You cannot safely apply a code-specific fix to 0x800700422 yet. The reviewed Microsoft material does not establish that nine-digit string as a standard Windows error, and the extra final 2 may be a transcription or display mistake. Reopen the original dialog, Windows Update history, Event Viewer entry, or installer log and copy the complete code and message. If the value is actually 0x80070042, investigate a network-resource problem; if it is 0x80070422, investigate a disabled or stopped Windows Update service. Those are different errors with different remedies.
Why is 0x800700422 difficult to fix?
0x800700422 is not established in the available Microsoft documentation as a standard Windows error code. The token 2020 in the title is also unexplained; it may be a year or a transcription artifact rather than part of the error. Treat both as clues to verify, not as repair instructions.

Windows displays hexadecimal values in several places, and a single missing or extra digit can point to a different subsystem. Applying instructions for a similar-looking code can therefore disable the wrong service, change unrelated settings, or hide the original evidence.
How do I verify the exact error before changing Windows?
- Reopen the source. Display the original dialog, Windows Update history entry, Event Viewer event, or installer log. Copy every character after
0x, the full sentence around it, the application or Windows component, and the time of failure. - Record the environment. Press
Win+R, enterwinver, and note the Windows edition and build. Also record the update KB number or installer name. - Describe the failure stage. Note whether it occurred during download, preparation, installation, restart, Microsoft Store activity, network access, or while launching a separate installer.
- Restart once, then check again. If the message or code changes after the restart, treat the new value as a separate diagnostic input; do not combine two codes into one repair plan.
- Preserve evidence. Save the relevant Event Viewer details, installer logs, Windows Update logs,
CBS.log, and command output before clearing caches or making broad changes.
What is the difference between 0x800700422, 0x80070042 and 0x80070422?
The final digits and the subsystem producing the message determine which troubleshooting branch is appropriate. Use the table only after comparing it with the original evidence.

| Exact value | Documented meaning or association | Likely area to investigate | Do not assume |
|---|---|---|---|
0x800700422 |
Not established as a standard Microsoft code in the reviewed material | Recheck the source, message, component and logs | Do not apply a Windows Update or network fix based on the string alone |
0x80070042 |
Win32 error 66 (0x42), ERROR_BAD_DEV_TYPE: “The network resource type is not correct.” |
Network shares, mapped drives, installer sources and other network resources | Do not silently convert it into a Windows Update diagnosis |
0x80070422 |
Separate value associated by troubleshooting guidance with a disabled or stopped Windows Update service | Windows Update service state and the update operation that failed | Do not apply this branch to 0x80070042 or the nine-digit string |
What does 0x80070042 mean?
Microsoft Learn defines Win32 error 66, hexadecimal 0x42, as ERROR_BAD_DEV_TYPE, “The network resource type is not correct.” The definition identifies the status condition, not the application that produced it. If your confirmed message is 0x80070042, identify the network path or resource involved instead of assuming Windows Update is responsible.
Is 0x800700422 the same as 0x80070422?
No. 0x80070422 is an eight-digit value associated with a disabled or stopped Windows Update service in the relevant troubleshooting guidance. 0x800700422 has an additional trailing digit and is not validated as the same condition.

How do I troubleshoot a confirmed 0x80070042 network-resource error?
Follow this branch only when the original evidence contains exactly 0x80070042 and the failure involves a network resource.
- Identify the resource. Write down the UNC path, mapped-drive letter, share name, installer location, or other network address shown in the message or log.
- Test the path independently. Open the same share or installer location in File Explorer using the account that encountered the error. A path that is unavailable, redirected, or resolving to the wrong host can produce a resource-type failure.
- Check the mapped drive. If the operation uses a drive letter, confirm that it is connected in the same user session. A drive mapped for one account may not exist for an elevated installer or service.
- Review permissions. Confirm that the account has access to the share and to the required files. Ask the administrator of the share to verify access rather than changing permissions blindly.
- Check the installer source. If setup is running from a network location, copy the installer to a local folder approved by your organization and retry only if policy permits. Keep the original log so you can compare the result.
- Escalate with context. Provide the exact path, account context, Windows build, application name and timestamp. Microsoft’s error definition alone cannot identify which program supplied the invalid resource type.
How do I troubleshoot a confirmed 0x80070422 Windows Update error?
Use this branch only when the original dialog or log confirms the eight-digit value 0x80070422 and the operation is Windows Update-related.

- Open the service manager. Press
Win+R, enterservices.msc, and locate Windows Update. Record its status and startup setting before changing anything. - Check for an intentionally managed service. A work or school computer may have policies that control update services. If the service is managed by your organization, contact its administrator instead of overriding the policy.
- Start the service only when appropriate. If it is stopped and you have permission to manage the device, use the service manager’s start command, then retry the same update and record the new result. If it stops again, preserve the service error and Event Viewer details.
- Match the repair to the failure stage. Download, preparation, installation and restart failures can have different causes. Record the KB number and stage rather than treating every update failure as a service problem.
- Follow Microsoft’s guidance for this exact value. Do not substitute instructions written for
0x80070042or for the unverified0x800700422string.
When should I run DISM and SFC?
Use system-file repair when the logs or symptoms point to missing or corrupted Windows components, not merely because a code looks unfamiliar. Microsoft Support warns that when critical Windows system files are missing or corrupted, the operating system may malfunction.
- Open Command Prompt as an administrator.
- Run
DISM.exe /Online /Cleanup-image /Restorehealthand wait for it to finish. Do not close the window while the operation is running. - After DISM completes, run
sfc /scannow. - Record the exact completion message and any repair details, then restart and retry the original operation once.
- Keep the resulting command output with
CBS.logand the original application or update logs.
DISM precedes SFC in Microsoft’s documented workflow because SFC may need a healthy component source to replace damaged files. If either command reports an error, preserve that text for escalation rather than repeatedly rerunning it without new evidence.

Frequently Asked Questions
Could 0x800700422 indicate malware?
The code alone is not evidence of malware or an infection. Treat it as an identification problem first, and use your normal security software and organizational policy for separate security checks.

Should I reset Windows Update components immediately?
Not before you copy the original message and logs. A broad reset can remove useful history and still leave you troubleshooting the wrong code, especially when the displayed value may contain an extra digit.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Can Safe Mode prove which component caused the error?
Safe Mode loads a reduced set of drivers and services, so a different result can help isolate interference but does not identify the original code’s meaning. Use it as a controlled diagnostic comparison after recording the normal failure, not as a substitute for verifying the hexadecimal value.
Why might the error appear only once?
Transient network availability, a service state change, or a one-time installer condition can make the message disappear after a restart. Keep the first screenshot or log entry anyway, because a later successful attempt does not explain what produced the original failure.
