In Settings, you can also open System > About and copy Windows specifications. - Check the relevant log. Search for “Event Viewer,” open it, and inspect Windows Logs > Application for an application failure or Windows Logs > System for a device, driver, restart, or update event at the same time. For an upgrade, also preserve any setup-log path or line shown by Windows Setup.
Keep this record unchanged until you know which path applies. It gives support staff the component name and timing they need; the code by itself does not.
Choose the troubleshooting path
| Where the code appears | First actions and relative risk | Evidence to retain | Escalation target |
|---|---|---|---|
| Windows Update or an upgrade screen | Remove nonessential peripherals, restart, run the Windows Update Troubleshooter, and retry. These are reversible checks. | Windows edition/version, update or KB number, complete dialog, setup-log line | Microsoft Support |
| A named application | Close and reopen the application, check its own repair or update option, and review its Application event. Avoid registry changes until the vendor identifies a cause. | Application name and version, action that triggers the error, full message, Event Viewer entry | The application vendor |
| After a device or driver change | Disconnect the newly added device when safe, boot with minimal hardware, and investigate the related driver or recently installed software. | Device model, driver change date and version, System event, device symptoms | Hardware or driver vendor; Microsoft when Windows itself is implicated |
| Crash, blue/black screen, or repeated restart | Remove newly added hardware, use Safe Mode, and isolate drivers or software. These steps preserve the system better than random repairs. | Stop or restart text, dump or Event Viewer details, recent hardware/software changes | Microsoft Support or the named hardware/software vendor |
When 0x0090C60D appears during Windows Update or an upgrade
Microsoft’s upgrade guidance advises trying general fixes before searching for a specific error code. Follow this order so each retry tests one clear change.
1. Disconnect nonessential peripherals
Shut down Windows and unplug printers, scanners, USB storage, external disks, docks, and other devices that are not required for the update. Leave the display, keyboard, mouse, network connection, and any hardware Windows needs to start. A peripheral can hold a driver or storage volume open during setup; removing it is a reversible diagnostic, not a permanent repair.
2. Restart, then run the Windows Update Troubleshooter
Restart normally before launching another update attempt. On Windows 11, open Settings > System > Troubleshoot > Other troubleshooters, select Windows Update, and choose Run. On Windows 10, open Settings > Update & Security > Troubleshoot > Additional troubleshooters, select Windows Update, and choose Run the troubleshooter. Apply only the changes it reports, restart if requested, and try the same update again.

The troubleshooter is designed to help resolve problems encountered while downloading and installing updates; it does not establish what 0x0090C60D means. If the code returns, preserve the troubleshooter result and the exact update name rather than repeating the same cycle.
3. Identify the update and Windows build
Open Settings > Windows Update > Update history and note the failed update’s KB number or description. Compare it with the edition and version from winver. An update package is tied to a particular Windows release and architecture, so do not download a similarly named package until those details match.
4. Check the common causes of a persistent update failure
- Corrupted update files: note whether the failure occurs during download, installation, or restart. A failure at one stage gives Microsoft support a more useful lead than the code alone.
- Permissions: confirm that the update is being run from the normal administrator-controlled Windows session and that no organization policy is blocking servicing.
- Third-party security software: temporarily investigate whether installed security software is interfering, following that product’s documented pause or uninstall procedure. Do not leave protection disabled longer than necessary.
- Servicing prerequisites: Microsoft Learn recommends installing the latest matching Servicing Stack Update when the servicing component is missing or outdated. Match the package to the exact Windows version and architecture.
- Superseded packages: an update may have been replaced by a newer cumulative package. Check whether the attempted update is superseded before forcing an older package.
These checks require the failed update’s identity. A generic registry cleaner, an unrelated driver package, or a random command copied from a forum cannot substitute for identifying the package and the servicing state.
5. Use the Microsoft Update Catalog only for an identified package
If Microsoft Support or the update history identifies a specific KB and your Windows edition, version, and architecture match, the Microsoft Update Catalog can be used to locate that package. Read the package description and prerequisites, check whether it has been superseded, and create a recovery option appropriate for your environment before installing manually. Do not search the catalog for 0x0090C60D itself: the code has no documented package mapping.
6. Retry once and preserve the result
Reconnect peripherals only after the update succeeds or the failure has been documented. Retry the same update once after each material change. Record the new stage, percentage, KB number, and any changed message. If the code persists after the checks above, stop cycling through downloads and escalate with the complete evidence.

When the code accompanies a crash or unexpected restart
Microsoft notes that an unexpected restart might be caused by a hardware device, its driver, or software. The goal here is isolation, not a blind “repair.”
Remove recently added hardware
Power off and disconnect a newly installed USB device, expansion card, dock, storage device, or other nonessential hardware. If the system becomes stable, reconnect one item at a time and observe which change reproduces the failure. Do not open a powered system or remove internal components unless you are qualified to do so and the device maker’s instructions permit it.
Start Windows in Safe Mode
From the sign-in screen, hold Shift while selecting Power > Restart. Choose Troubleshoot > Advanced options > Startup Settings > Restart, then select Safe Mode. Safe Mode loads a minimal set of drivers and services. If the crash and 0x0090C60D do not occur there, a normal-start driver or recently installed program becomes a stronger lead; it is not proof of a specific culprit.
In Safe Mode, note Device Manager warnings and uninstall or roll back only the recently changed component when you can identify it. Restart normally after each controlled change. If Windows cannot reach the sign-in screen, use the same Advanced options route from Windows Recovery Environment after two interrupted starts, or use recovery media supplied for your installation.
Review software changes
Uninstall a recently added application or driver only when its name and timing match the symptom. Prefer the vendor’s documented uninstaller and keep installation media or a reinstall path available. If removing the change stops the crash, preserve its version and the event log entry for the vendor instead of assuming every system with this code has the same defect.

When a named application shows the code
An application dialog is the strongest indication that the application, one of its files, or a component it calls is the emitting source. Capture the application name, version, exact action that triggers the message, and the Application log entry at that timestamp.
Use the application’s own maintenance options
Look in the application’s Help, Settings, Apps & features entry, or installer for an update, repair, reset, or diagnostic option. Use a repair option before uninstalling when the application offers one. If the vendor documents a clean reinstall, export or back up the application’s data first and follow its sequence exactly.
Separate an application fault from a Windows fault
Test whether other applications perform the same action successfully. A failure limited to one program points toward that vendor; a system-wide failure after a driver or update change points toward Windows, a device, or shared software. Do not infer a registry key or replace a system DLL from the hexadecimal code alone.
When a driver or device is involved
If the message appears while connecting a printer, adapter, graphics card, audio device, Bluetooth accessory, Wi‑Fi adapter, or USB device, record the model and the driver version shown before changing it. In Device Manager, expand the relevant category, open the device’s Properties, and inspect the Driver tab and the Events tab. A recent change gives you a reason to test a rollback; a missing or corrupted driver gives you a reason to obtain the exact package from the device maker or Windows Update.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Disconnect the device and restart to see whether the symptom disappears. Reconnect it directly rather than through a hub when that is safe, and test one device at a time. Avoid installing a driver merely because its date is newer: match the model, Windows edition, architecture, and the vendor’s release notes. If the device is essential and the failure continues, provide the model, driver version, and System log entry to the hardware vendor.
Read logs without guessing
Event Viewer can provide the component name that the hexadecimal value lacks. Open Event Viewer, choose Windows Logs, and inspect Application and System around the exact minute of the failure. Use Filter Current Log to narrow the time range and look for the source, event ID, failing application, module, device instance, or update service named in the entry.
For an upgrade, preserve the setup-log filename and the line surrounding the failure. For a crash or restart, preserve the stop or restart text and any dump reference Windows provides. Do not edit or delete logs before exporting or copying the relevant entry. A support request that includes the full message, source, event ID, timestamp, Windows edition/version, and recent changes is substantially more actionable than “0x0090C60D won’t go away.”
What not to download
No trustworthy physical product, recovery accessory, or generic utility is tied to this exact undocumented code. Be cautious of pages promising a guaranteed download, a one-click registry repair, or a “100%” fix based only on the hexadecimal string. Such claims do not identify the component that generated the message.

For update failures, use Windows’ troubleshooter and an identified package from Microsoft’s catalog. For application failures, use the named vendor’s repair guidance. For device failures, use the exact hardware maker’s driver and support channel.
When to escalate
Contact Microsoft Support when the code occurs in Windows Update, Windows Setup, recovery, or a system crash and remains after the context-specific steps. Contact the application vendor when only its program displays the dialog. Contact the hardware or driver vendor when a specific device reproduces the problem and its model and driver details are available.
Include the complete dialog, Windows edition and version, application or device name, exact trigger, first occurrence, recent changes, Event Viewer source and event ID, and any setup-log line. State which reversible steps you tried and what changed after each one. This prevents support from repeating generic advice and helps them determine which component owns the code.
Bottom line
Error 0x0090C60D is not defined by the Microsoft or vendor documentation reviewed, so there is no evidence-based universal command, registry edit, download, or replacement part for it. Capture the surrounding message, follow the branch for Update, application, device, or crash symptoms, and escalate with logs when the controlled checks do not identify the cause.
